I am looking to load repeated elements from an XML file I have called initialInspections.xml. The problem is that the system needs to be dynamic and to allow as many different inspectionNotes to be added. I need to input all of them even though they have the same name.
If someone could please give me a method of doing this I would be extremely appreciative, since I have been searching for almost 3 hours now and I haven't found anything that works.
I need all off the data from within each inspectionNote node, and it will be put into an array of a structure called initialInspectionNotes.
Here is what I have up to now:
public int propertyID;
public string initialInspectorUsername;
public DateTime intialDateTime;
public struct initialInspectionNotes
{
public string locationWithinProperty;
public string locationExtraNote;
public string costCode;
public float estimatedTime;
}
private void finalInspection_Load(object sender, EventArgs e)
{
//Open the intialInspections xml file and load the values into the form
XmlDocument xdoc = new XmlDocument();
FileStream rFile = new FileStream(values.xmlInitialFileLocation, FileMode.Open);
xdoc.Load(rFile);
XmlNodeList list = xdoc.GetElementsByTagName("initialInspection");
for (int i = 0; i < list.Count; i++)
{
XmlElement initialInspection = (XmlElement)xdoc.GetElementsByTagName("initialInspection")[i];
XmlElement initialInspector = (XmlElement)xdoc.GetElementsByTagName("userInspection")[i];
XmlElement dateTime = (XmlElement)xdoc.GetElementsByTagName("dateTime")[i];
propertyID = int.Parse(initialInspection.GetAttribute("propertyID"));
initialInspectorUsername = initialInspector.InnerText;
intialDateTime = DateTime.Parse(dateTime.InnerText);
}
rFile.Close();
}
The XML looks like this:
<?xml version="1.0" standalone="yes"?>
<initialInspections>
<initialInspection propertyID="1">
<userInspection>defaultadmin</userInspection>
<dateTime>07/11/2015 17:15:20</dateTime>
<inspectionNote>
<location>Dining Room</location>
<locationNote>Remove whole carpet, leave underlay</locationNote>
<CostCode>L1</CostCode>
<estimatedTime>5</estimatedTime>
</inspectionNote>
<inspectionNote>
<location>Other - See Notes</location>
<locationNote>On the marked area with orange spray paint.</locationNote>
<CostCode>B1</CostCode>
<estimatedTime>12</estimatedTime>
</inspectionNote>
</initialInspection>
</initialInspections>
Any help would be much appreciated.
class Note
{
public string Location { get; set; }
public string LocationNote { get; set; }
public string CodeCost { get; set; }
public string EstimatedTime { get; set; }
}
var xml = XElement.Load(...your xml path here );
var data = xml.Descendants("initialInspection").Elements("inspectionNote").Select(n => new Note()
{
Location = n.Element("location").Value,
LocationNote = n.Element("locationNote").Value,
CodeCost = n.Element("CostCode").Value,
EstimatedTime = n.Element("estimatedTime").Value
}).ToList();
One possibility would be to use the LINQ2XML and the LINQ Descendants method to fetch all inspectionNotes at once:
var xml = XDocument.Load(fileLocation); // for example c:\temp\input.xml
// fetch all inspectionNotes
var inspectionNotes = xml.Root.Descendants("inspectionNote").ToList();
// TODO: error handling!
// map inspectionNote node to custom structure
var arrayOfNotes = inspectionNotes.Select (n => new initialInspectionNotes
{
costCode = n.Element("CostCode").Value,
estimatedTime = float.Parse(n.Element("estimatedTime").Value),
locationExtraNote = n.Element("locationNote").Value,
locationWithinProperty = n.Element("location").Value,
})
// and convert the result to array holding elements of the custom structure
.ToArray();
foreach (var note in arrayOfNotes)
{
Console.WriteLine(note.locationExtraNote);
}
The output is:
Remove whole carpet, leave underlay
On the marked area with orange spray paint.
Same logic applies if you want to read and map another XML nodes (f.e. initialInspection).
