I have an XML file that I am parsing through and have come across a specific element that has it's own child nodes. The XML file is below:
<status.AppleSettings>
<AppleInstance MaxCost="250" Status="77" NewMode="5" SharePrice="350"
FlagTF="False" TimeClock="0" TimeClockSec="14"
Options="7532890" ID="JK_7755" Owner="SLP90"
Server="PA.SL90.COL" Name="SLP90" GroupName="COL.PA"
Instance="AppleServiceInstance" NewFlag="True" FinalCount="0"/>
<AppleInstance MaxCost="5" Status="0" NewMode="1" SharePrice="0"
FlagTF="False" TimeClock="300" TimeClockSec="1000"
Options="56794577431" Owner="A.CON" Instance="SL91"
NewFlag="True" FinalCount="1" List="1450, 1430"
Keyrepo="SYSTEMSERVER_7671902"/>
</status.AppleSettings>
As you can see, there's a parent node - AppleSettings and then two child nodes w/ the same name - AppleInstance. I created two separate classes for the child nodes since they have different attributes. I am able to access AppleSettings and when I do a quickwatch I can see the two child nodes inside, I just can't figure out how to access them. New to XML parsing and C# so everything is trial and error, learning a lot from stackoverflow.
Here is the code I have to access the AppleSettings parent node:
private List<Data> GetAppleSettingsNode(List<XmlDocument> XMLdocument, List<Data> DataList)
{
for (int i = 0; i < XMLdocument.Count(); i++)
{
AppleSettings temp = new AppleSettings();
var temp2 = XMLdocument[i].DocumentElement.SelectNodes("//AppleSettings");
foreach (var node in temp2)
{
var temp3 = node.ToString();
}
XmlNode xmlNode1 = XMLdocument[i].SelectSingleNode("//AppleSettings");
XmlSerializer serial1 = new XmlSerializer(typeof(AppleSettings));
temp = (AppleSettings)serial1.Deserialize(new XmlNodeReader(xmlNode1));
}
}
Is it even necessry to access the AppleSettings node? Could I go directly to the two AppleInstance child nodes? If someone could help me out, I'd appreciate it. Thanks!
It is better to use LINQ to XML API.
(1) The code below shows how to access any XML attribute by its name.
(2) .FirstOrDefault()?.Value technique will prevent exceptions generation when an attribute is missing.
c#
void Main()
{
const string FILENAME = #"e:\Temp\AppleSettings.xml";
XDocument doc = XDocument.Load(FILENAME);
foreach (var el in doc.Descendants("AppleInstance"))
{
Console.WriteLine("MaxCost={0}", el.Attributes("MaxCost").FirstOrDefault()?.Value);
Console.WriteLine("Instance={0}", el.Attributes("Instance").FirstOrDefault()?.Value);
Console.WriteLine("GroupName={0}", el.Attributes("GroupName").FirstOrDefault()?.Value);
}
}
Try following :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
namespace ConsoleApplication8
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XmlReader reader = XmlReader.Create(FILENAME);
XmlSerializer serializer = new XmlSerializer(typeof(Root));
Root root = (Root)serializer.Deserialize(reader);
}
}

The i of LargeXMLResponse[i] is loop count of the Large XML response if your response tag in wrapped up in between, and if you have a alternative way please go ahead with.
var ResponseToList = LargeXMLResponse[i].Descendants("Response").ToList();
if (ResponseToList.Count() > 0){
for (var pf = 0; pf < ResponseToList.Count(); pf++)
{
ResponseInfoList.Add(new ResponseToList{
id = ResponseToList[pf].Descendants("Block").Attributes("id").Count() > 0 ?
ResponseToList[pf].Descendants("Block ").Attributes("id").First().Value : "",
});

I am trying to loop through an Xml file and display the value for type in a message.But my code is repeatedly giving he first record values.
Below is my XML
<Request deploymentMode="test">

<Comments>ConfirmedQuantity:65.000</Comments>
</ConfirmationStatus>
</ConfirmationItem>
</ConfirmationRequest>
</Request>
My Code is as below.
