Hello,

Maybe it's just basics but how I can select node using attribute value. This is my XML loaded to XmlDocument:

<?xml version="1.0" encoding="utf-8"?>
<ConfigTree>
  <root label="C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Config\web.config" inherents="false">
    <node label="C:" inherents="false">
      <node label="inetpub" inherents="false">
        <node label="BlogEngine.NET" inherents="false">
          <node label="Web.Config" inherents="false" />
          <node label="Account" inherents="false">
            <node label="Web.Config" inherents="false" />
          </node>
          <node label="admin" inherents="false">
            <node label="Web.Config" inherents="false" />
            <node label="Comments" inherents="false">
              <node label="Web.Config" inherents="false" />
            </node>
            <node label="Pages" inherents="false">
              <node label="Web.Config" inherents="false" />
            </node>
            <node label="Users" inherents="false">
              <node label="Web.Config" inherents="false" />
            </node>
          </node>
        </node>
      </node>
    </node>
  </root>
</ConfigTree>

Lets say I want to select the underlined node. I am aware of the full address of the file:

string path = "c:\\inetpub\\BlogEngine.NET\\admin\\Comments\\Web.config";

how I can select XmlNode represented by the path variable?

Here is how you access the XML DOM to get the specified node.

string xmlpath = "C:\\inetpub\\BlogEngine.NET\\admin\\comments\\web.config";
XmlDocument d = new XmlDocument();
d.Load(xmlpath);
if (d.DocumentElement != null)
            {
                XmlNode node = d.DocumentElement.SelectSingleNode("//node[@label='Comments']/node[@label='Web.Config']");
                if (node != null)
                {
                   //Process the node 
                }
            }