If you need to use XmlReader then use XPath in order to fetch the inner inspectionNote elements and the values of every inspectionNote element, using XmlNode.SelectSingleNode and XmlNode.SelectNodes:
//Open the intialInspections xml file and load the values into the form
XmlDocument xdoc = new XmlDocument();
FileStream rFile = new FileStream(values.xmlInitialFileLocation, FileMode.Open);
xdoc.Load(rFile);
XmlNodeList list = xdoc.GetElementsByTagName("initialInspection");
// create list of initialInspectionNotes in order to add as many nodes as needed
var notes = new List<initialInspectionNotes>();
// map data
for (int i = 0; i < list.Count; i++)
{
// read data
XmlElement initialInspection = (XmlElement)xdoc.GetElementsByTagName("initialInspection")[i];
XmlElement initialInspector = (XmlElement)xdoc.GetElementsByTagName("userInspection")[i];
XmlElement dateTime = (XmlElement)xdoc.GetElementsByTagName("dateTime")[i];
propertyID = int.Parse(initialInspection.GetAttribute("propertyID"));
initialInspectorUsername = initialInspector.InnerText;
intialDateTime = DateTime.Parse(dateTime.InnerText);
// fetch notes!
var inspectionNotes = initialInspection.SelectNodes("inspectionNote");
foreach (XmlNode inspectionNote in inspectionNotes)
{
// insert data into list
notes.Add(new initialInspectionNotes
{
locationExtraNote = inspectionNote.SelectSingleNode("locationNote").InnerText,
costCode = inspectionNote.SelectSingleNode("CostCode").InnerText,
locationWithinProperty = inspectionNote.SelectSingleNode("location").InnerText
});
}
}
// convert to array if needed
//var arrayOfNotes = notes.ToArray();
rFile.Close();
Regardless of how many inspectionNote elements the XML contains, the list resp. array will read them all.
class InitialInspectionNotes
{
public string Location { get; set; }
public string LocationNote { get; set; }
public string CodeCost { get; set; }
public string EstimatedTime { get; set; }
}
var xdoc = XDocument.Load("yourpath\filename.xml");
var dataXml = xdoc.Descendants("initialInspection").Elements("inspectionNote").Select(n => new InitialInspectionNotes()
{
Location = n.Element("location").Value,
LocationNote = n.Element("locationNote").Value,
CodeCost = n.Element("CostCode").Value,
EstimatedTime = n.Element("estimatedTime").Value
}).ToList();
var xmlList = new List<object>();
for (int i = 0; i < dataXml.Count; i++)
{
xmlList.Add(dataXml[i]);
}
Despite all the answers above might have worked, I have however found it quite complicated for reading just elements. I found a simpler solution which I would like to share for future audience in this case.
Supposing you have read the document stream into XmlDocument object named as document.
var dataNodes = document.GetElementsByTagName("Data");
var toList = dataNodes.OfType<XmlElement>().ToList();
In my case, Data node was not being called repeatedly. Hence this works, now I was able to append multiple nodes with the same name.

I am trying to use csv helper libary to parse my csv. But I am having an issue it says that the itemcode does not exist when its there in the file.
// Adding stock item code
Sage.Accounting.Stock.StockItem stockItem = new Sage.Accounting.Stock.StockItem();
string line = null;
public void ImportCsv(string filename)
{
TextReader reader = File.OpenText(filename);
var csv = new CsvReader(reader);
csv.Configuration.HasHeaderRecord = true;
csv.Read();
// Dynamic
// Using anonymous type for the class definition
var anonymousTypeDefinition = new
{
Itemcode = string.Empty,
Barcode = string.Empty
};
var records = csv.GetRecords(anonymousTypeDefinition);
}
This is the csv structure
"Itemcode","Barcode","description"
"P4S100001","303300054486","Test Product"
This is my first time using the csvhelper as showing here at https://joshclose.github.io/CsvHelper/
You are better off creating a strongly typed model to hold the data if one does not already exist
public class Item {
public string Itemcode { get; set; }
public string Barcode { get; set; }
public string description { get; set; }
}
and using GetRecords<T>() to read the records by type
TextReader reader = File.OpenText(filename);
var csv = new CsvReader(reader);
var records = csv.GetRecords<Item>();
Your GetRecords function needs a type specifier like so:
var records = csv.GetRecords<type>();
Also you may want to put csv.Read() in a while loop depending on your need.
Since all your values have quotes you need to specify it in the config. Working with quotes in csvHelper is frustrating. if not all if the values have quotes there are ways to handle that as well but not as nicely as this
var csv = new CsvReader(reader,new CsvHelper.Configuration.Configuration
{
HasHeaderRecord = true,
QuoteAllFields = true
});
var anonymousTypeDefinition = new
{
Itemcode = string.Empty,
Barcode = string.Empty
};
var records = csv.GetRecords(anonymousTypeDefinition);
The XML bills usually have one Node that is returned and parsed. We have come across an issue where an XML bill had multiple Nodes. Since the code is not set up to handle that, the customer ended up with an incorrect bill.
