I have an XML file looking like this:
<data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<row>
<Alert>warning</Alert>
<Alert2>warning</Alert2>
</row>
</data>
When I use the code below I only get the "Alert"-node. But I wan't "Alert2" as well (and so on...). What am I missing here?
using (XmlReader reader = cmd.ExecuteXmlReader())
{
string xmlFile = "";
while (reader.Read())
{
xmlFile = reader.ReadOuterXml();
}
var doc = new XmlDocument();
doc.LoadXml(xmlFile);
var nodes = doc.SelectNodes("data/row");
if (nodes == null) return columns;
var i = 0;
foreach (XmlNode node in nodes)
{
var column = node.ChildNodes[i].Name;
columns.Add(column);
i++;
}
return columns;
}
Change your loop to the equivalent of:
var doc = new XmlDocument();
doc.LoadXml(xml);
var nodes = doc.SelectNodes("data/row");
int i = 0;
foreach (XmlNode node in nodes)
{
foreach (var child in node.ChildNodes)
{
var element = (XmlElement)child;
string nodeName = element.Name;
string value = element.InnerXml;
i++;
}
}

I have a XML file that looks like this:
<Info>
<ID>1</ID>
<Result>
<ID>2</ID>
</Result>
</Info>
I want to count how many Info/Result/ID I have in this file.
I am doing this:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("myFile.xml");
xmlNodeList MyList = xmlDoc.GetElementsByTagName("Info/Result/ID");
int totalCount = MyList.Count;
// other logic...
The method GetElementsByTagName does not find any "ID"-field.
I want to get the "ID = 2".
How do I do that?
To count all the nodes in "Info/Result/ID" path use this..
var count = xmlDoc.SelectNodes("Info/Result/ID")?.Count ?? 0;
To process these nodes
var nodes = xmlDoc.SelectNodes("Info/Result/ID");
foreach (XmlNode node in nodes) {
var idValue = node.InnerText
// do something
}
Got it working, here´s how:
public static void MyCountExample(string myXml, out int myID)
{
var stream = new MemoryStream(Encoding.UTF8.GetBytes(myXml ?? ""));
var reader = XmlReader.Create(stream);
myID= 0;
reader.IsStartElement("Info");
while (!reader.EOF)
{
if (reader.ReadToFollowing("Result"))
{
if (reader.ReadToDescendant("ID"))
{
myID++;
else
{
return somethingElse();
}
......
I have created a XML string and Looping that to get value. But its not entering in foreach loop. But in my other code same loop code is working.
my code is :
XML string:
<SuggestedReadings>

</SuggestedReadings>
Code Is:
string str = CD.SRList.Replace("&", "&");
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(str);
XmlNode SuggestionListNode = xmlDoc.SelectSingleNode("/SuggestedReadings/Suggestion");
foreach (XmlNode node in SuggestionListNode)
{
COURSESUGGESTEDREADING CSR = new COURSESUGGESTEDREADING();
var s = db.COURSESUGGESTEDREADINGS.OrderByDescending(o => o.SRID);
CSR.SRID = (s == null ? 0 : s.FirstOrDefault().SRID) + 1;
CSR.COURSEID = LibId;
CSR.TEXT = node.Attributes.GetNamedItem("Text").Value;
CSR.LINK = node.Attributes.GetNamedItem("Link").Value; ;
CSR.SUGBY = node.Attributes.GetNamedItem("SuggBy").Value; ;
CSR.ACTIVEFLAG = "Y";
CSR.CREATEDBY = CD.CreatedBy;
CSR.CREATEDDATE = DateTime.Now;
db.COURSESUGGESTEDREADINGS.Add(CSR);
}
You should use SelectNodes, not SelectSingleNode, since you are trying to get multiple rows out of the XML document.
Use this:
XmlNodeList SuggestionListNode = xmlDoc.SelectNodes("//Suggestion");
foreach (XmlNode node in SuggestionListNode)
{
}
You can try this.
