Steps to Reproduce Behavior

1. Create a sample XML file:
   1. Create a new text document by using Windows Notepad or another text editor.
   2. Paste the following code into the new text document:

       <?xml version="1.0"?>
          <books>
          <book>
            <title>XML Step by Step</title>
          </book>
          <book>
            <title>Developing XML Solutions</title>
          </book>
         </books>
      						

   3. Save the file as Books.xml in the home folder of your default Web site (this is typically C:\InetPub\WWWRoot).
2. Create a sample Windows script:
   1. Create a new text document by using Windows Notepad or another text editor.
   2. Paste the following code into the new text document:

       var xmlDoc = new ActiveXObject("msxml2.domdocument");
       xmlDoc.async = false;
       xmlDoc.load("http://localhost/books.xml");
      
       xmlDoc.setProperty("SelectionLanguage", "XPath");
       xmlDoc.setProperty("SelectionNamespaces", "xmlns:my='urn:http//www.my.com/schema/'");
       var nodelist = xmlDoc.documentElement.selectNodes("child::my:book");
      
       var stExpected = "xmlns:my='urn:http//www.my.com/schema/'";
       var stActual;
       try
        {
          stActual = nodelist.getProperty("SelectionNamespaces");
        }
       catch(e)
        {
         WScript.Echo("Should not have an error:" + e.number + e.description);
        }
      		
        WScript.Echo(stExpected==stActual);
      						

   3. Save the document as C:\getProperty.js.
3. At a command prompt, execute the script by using the following command:
   cscript C:\getProperty.JS

You receive the "Property name is invalid" error message.