This is the code I have that goes through the bill list. If it comes back with a node then it parses the information from the xml.
var response = new List<CustomerBill>();
try
{
foreach (GetBillForCAResponse eBillResponse in eBillResponseList)
{
var statementDetailsResponse = GetStatementDetails(
new GetStatementDetailsRequest
{
BatchId = eBillResponse.BatchId,
CustomerAccountId = eBillResponse.CA.ToString("000000000"),
StatementId = eBillResponse.CAS_NUM.ToString("0000")
});
string xmlBill = statementDetailsResponse.StatementAsXML.ToString();
var document = new XmlDocument();
document.LoadXml(xmlBill);
var saDetailedPageNode = XmlBillParser.GetDetailPageSectionBySa(requestSa, xmlBill);
if (saDetailedPageNode == null) continue;
var customerBill = new CustomerBill();
customerBill.IsSurepay = XmlBillParser.GetSurepayFlagFromBill(document);
customerBill.ServiceAddress = XmlBillParser.GetServiceAddress(requestSa, document);
customerBill.monthName = XmlBillParser.GetnillStatementDate(requestSa, xmlBill);
customerBill.EqCurlPlanBal = XmlBillParser.getEqualizerCurrentPlanBalance(document);
customerBill.EqPymntDue = XmlBillParser.getEqualizerPaymentDue(document);
customerBill.Service = GetServiceAccountUsageAndBillingDetail(requestSa, xmlBill, saDetailedPageNode);
response.Add(customerBill);
}
}
catch (Exception ex)
{
trace.Write(new InvalidOperationException(requestSa, ex));
}
return response;
}
Here is the method that checks if there is a node in the XML. I have changed the code so that is returns all the nodes. I had to change the type xmlNode to xmlNodeList because now its returning a collection of nodes. ****This is whats causing all the problems in my code in other places.***
public static xmlNode GetDetailPageSectionBySa(string sa, string statementXml)
{
XmlDocument document = new XmlDocument();
document.LoadXml(statementXml);
string requestSa = sa.PadLeft(9, '0');
string xpath = String.Format("//Para[IRBILGP_SA_SAA_ID_PRINT.SERVICE.ACCOUNT.STATMENT='{0}S{1}']/..", requestSa.Substring(0, 4), requestSa.Substring(4));
return document.SelectNodes(xpath);
//var nodes = document.SelectNodes(xpath);
// if(nodes.Count > 0) return nodes[nodes.Count - 1];
//if(!SaExistInBill(requestSa, statementXml)) return null;
//var node = GetDetailPageSectionByBillPrisminfoIndex(sa, statementXml);
//if (node != null) return node;
//return null;
}
So returning back to where it is called.. im getting an invalid arguement here
customerBill.Service = GetServiceAccountUsageAndBillingDetail(requestSA, xmlBill, saDetailedPageNode); because the parameter saDetailedPageNode is xmlNodeList now when it is expecting of type xmlNode. if i go to the method private static ServiceAddressBillDetail GetServiceAccountUsageAndBillingDetail(string requestSA, string xmlBill, XmlNode detailPageNode) which i added at the end of this code so you could see. If I change the parameter XmlNode detailPageNode to XmlNodeList detailPageNode which I have to do to fix the invalid arguement above, I get that detailPageNode.SelectNodes becomes invalid because xmlNodeList does not have SelectNodes as an extension method. I use this extention method a lot through this method. So I am getting a lot of errors.