XmlNodeList xnList = xmlDoc.SelectNodes("//ConfirmationRequest/ConfirmationItem");
foreach (XmlNode xn in xnList)
{
OrderNumber = null;
LineNumber = 0;
Quantity = 0;
UnitOfMeasure = null;
DeliveryDate = null;
Type = null;
ConfirmationStatus_Quantity = 0;
ConfirmationStatus_Unitofmeasure = null;
LineitemComments_1 = null;
LineitemComments_2 = null;
LineitemComments_3 = null;
LineitemComments_4 = null;
LineitemComments_5 = null;
CreatedDate = null;
XmlNode orh = xmlDoc.SelectSingleNode("//Request/ConfirmationRequest/OrderReference");
OrderNumber = (orh.Attributes["orderID"].Value == null) ? null : orh.Attributes["orderID"].Value;
LineNumber = int.Parse(xn.Attributes[0].Value == null ? null : xn.Attributes[0].Value);
Quantity = Convert.ToDecimal(xn.Attributes[1].Value == null ? null : xn.Attributes[1].Value);
UnitOfMeasure = xn.SelectSingleNode("UnitOfMeasure").InnerText == null ? null : xn.SelectSingleNode("UnitOfMeasure").InnerText;
DeliveryDate = xn.SelectSingleNode("//Request/ConfirmationRequest/ConfirmationItem/ConfirmationStatus/#deliveryDate").InnerText == null ? null : xn.SelectSingleNode("//Request/ConfirmationRequest/ConfirmationItem/ConfirmationStatus/#deliveryDate").InnerText;
DeliveryDate = DeliveryDate.Substring(0, 10);
Type = xn.SelectSingleNode("//Request/ConfirmationRequest/ConfirmationItem/ConfirmationStatus/#type").InnerText == null ? null : xn.SelectSingleNode("//Request/ConfirmationRequest/ConfirmationItem/ConfirmationStatus/#type").InnerText;
}
In every iteration , i am getting almost all the values except the
ConfirmationStatus tag's attribute string DeliveryDate.
ConfirmationStatus tag's attribute string Type.
Delivery date and Type are not changing with every iteration.
Every loop i get below results.
Loop -1 : DeliveryDate : 2019-10-02T07:00:00+0200 , Type = rejected.
Loop -2 : DeliveryDate : 2019-10-02T07:00:00+0200 , Type = rejected.
Loop -3 : DeliveryDate : 2019-10-02T07:00:00+0200 , Type = rejected.
Loop -4 : DeliveryDate : 2019-10-02T07:00:00+0200 , Type = rejected.
Where you can see these values of type are different for each loop and there is no deliverydate for loop-1.
I looked around related solutions , couldn't find any.
ANSWER
Figured out where exactly i am making a mistake.
I should be using
**xn.SelectSingleNode("ConfirmationStatus/#deliveryDate").InnerText**
**xn.SelectSingleNode("ConfirmationStatus/#type").InnerText**
Instead of
xn.SelectSingleNode("//Request/ConfirmationRequest/ConfirmationItem/ConfirmationStatus/#deliveryDate").InnerText
xn.SelectSingleNode("//Request/ConfirmationRequest/ConfirmationItem/ConfirmationStatus/#type").InnerText
Above statement always goes to the first occurance , hence i am only getting same values. **
Not sure if i am making a mistake somewhere.
Pls suggest.
Thnks.

i have an application that has to deserialize an array of data wrapped in a "results" Root Object, using Netwonsoft.Json package from NuGet
The Json string is exactly this:
{"results":[{"Coin":"SBD","LP":0.000269,"PBV":-54.36,"MACD1M":true,"MACD30M":true,"MACD1H":true,"MACD1D":true},{"Coin":"XMR","LP":0.027135,"PBV":11.44,"MACD1M":true,"MACD30M":true,"MACD1H":true,"MACD1D":true}]}
This Json string is created from a Console App i made, i wanted it to look like this https://bittrex.com/Api/v2.0/pub/market/GetTicks?marketName=BTC-NEO&tickInterval=hour
My class looks like this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace WindowsFormsApp2
{
public class Result
{
public string Coins { get; set; }
public decimal LastPrice { get; set; }
public decimal PercentBuyVolume { get; set; }
}
public class RootObject
{
public List<Result> results { get; set; }
}
}
In the Main form i have a function to download from a URL that Json (i have XAMPP running Apache) and deserialize it in an array. And it looks like this:
private void DownloadBittrexData()
{
int PanelID = 0;
var Coin = new List<string>();
var LastPrice = new List<decimal>();
var PercentBuyVolume = new List<decimal>();
var MACD1M = new List<bool>();
var MACD30M = new List<bool>();
var MACD1H = new List<bool>();
var MACD1D = new List<bool>();
var client = new WebClient();
var URL = client.DownloadString("http://localhost/test.json");
Console.WriteLine("Json String from URL: " + URL);
var dataDeserialized = JsonConvert.DeserializeObject<RootObject>(URL);
foreach (var data in dataDeserialized.results)
{
Coin.Add(data.Coins);
LastPrice.Add(data.LastPrice);
PercentBuyVolume.Add(data.PercentBuyVolume);
}
int sizeOfArrayClose = Coin.Count - 1;
for (int i = 0; i <= sizeOfArrayClose; i++)
{
Console.WriteLine("Coin: " + Coin[i]);
Console.WriteLine("Lastprice: " + LastPrice[i]);
Console.WriteLine("PBV: " + PercentBuyVolume[i]);
}
}
Newtonsoft.Json is of course declared at the beginning of the form together with System.Net
using System.Net;
using Newtonsoft.Json;
The output looks like this:
Json String from URL: {"results":[{"Coin":"SBD","LP":0.000269,"PBV":-54.36,"MACD1M":true,"MACD30M":true,"MACD1H":true,"MACD1D":true},{"Coin":"XMR","LP":0.027135,"PBV":11.44,"MACD1M":true,"MACD30M":true,"MACD1H":true,"MACD1D":true}]}
Coin:
Lastprice: 0
PBV: 0
Coin:
Lastprice: 0
PBV: 0
It's like it fails to deserialize it after downloading it.
What should i do? Thank you very much.
Your property names don't map to the field names in the JSON. You could rename your C# properties to match the JSON, but it would make for unreadable downstream code.
Instead, you should map your properties (with nice, readable names) to the names that appear in the JSON, using JsonPropertyAttribute:
public class Result
{
public string Coin { get; set; } //didn't bother here: changed property name to Coin
[JsonProperty("LP")]
public decimal LastPrice { get; set; }
[JsonProperty("PBV")]
public decimal PercentBuyVolume { get; set; }
}
your model should be like this for deserialize json
public class Result
{
public string Coin { get; set; }
public double LP { get; set; }
public double PBV { get; set; }
public bool MACD1M { get; set; }
public bool MACD30M { get; set; }
public bool MACD1H { get; set; }
public bool MACD1D { get; set; }
}
public class RootObject
{
public List<Result> results { get; set; }
}
LastPrice and PercentBuyVolume are not available in your model that's the reason it's getting an error.
I tried your exact code on my system and I was able to retrieve the result as expected. Hope this helps, It's easy to understand.
Here is the main class
static void Main(string[] args)
{
RootObject configfile = LoadJson();
foreach (var tResult in configfile.results)
{
Console.WriteLine("Coin: " + tResult.Coin);
Console.WriteLine("Lastprice: " + tResult.LP);
Console.WriteLine("PBV: " + tResult.PBV);
}
Console.ReadLine();
}
LoadJson Function would be
private static RootObject LoadJson()
{
string json = "{\"results\":[{\"Coin\":\"SBD\",\"LP\":0.000269,\"PBV\":-54.36,\"MACD1M\":true,\"MACD30M\":true,\"MACD1H\":true,\"MACD1D\":true},{\"Coin\":\"XMR\",\"LP\":0.027135,\"PBV\":11.44,\"MACD1M\":true,\"MACD30M\":true,\"MACD1H\":true,\"MACD1D\":true}]}";
RootObject configs = Deserialize<RootObject>(json);
return configs;
}
and Deserialize function would be
private static T Deserialize<T>(string json)
{
T unsecureResult;
string _DateTypeFormat = "yyyy-MM-dd HH:mm:ss";
DataContractJsonSerializerSettings serializerSettings = new DataContractJsonSerializerSettings();
DataContractJsonSerializer serializer;
MemoryStream ms;
unsecureResult = default(T);
serializerSettings.DateTimeFormat = new System.Runtime.Serialization.DateTimeFormat(_DateTypeFormat);
serializer = new DataContractJsonSerializer(typeof(T));
ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
unsecureResult = (T)serializer.ReadObject(ms);
return unsecureResult;
}
and Now your Datamodel would be
public class Result
{
public string Coin { get; set; }
public double LP { get; set; }
public double PBV { get; set; }
public bool MACD1M { get; set; }
public bool MACD30M { get; set; }
public bool MACD1H { get; set; }
public bool MACD1D { get; set; }
}
public class RootObject
{
public List<Result> results { get; set; }
}
I'm trying to deserialize xml retrieved from a web service call
using (var client = new WebClient())
{
client.UseDefaultCredentials = true;
var content = client.DownloadString("call to service");
System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(List<NewCourseApply.Models.Education>));
using (TextReader textReader = new StringReader(content))
{
var e = (List<NewCourseApply.Models.Education>)serializer.Deserialize(textReader);
}
}
The xml returned from the service is:
<ArrayOfEducation xmlns="http://schemas.datacontract.org/2004/07/CovUni.Domain.Admissions" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><Education><_auditList xmlns="http://schemas.datacontract.org/2004/07/CovUni.Common.Base" xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays"/><_apCode>670104552</_apCode><_attendanceType>FT</_attendanceType><_educationId>1</_educationId><_establishmentDetails>test school</_establishmentDetails><_fromDate>2016-11-01T00:00:00</_fromDate><_toDate>2016-11-22T00:00:00</_toDate><_ucasSchoolCode/></Education></ArrayOfEducation>
My client side object is:
[Serializable]
public class Education
{
protected int _apCode;
protected int _educationId;
protected string _establishmentDetails;
protected string _ucasSchoolCode;
protected DateTime? _fromDate;
protected DateTime? _toDate;
protected string _attendanceType;
protected string _auditList;
public int ApCode
{ get { return _apCode;}
set { _apCode = value;} }
public int EducationId
{ get { return _educationId;}
set { _educationId = value;} }
public string EstablishmentDetails
{ get { return _establishmentDetails;}
set { _establishmentDetails = value;} }
public string UcasSchoolCode
{ get { return _ucasSchoolCode;}
set { _ucasSchoolCode = value;} }
public DateTime? FromDate
{ get { return _fromDate;}
set { _fromDate = value;} }
public DateTime? ToDate
{ get { return _toDate;}
set { _toDate = value;} }
public string AttendanceType
{ get { return _attendanceType;}
set { _attendanceType = value;} }
public string AuditList
{ get { return _auditList;}
set { _auditList = value;} }
}
The error I am getting is:
There is an error in XML document (1, 2).
<ArrayOfEducation xmlns='http://schemas.datacontract.org/2004/07/CovUni.Domain.Admissions'> was not expected.
Also if I call a web service call and get the singular Education response i.e.:
<Education xmlns="http://schemas.datacontract.org/2004/07/CovUni.Domain.Admissions" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><_auditList xmlns="http://schemas.datacontract.org/2004/07/CovUni.Common.Base" xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays"/><_apCode>670104552</_apCode><_attendanceType>FT</_attendanceType><_educationId>1</_educationId><_establishmentDetails>test school</_establishmentDetails><_fromDate>2016-11-01T00:00:00</_fromDate><_toDate>2016-11-22T00:00:00</_toDate><_ucasSchoolCode/></Education>
Surely I just need one Simple Education class on the client side that can deserialise from the 2 examples of xml i have provided i.e. array and non array
Can some of you kind souls let me know where i'm going wrong or if there's a better way of doing this?
Many Thanks
Change the Class to
[XmlRoot("ArrayOfEducation", Namespace = "http://schemas.datacontract.org/2004/07/CovUni.Domain.Admissions")]
public class ArrayOfEducation
{
[XmlElement("Education")]
public List<ContainerEducation> education { get; set; }
}
public class ContainerEducation
{
[XmlElement(ElementName = "_apCode")]
public int _apCode { get; set; }
[XmlElement(ElementName = "_educationId")]
public int _educationId { get; set; }
[XmlElement(ElementName = "_establishmentDetails")]
public string _establishmentDetails { get; set; }
[XmlElement(ElementName = "_ucasSchoolCode")]
public string _ucasSchoolCode { get; set; }
[XmlElement(ElementName = "_fromDate")]
public DateTime? _fromDate { get; set; }
[XmlElement(ElementName = "_toDate")]
public DateTime? _toDate { get; set; }
[XmlElement(ElementName = "_attendanceType")]
public string _attendanceType { get; set; }
[XmlElement(ElementName = "_auditList", Namespace = "http://schemas.datacontract.org/2004/07/CovUni.Common.Base")]
public string _auditList { get; set; }
}
And Deserialize below way. Now, when I run the code to deserialize your XML, I do get the objects filled nicely.
XmlSerializer mySerializer = new XmlSerializer(typeof(ArrayOfEducation));
using (TextReader textReader = new StringReader(content))
{
ArrayOfEducation arrEdu = (ArrayOfEducation)mySerializer.Deserialize(textReader);
}
Update as per your comment:
If you are sure that web service is going to send single Education then you need to change the class to
[XmlRoot("ArrayOfEducation", Namespace = "http://schemas.datacontract.org/2004/07/CovUni.Domain.Admissions")]
public class ArrayOfEducation
{
[XmlElement("Education")]
public ContainerEducation education { get; set; }
}
So, I have XML like this:
<tileset firstgid="1" name="simple_tiles" tilewidth="32" tileheight="32" tilecount="16" columns="8">
<image source="../Users/mkkek/Pictures/rpg/default_tiles_x.png" width="256" height="64"/>
</tileset>
When I'm at the tileset node, how can I access the image node and its source attribute? My code is as follows:
public void LoadMaps(ContentManager content)
{
Dictionary<string, string> mapsToLoad = InitMapsToLoad();
foreach (KeyValuePair<string, string> mapToLoad in mapsToLoad)
{
Map map = new Map();
map.Name = Path.GetFileNameWithoutExtension(mapToLoad.Value);
reader = XmlReader.Create("Content/" + mapToLoad.Value);
while(reader.Read())
{
if(reader.NodeType == XmlNodeType.Element)
{
switch(reader.Name)
{
case "tileset":
if(!Tilesets.Any(ts => ts.Name == reader.GetAttribute("name")))
{
// handling the image node here
}
break;
}
}
}
}
}
I usually prefer to use LINQ to XML because I find it's API to be much easier to use than XmlReader, a comparison between the technologies here.
If all you need is getting source attribute value from image element this can be achieved easily:
var doc = XDocument.Load("something.xml");
var root = doc.DocumentElement;
var imageElements = root.Elements("image").ToList();
foreach (var imageElement in imageElements)
{
var sourceAttribute = imageElement.Attribute("source");
var sourceValue = sourceAttribute.Value;
//do something with the source value...
}
More about basic queries in LINQ to XML here.
I will suggest to create some classes that represents the Xml structure, something like this :
[XmlRoot(ElementName = "image")]
public class Image
{
[XmlAttribute(AttributeName = "source")]
public string Source { get; set; }
[XmlAttribute(AttributeName = "width")]
public string Width { get; set; }
[XmlAttribute(AttributeName = "height")]
public string Height { get; set; }
}
[XmlRoot(ElementName = "tileset")]
public class Tileset
{
[XmlElement(ElementName = "image")]
public Image Image { get; set; }
[XmlAttribute(AttributeName = "firstgid")]
public string Firstgid { get; set; }
[XmlAttribute(AttributeName = "name")]
public string Name { get; set; }
[XmlAttribute(AttributeName = "tilewidth")]
public string Tilewidth { get; set; }
[XmlAttribute(AttributeName = "tileheight")]
public string Tileheight { get; set; }
[XmlAttribute(AttributeName = "tilecount")]
public string Tilecount { get; set; }
[XmlAttribute(AttributeName = "columns")]
public string Columns { get; set; }
}
Then In some Utility class add the following method:
public static T DeserializeFromXml<T>(string xml)
{
if (string.IsNullOrEmpty(xml))
{
return default(T);
}
var serializer = new XmlSerializer(typeof(T));
T entity;
using (XmlReader reader = XmlReader.Create(new StringReader(xml)))
{
entity = (T)serializer.Deserialize(reader);
}
return entity;
}
Now you will be able to access to the Image object using the following code:
Tileset tileset=DeserializeFromXml<Tileset>(yourXmlContent);
// now you can access the image from the tileset instance 'tileset.Image.Source'
You are almost done. Add this to your code.
// handling the image node here
if (reader.ReadToDescendant("image"))
{
string source = reader.GetAttribute("source");
}
I have one xml file and I want to generate custom list from that xml using Linq.
here is my code. But I am not getting any records.Here is my code.
public class TemplateSettings {
public string DecimalSeparator { get; set; }
public string ThousandSeparator { get; set; }
public string DateSeparator { get; set; }
public string TimeSeparator { get; set; }
}
XML Here
<TemplateSetting>
<DecimalSeparator>1</DecimalSeparator>
<ThousandSeparator>2</ThousandSeparator>
<DateSeparator>3</DateSeparator>
<TimeSeparator>4</TimeSeparator>
<DateFormat>dd/MM/yyyy</DateFormat>
<ValueDelimiter>tr</ValueDelimiter>
<QuoteCharacter>r</QuoteCharacter>
<IsHeader>False</IsHeader>
</TemplateSetting>
And my code to get object from xml is
var a = (from x in objTemplateMasterEAL.TemplatSettingsXML.Elements("TemplateSetting")
select new TemplateSettings()
{
DateFormat = (string)x.Element("DateFormat"),
DecimalSeparator = (string)x.Element("DecimalSeparator"),
ThousandSeparator = (string)x.Element("ThousandSeparator"),
DateSeparator = (string)x.Element("DateSeparator"),
TimeSeparator = (string)x.Element("TimeSeparator"),
QuoteCharacter = (string)x.Element("QuoteCharacter"),
ValueDelimiter = (string)x.Element("ValueDelimiter"),
IsHeaderLine = (bool)x.Element("IsHeader")
}).ToList<TemplateSettings>();
Can any one suggest me what is wrong here ?
If your goal is just to deserialize the XML to object you can simply use this:
class Program
{
static void Main(string[] args)
{
using (StreamReader reader = new StreamReader("Sample.xml"))
{
var serializer = new XmlSerializer(typeof(TemplateSetting));
var templateSetting = (TemplateSetting)serializer.Deserialize(reader);
}
}
}
[XmlRoot]
public class TemplateSetting
{
public string DecimalSeparator { get; set; }
public string ThousandSeparator { get; set; }
public string DateSeparator { get; set; }
public string TimeSeparator { get; set; }
}
I make only on one change and its working fine for me.
<TemplateSettings>
<TemplateSetting>
<DecimalSeparator>1</DecimalSeparator>
<ThousandSeparator>2</ThousandSeparator>
<DateSeparator>3</DateSeparator>
<TimeSeparator>4</TimeSeparator>
<DateFormat>dd/MM/yyyy</DateFormat>
<ValueDelimiter>tr</ValueDelimiter>
<QuoteCharacter>r</QuoteCharacter>
<IsHeader>False</IsHeader>
</TemplateSetting>
</TemplateSettings>
