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.