var saDetailedPageNode = XmlBillParser.GetDetailPageSectionBySa(requestSa, xmlBill);
if (saDetailedPageNode == null) continue;
var customerBill = new CustomerBill();
customerBill.IsSurepay = XmlBillParser.GetSurepayFlagFromBill(document);
customerBill.ServiceAddress = XmlBillParser.GetServiceAddress(requestSa, document);
customerBill.monthName = XmlBillParser.GetnillStatementDate(requestSa, xmlBill);
customerBill.EqCurlPlanBal = XmlBillParser.getEqualizerCurrentPlanBalance(document);
customerBill.EqPymntDue = XmlBillParser.getEqualizerPaymentDue(document);
customerBill.Service = GetServiceAccountUsageAndBillingDetail(requestSa, xmlBill, saDetailedPageNode);
response.Add(customerBill);
}
}
catch (Exception ex)
{
trace.Write(new InvalidOperationException(requestSa, ex));
}
return response;
}
private static ServiceAddressBillDetail GetServiceAccountUsageAndBillingDetail(string requestSA, string xmlBill, XmlNode detailPageNode)
{
var saBillDetail = new ServiceAddressBillDetail();
saBillDetail.UsageServiceName = requestSA;
var meterReadEndXMLNodes = detailPageNode.SelectNodes("Usage_kWh_b");
if (meterReadEndXMLNodes.Count == 0)
{
meterReadEndXMLNodes = detailPageNode.SelectNodes("Usage_kWh_a");
}
if (meterReadEndXMLNodes.Count == 0)
{
meterReadEndXMLNodes = detailPageNode.SelectNodes("APSElec_kWh_b");
}
if (meterReadEndXMLNodes.Count == 0)
{
meterReadEndXMLNodes = detailPageNode.SelectNodes("APSElec_kWh_a");
}
var demandXMLNodes = detailPageNode.SelectNodes("Usage_kW_Total_Bold");
How can i fix my invalid arguments so that I can use xmlNodeList instead of xmlNode? is there a way to convert or cast? or is there another xml object I can use?
Since I am now returning multiple nodes. I know that I will need to loop through the customerBill portion. How can I do that without creating a new bill for every node? All the nodes in one xml need to be included in one bill.
From the code you've provided, the only part that needs to account for your refactor to XmlNodeList is GetServiceAccountUsageAndBillingDetail(), so you have two options:
Update GetServiceAccountUsageAndBillingDetail() to take in an XmlNodeList parameter instead and aggregate values inside that method to come up with your final ServiceAddressBillDetail object.
Loop through your XmlNode objects in the XmlNodeList and reconcile the different ServiceAddressBillDetail objects yourself.
Without details on what ServiceAddressBillDetail, I can only guess as to which is better, but I'd suggest using the first option.
private static ServiceAddressBillDetail GetServiceAccountUsageAndBillingDetail(
string requestSA,
string xmlBill,
XmlNodeList detailPageNodes)
{
var saBillDetail = new ServiceAddressBillDetail();
saBillDetail.UsageServiceName = requestSA;
foreach(XmlNode detailPageNode in detailPageNodes)
{
var meterReadEndXMLNodes = detailPageNode.SelectNodes("Usage_kWh_b");
if (meterReadEndXMLNodes.Count == 0)
{
meterReadEndXMLNodes = detailPageNode.SelectNodes("Usage_kWh_a");
}
if (meterReadEndXMLNodes.Count == 0)
{
meterReadEndXMLNodes = detailPageNode.SelectNodes("APSElec_kWh_b");
}
if (meterReadEndXMLNodes.Count == 0)
{
meterReadEndXMLNodes = detailPageNode.SelectNodes("APSElec_kWh_a");
}
var demandXMLNodes = detailPageNode.SelectNodes("Usage_kW_Total_Bold");
//Whatever comes next
}
}
Assuming ServiceAddressBillDetail has properties for "usage" you could simply add the appropriate values from each detailPageNode to the saBillDetail object.
It's hard to see what is going on but this may be the problem;
string xpath = String.Format("//Para..
The "//" will search in the entire document, but you probably want to search for descendent elements.
Here's some code to deal with a similar problem;
XmlNodeList staffNodes = resultXML.SelectNodes("//staff");
List<TempStaff> tempStaffs = staffNodes
.Cast<XmlNode>()
.Select(
i =>
new TempStaff()
{
StaffId = i.SelectSingleNode("id").InnerText,
Forename = i.SelectSingleNode("forename").InnerText,
Surname = i.SelectSingleNode("surname").InnerText,
}
).ToList();
My XML looks like
<staff><forename>asdf</forename><surname>ddsf</surname><id>123</id>... </staff>
<staff><forename>asdfas</forename><surname>asffdf</surname><id>456</id>...</staff>
I have some code that I need to put into a string list in C# and I am reading this code from an XML files and the layout of it is something like below...
<?xml version="1.0"?>
<accountlist>
<main>
<account id="1" special_id="4923959">
<username>Adam</username>
<motto>Hello Everyone>
<money>1004</money>
<friends>394</friends>
<rareid>9</rareid>
<mission>10</mission>
</account>
</main>
</accountlist>
How can I put each account tag into a string list? from the first < account > to the < / account > tag?
Please do NOT tell me to go to the link below as it does NOT work!!
How to read a XML file and write into List<>?
