XPath problem with selectSingleNode in MSXML4

[John Sands <wonkowatson@yahoo.com>]

I have a file called config.xml like this:

 <?xml version="1.0"?>
 <config>
  <link href="tree.asp"/>
  <link href="search.asp" default="true" />
 </config>

This Javascript ASP code finds the href with the "default=true" attribute:

 var xmldoc = new ActiveXObject("MSXML2.DOMDocument.4.0");
 xmldoc.async = false;
 xmldoc.load(Server.MapPath("config.xml"));
 xmldoc.setProperty("SelectionLanguage", "XPath");
 var defaultpage = xmldoc.selectSingleNode("/config/link[@default]");
 var href = defaultpage.getAttribute("href");

My question is, why doesn't this code find it as well?

 var xmldoc = new ActiveXObject("MSXML2.DOMDocument.4.0");
 xmldoc.async = false;
 xmldoc.load(Server.MapPath("config.xml"));
 xmldoc.setProperty("SelectionLanguage", "XPath");
 var href = xmldoc.selectSingleNode("/config/link[@default]/@href");

Thanks,
John Sands
