Question

i have a xml like following one.

  <testing>
  <node01 name="node01Name">
    <node02s>
      <node02 name="1">
        <CustomProperties>
          <CustomProperty Name="ASCII File Name" Value="index.txt" FilterID="0" />
          <CustomProperty Name="ASCII Folder" Value="\\abc\cdf\aaaa" FilterID="0" />
          <CustomProperty Name="Delimiter" Value="CommaQuote" FilterID="0" />
          <CustomProperty Name="Duplicate Handling" Value="Replace if Dup" FilterID="0" />
          <CustomProperty Name="EMAILATTDOC" Value="1" FilterID="0" />
          <CustomProperty Name="EMAILATTINDEX" Value="0" FilterID="0" />
          <CustomProperty Name="EMAILOUTBODY" FilterID="0" />
          <CustomProperty Name="EMAILOUTCC" FilterID="0" />
        </CustomProperties>
      </node02>
      <node02 name="2">
        <CustomProperties>
          <CustomProperty Name="ASCII File Name" Value="index.txt" FilterID="0" />
          <CustomProperty Name="ASCII Folder" Value="\\abc\cdf\aaaa" FilterID="0" />
          <CustomProperty Name="Delimiter" Value="CommaQuote" FilterID="0" />
          <CustomProperty Name="Duplicate Handling" Value="Replace if Dup" FilterID="0" />
          <CustomProperty Name="EMAILATTDOC" Value="1" FilterID="0" />
          <CustomProperty Name="EMAILATTINDEX" Value="0" FilterID="0" />
          <CustomProperty Name="EMAILOUTBODY" FilterID="0" />
          <CustomProperty Name="EMAILOUTCC" FilterID="0" />
        </CustomProperties>
      </node02>
    </node02s>    
  </node01>  
</testing>

I need to get each CustomProperty under each node02. this is my code.

XDocument configparentXML = XDocument.Load("admin.xml");
string node = "node02";

var batchClasses = from batchClasse in configparentXML.Descendants(node)
                   select new ReadingXmlWithLinq
                   {
                       BatchClassName = batchClasse.Attribute("Name") != null ? batchClasse.Attribute("Name").Value : "",
                   };

foreach (var lv0 in batchClasses)
{
    node = "CustomProperty";
    var CustomProperties = from CustomProperty in configparentXML.Descendants(node)                                       
                           select new ReadingXmlWithLinq
                           {
                               CustomPropertyName = documentClasse.Attribute("Name") != null ? documentClasse.Attribute("Name").Value : ""
                           };
}

But in hear its return all CustomPropery Values. How can i get CustomerPropery for a node02 ?

Thank you very much.

I’d approach this with XPath:

var xmlString = @"<testing>...</testing>";
var doc = XDocument.Parse(xmlString);
var nav = doc.CreateNavigator();
var path = "/testing/node01/node02s/node02/CustomProperties/CustomProperty";
var nodeIterator = nav.Select(path);
var nodes =
    nodeIterator
        .Cast<XPathNavigator>()
        .Select(n=>XElement.Parse(n.OuterXml));

EDIT

To get all nodes under (say) <node02 name="2"> you could alter the path as follows:

var path=
   "/testing/node01/node02s/node02[@name=2]/CustomProperties/CustomProperty";

Here’s a page of XPath examples so you can see what’s possible.
