The latter code does find it as well. The following code works fine for
me 

 var xmldoc = new ActiveXObject("MSXML2.DOMDocument.4.0");
 xmldoc.async = false;   
 xmldoc.loadXML("<config><link href=\"tree.asp\"/><link
href=\"search.asp\" default=\"true\" /></config>");
 WScript.Echo(xmldoc.xml);  
 xmldoc.setProperty("SelectionLanguage", "XPath");
 var defaultpage = xmldoc.selectSingleNode("/config/link[@default]");
 var href = defaultpage.getAttribute("href");
 WScript.Echo("1: " + href);
 href = xmldoc.selectSingleNode("/config/link[@default]/@href");
 WScript.Echo("2: " + href.value);

when executed using Windows scripting host. The difference in behavior
is because getAttribute returns a string while selectSingleNode returns
an object.  

Hope this helps. 

PS: Ignore my prior offlist email, this is NOT a bug.