So far I have tried the below code, and the string list just stays empty
XDocument doc = XDocument.Parse(this._accountsFile);
List<string> list = doc.Root.Elements("account")
.Select(element => element.Value)
.ToList();
this._accounts = list;
You'll have to use Descendants instead of Elements:
List<string> list = doc.Root.Descendants("account").Descendants()
.Select(element => element.Value)
.ToList();
Elements only returns child elements of the element (in case of the root element this means <main>).
Descendants returns the entire tree inside the element.
Also: You'll have to fix the tag <motto>Hello Everyone> to <motto>Hello Everyone</motto>
This will work on your example (but you need to close this tag <motto>Hello Everyone>
public List<string> GetAccountsAsXmlList(string filePath)
{
XmlDocument x = new XmlDocument();
x.Load(filePath);
List<string> result = new List<string>();
XmlNode currentNode;
foreach (var accountNode in x.LastChild.FirstChild.ChildNodes)
{
currentNode = accountNode as XmlNode;
result.Add(currentNode.InnerXml);
}
return result;
}
EDIT as an answer to your question:
Is there a way I can get the id and specal_id in a seperate string?
you can use currentNode.Attributes["YourAttributeName"].Value, to get the values.
assume you have class Account :
class Account
{
public string accountXml { get; set; }
public string Id { get; set; }
public string Special_id { get; set; }
}
Then :
public List<Account> GetAccountsAsXmlList(string filePath)
{
XmlDocument x = new XmlDocument();
x.Load(filePath);
List<Account> result = new List<Account>();
XmlNode currentNode;
foreach (var accountNode in x.LastChild.FirstChild.ChildNodes)
{
currentNode = accountNode as XmlNode;
result.Add(new Account
{
accountXml = currentNode.InnerXml,
Id = currentNode.Attributes["id"].Value,
Special_id = currentNode.Attributes["special_id"].Value,
});
}
return result;
}
Use XPath to get the account element first:
using System.Xml.XPath;
XDocument doc = XDocument.Parse(xml);
foreach(var account in doc.XPathSelectElements("accountlist/main/account")){
List<string> list = account.Descendants()
.Select(element => element.Value)
.ToList();
}
Try this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication37
{
class Program
{
static void Main(string[] args)
{
string input =
"<?xml version=\"1.0\"?>" +
"<accountlist>" +
"<main>" +
"<account id=\"1\" special_id=\"4923959\">" +
"<username>Adam</username>" +
"<motto>" +
"Hello Everyone>" +
"<money>1004</money>" +
"<friends>394</friends>" +
"<rareid>9</rareid>" +
"<mission>10</mission>" +
"</motto>" +
"</account>" +
"</main>" +
"</accountlist>";
XDocument doc = XDocument.Parse(input);
var results = doc.Descendants("accountlist").Select(x => new {
id = x.Element("main").Element("account").Attribute("id").Value,
special_id = x.Element("main").Element("account").Attribute("special_id").Value,
username = x.Element("main").Element("account").Element("username").Value,
motto = x.Element("main").Element("account").Element("motto").FirstNode.ToString(),
money = x.Element("main").Element("account").Element("motto").Element("money").Value,
friends = x.Element("main").Element("account").Element("motto").Element("friends").Value,
rareid = x.Element("main").Element("account").Element("motto").Element("rareid").Value,
mission = x.Element("main").Element("account").Element("motto").Element("mission").Value,
}).ToList();
}
}
}
I am using the following code to get data from the OData XML and its works ,
but I am not sure that I fully understand it so maybe there is a way to write it in simple way?
what i need is to get the property value which is in the first loop value = 0001 and text = approve and in the
second value = 0002 text = reject
The code
XNamespace dns = "http://schemas.microsoft.com/ado/2007/08/dataservices";
if (response.StatusCode == HttpStatusCode.OK)
{
string decisionOptions = ReadResponse(response);
XDocument document = XDocument.Parse(decisionOptions);
foreach (XElement element in document.Element(dns + "DecisionOptions").Elements(dns + "element"))
{
PropertyKeyRef decisionOption = new PropertyKeyRef();
decisionOption.PropertyValue = element.Element(dns + "DecisionKey").Value;
decisionOption.PropertyName = element.Element(dns + "DecisionText").Value;
dat.Add(decisionOption);
}
}
the XML
<?xml version="1.0" encoding="utf-8" ?>
- <d:DecisionOptions xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">

here how can do it in simple way using LINQ
namespace ConsoleApplication7
{
class Program
{
static void Main(string[] args)
{
XDocument xdoc = XDocument.Load("test.xml");
XNamespace dns = "http://schemas.microsoft.com/ado/2007/08/dataservices";
//in xml every element should have it's namespace for this reason I have to concatenate namespace with the name of element
var elementsRes = xdoc.Root.Elements(dns+"element").Select((elt) => new PropertyKeyRef { PropertyName = elt.Element(dns+"DecisionKey").Value.ToString(),PropertyValue = elt.Element(dns+"DecisionText").Value.ToString() }).ToList();
foreach (var item in elementsRes)
{
//your code for the result
}
}
}
public class PropertyKeyRef
{
public string PropertyName
{ get; set; }
public string PropertyValue
{ get; set; }
}
}
You have already achieved it in simplest way. Little bit of LINQ might improve readability (get away with foreach loop) but it's just syntactic sugar of what you have written.
