How to count number of XML nodes that contain specific value

Question

I am looking for how to count the nodes in an XML file that contain a value of "No" as well as the total number of elements.

I have the element count working fine, but I am not sure of the logic to look inside the XML for a value to count.

To get the total count I am using:

    XmlDocument readDoc = new XmlDocument();
    readDoc.Load(MapPath("Results.xml"));
    int count = readDoc.SelectNodes("root/User").Count;
    lblResults.Text = count.ToString();

Below is my XML:

<?xml version="1.0" encoding="iso-8859-1"?>
<root>
  <User>
    <URL>http://www.example.com</URL>
    <JSEnabled>Yes</JSEnabled>
  </User>
  <User>
   <URL>http://www.example.com</URL>
   <JSEnabled>Yes</JSEnabled>
 </User>
 <User>
   <URL>http://www.example.com</URL>
   <JSEnabled>Yes</JSEnabled>
 </User>
 <User>
   <URL>http://www.example.com</URL>
   <JSEnabled>Yes</JSEnabled>
 </User>
 <User>
   <URL>http://www.example.com</URL>
   <JSEnabled>No</JSEnabled>
 </User>

Solution

XmlDocument readDoc = new XmlDocument();
readDoc.Load(MapPath("Results.xml"));
int count = readDoc.SelectNodes("root/User").Count;
lblResults.Text = count.ToString();
int NoCount = readDoc.SelectNodes("JSEnabled[. = \"No\"]").Count;