XDocument xdoc = XDocument.Load("data.xml");
var xmlData = from lv1 in xdoc.Descendants("Suggestion")
select new {
Text = lv1.Attribute("Text").Value,
Link = lv1.Attribute("Link").Value,
SuggBy = lv1.Attribute("SuggBy").Value
};
foreach (var item in xmlData){
// your logic here
}
I need to store the element values which are inside the nodes "member" . I have tried the following code but I can't achieve it. How to get the values. Any help would be appreciated
XML:
<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">
<ListInventorySupplyResult>
<InventorySupplyList>
<member>
<SellerSKU>043859634910</SellerSKU>
<FNSKU>X000IA4045</FNSKU>
<ASIN>B005YV4DJO</ASIN>
<Condition>NewItem</Condition>
<TotalSupplyQuantity>7</TotalSupplyQuantity>
<InStockSupplyQuantity>7</InStockSupplyQuantity>
<EarliestAvailability>
<TimepointType>Immediately</TimepointType>
</EarliestAvailability>
<SupplyDetail>
</SupplyDetail>
</member>
</InventorySupplyList>
</ListInventorySupplyResult>
<ResponseMetadata>
<RequestId>58c9f4f4-6f60-496a-8d71-8fe99ce301c9</RequestId>
</ResponseMetadata>
</ListInventorySupplyResponse>
C# Code:
string a = Convert.ToString(oInventorySupplyRes.ToXML());
XmlDocument oXdoc = new XmlDocument();
oXdoc.LoadXml(a);
XmlNodeList oInventorySupplyListxml = oXdoc.SelectNodes("//member");
foreach (XmlNode itmXml in oInventorySupplyListxml)
{
// var cond = itmXml.InnerXml.ToString();
var asinVal = itmXml.SelectSingleNode("ASIN").Value;
var TotalSupplyQuantityVal = itmXml.SelectSingleNode("TotalSupplyQuantity").Value;
}
ResultView : "Enumeration yielded no results" and count = 0;
Edit 1:
string a = Convert.ToString(oInventorySupplyRes.ToXML());
var status = oInventorySupplyResult.InventorySupplyList;
XmlDocument oXdoc = new XmlDocument();
var doc = XDocument.Parse(a);
var r = doc.Descendants("member")
.Select(member => new
{
ASIN = member.Element("ASIN").Value,
TotalSupplyQuantity = member.Element("TotalSupplyQuantity").Value
});
private string mStrXMLStk = Application.StartupPath + "\\Path.xml";
private System.Xml.XmlDocument mXDoc = new XmlDocument();
mXDoc.Load(mStrXMLStk);
XmlNode XNode = mXDoc.SelectSingleNode("/ListInventorySupplyResult/InventorySupplyList/member");
if (XNode != null)
{
int IntChildCount = XNode.ChildNodes.Count;
for (int IntI = 1; IntI <= IntChildCount ; IntI++)
{
string LocalName = XNode.ChildNodes[IntI].LocalName;
XmlNode Node = mXDoc.SelectSingleNode("/Response/" + LocalName);
// Store Value in Array assign value by "Node.InnerText"
}
}
Try This Code. Its Worked
try using this xpath
string xPath ="ListInventorySupplyResponse/ListInventorySupplyResult
/InventorySupplyList/member"
XmlNodeList oInventorySupplyListxml = oXdoc.SelectNodes(xpath);
when you do "//member", then, the code is trying to look for element named member from the root level, which is not present at the root level, rather it is nested beneath few layers.
I think this will help you..
string a = Convert.ToString(oInventorySupplyRes.ToXML());
XmlDocument oXdoc = new XmlDocument();
oXdoc.LoadXml(a);
XmlNodeList fromselectors;
XmlNodeList toselectors;
XmlElement root = oXdoc.DocumentElement;
fromselectors = root.SelectNodes("ListInventorySupplyResult/InventorySupplyList/member/ASIN");
toselectors = root.SelectNodes("ListInventorySupplyResult/InventorySupplyList/member/TotalSupplyQuantity");
foreach (XmlNode m in fromselectors)
{
you will have value in `m.InnerXml` use it whereever you want..
}
foreach (XmlNode n in toselectors)
{
you will have value in `n.InnerXml` use it whereever you want..
}
I want to update the xml document and i need to return the updated xml in string. I am trying like below. when i save the document it expects the file name. but i dont want to save this as file. i just want to get the updated xml in string.
string OldXml = #"<Root>
<Childs>
<first>this is first</first>
<second>this is second </second>
</Childs
</Root>";
XmlDocument NewXml = new XmlDocument();
NewXml.LoadXml(OldXml );
XmlNode root = NewXml.DocumentElement;
XmlNodeList allnodes = root.SelectNodes("*");
foreach (XmlNode eachnode in allnodes)
{
if (eachnode.Name == "first")
{
eachnode.InnerText = "1";
}
}
NewXml.Save();
string newxml = NewXml.OuterXml;
You don't need to call Save method because string is immutable, your problem is in root.SelectNodes("*"), it just get child nodes, not all level of nodes. You need to go one more level:
foreach (XmlNode eachnode in allnodes)
{
var firstNode = eachnode.ChildNodes.Cast<XmlNode>()
.SingleOrDefault(node => node.Name == "first");
if (firstNode != null)
{
firstNode.InnerText = "1";
}
}
string newxml = NewXml.OuterXml;
It would be strongly recommended using LINQ to XML, it's simpler:
var xDoc = XDocument.Parse(OldXml);
foreach (var element in xDoc.Descendants("first"))
element.SetValue(1);
string newXml = xDoc.ToString();
Your iteration never reaches a node called "first". Else it would work fine without saving the NewXml.