XNamespace dns = "http://schemas.microsoft.com/ado/2007/08/dataservices";
XDocument document = XDocument.Load("database.xml");
PropertyKeyRef decisionOption = new PropertyKeyRef();
decisionOption.PropertyValue = document.Descendants(dns + "DecisionKey")
.Select(node => node.Value).First();
decisionOption.PropertyName = document.Descendants(dns + "DecisionText")
.Select(node => node.Value).First();
dat.Add(decisionOption);
I am trying to take an XML file containing multiple orders from an online shopping cart, parse it and output the values of each order as its own text file (not XML) using C# and Visual Studio 2008. I have tried a variety of methods at this point, but have had no luck. My last attempted included a foreach statement tied to XMLNodeList and trying to execute my translation for each node with the name "Order" by using XMLReader to write each elements value to a string. The foreach seems to be what is not working with the current configuration.
Is there a better way to do this or do I need to keep using a foreach? All thoughts are greatly appreciated.

You can make this super simple. Object oriented programming is the way to go.
So say you create a class Order that takes an XElement. I'll write a couple lines for you.
public class Order
{
XElement self;
public Order(XElement order)
{
self = order;
}
public XElement Element { get { return self; } }
public string OrderNumber
{
// if your xml looks like <Order OrderNumber="somenumber" />
get { return (string)(self.Attribute("OrderNumber") ?? (object)"some default value/null"); }
// but if it looks like: <Order><OrderNumber>somenumber</OrderNumber></Order>
// get { return (string)(self.Element("OrderNumber") ?? (object)"some default value/null"); }
}
}
You'll have to fill in the rest of the Order's properties yourself. For each Order value, make a property like the OrderNumber I made above. Having properties for each Order value makes accessing the data super simple.
So for your main code you'd have:
XElement file = XElement.Load(#"C:\onlinesales\neworders.xml");
Order[] orders = file.Elements("Order").Select(e => new Order(e)).ToArray();
Now that you have all your orders as individual Order objects, read the data from the list of properties as you output to the file. There's no need now to store the values in StringBuilder's because the values are in the Order objects.
foreach(Order order in orders)
{
// write order.OrderNumber etc. / do whatever you want with the orders.
}
Chuck has a good approach. Sometimes, you don't want to retain the reference to the underlying xml data structure in the model object you are loading. In this case, I often use a pattern like this:
public interface IXmlReadable
{
void Clear();
void Read(XPathNavigator xmlNav);
}
public class ModelBase : IXmlReadable
{
public void Clear()
{
DoClear();
}
public void Read(XPathNavigator xmlNav)
{
DoRead(xmlNav);
}
protected virtual void DoClear()
{
throw new NotImplementedException();
}
protected virtual void DoRead(XPathNavigator xmlNav)
{
throw new NotImplementedException();
}
}
Read can be overloaded to accept XmlDocument, XmlNode, XElement, etc.
Now you can implement specific models.
public sealed class Order : ModelBase
{
public Order() { }
public string OrderNumber { get; private set; }
protected override void DoClear()
{
OrderNumber = string.Empty;
}
protected override void DoRead(XPathNavigator xmlNav)
{
DoClear();
XPathNavigator node;
node = xmlNav.SelectSingleNode("OrderNumber");
if (node != null)
OrderNumber = node.InnerXml;
// implement other properties here
}
}
With the XPathDocument and XPathNavigator approach, you can then do something like this:
XPathDocument xml = new XPathDocument(#"C:\onlinesales\neworders.xml");
xmlNav = xml.CreateNavigator();
XPathNodeIterator iterator = xmlNav.Select("Order");
while (iterator.MoveNext())
{
Order order = new Order();
order.Read(iterator.Current);
// do something with the Order - add to list or process
}