You could however use a XElement and iterate over all descendants.
string OldXml = #"<Root>
<Childs>
<first>this is first</first>
<second>this is second </second>
</Childs>
</Root>";
var NewXml = XElement.Parse(OldXml);
foreach (var node in NewXml.Descendants())
{
if (node.Name.LocalName == "first")
{
node.Value = "1";
}
}
var reader = NewXml.CreateReader();
reader.MoveToContent();
string newxml = reader.ReadInnerXml();
I am trying to loop through an Xml file and display the value for account in a message.
XmlNodeList nodeList = testDoc.SelectNodes("/details/row/var");
foreach (XmlNode no in nodeList)
{
XmlNode node = testDoc.SelectSingleNode("/details/row/var[#name='account']");
test.actual = node.Attributes["value"].Value;
MessageBox.Show(test.account);
}
The message box is currently displaying the first record repeatidly, how can I get to the next record?
Thanks for your input in advance.
You are repeatedly assigning node with the same element from testDoc. It is not clear what test.account is (perhaps a mistype for test.actual)?
no is the variable which will iterate the contents of nodeList - I imagine you intended to use that.
EDIT following edit of OP
Now you've shown us what nodeList is, I suspect you want to do something like this instead :
XmlNodeList nodeList = testDoc.SelectNodes("/details/row/var[#name='account']");
foreach (XmlNode no in nodeList)
{
test.actual = no.Attributes["value"].Value;
...
XmlDocument doc = new XmlDocument();
doc.Load("d:\\test.xml");
XmlNodeList node = doc.GetElementsByTagName("w:r");
foreach (XmlNode xn in node)
{
try
{
if (xn["w:t"].InnerText != null)
{
if (xn["w:t"].InnerText == "#")
{
string placeHolder = xn["w:t"].InnerText;
foreach (XmlNode a in node)
{
if (a["w:t"].InnerText != "#")
{
string placeHolder1 = a["w:t"].InnerText;
}
}
}
}
}
catch (Exception e)
{
Console.Write(e);
}
}
Here is the sample for parent node value to get information of the child nodes.here i am using the ReportItems ParentNode and Print only image child nodes.
xmldoc.Load(rdlFile);
StringBuilder sb=new StringBuilder();
XmlNode node = xmldoc.GetElementsByTagName("ReportItems")[0];
XmlNodeList list = node.ChildNodes;
atributes=new string[node.ChildNodes.Count];
int l = 0;
for (int j = 0; j < node.ChildNodes.Count; j++)
{
if (list[j].Name == "Image")
{
XmlAttributeCollection att = list[j].Attributes;
atributes[l] = att[0].Value.ToUpper();
}
l++;
}
for (int i = 0; i < node.ChildNodes.Count; i++)
{
if (searchText.Text.ToUpper() == atributes[i])
{
XmlNodeList lastlist = node.ChildNodes;
XmlNodeList endlist = lastlist[i].ChildNodes;
for (int k = 0; k < endlist.Count; k++)
{
sb.Append(endlist[k].Name+" - "+ endlist[k].InnerText);
sb.Append("\n"+"\n");
}
}
}
let me know if you have doubt..
Try this,
XmlDocument xdoc = new XDocument();
xdoc.Load("*/File/*");
string xmlcontents = xdoc.InnerXml;
var xpath = "(/details/row/var[#name='account'])";
XmlNodeList lists = xdoc.DocumentElement.SelectNodes(xpath);
foreach (XmlNode _node in lists)
{
string _nodeValue = _node.InnerText;
MessageBox.Show(_nodeValue);
}
Try the following:
//Create an xml reader;
XmlDocument _xmlDocument = new XmlDocument();
_xmlDocument.Load(/*File Name here*/);
//Select the element with in the xml you wish to extract;
XmlNodeList _nodeList = _xmlDocument.SelectNodes("/details/row/var[#name='account']");
//Display the values in the node list to the screen;
foreach (XmlNode _node in _nodeList)
{
String _nodeValue = _node.InnerText.ToString();
MessageBox.Show(_nodeValue.ToString());
}
I'm not 100% sure, but you may need to use recursion. If not, it should just look like this:
XmlDocument doc = //etc..
foreach(XmlNode node in doc.ChildNodes)
{
if(node.Name == "account")
{
MessageBox.Show(node.Value);
}
}
You shouldn't spend time with reading the xml node by node. Try Deserialization:
