Parsing XML with namespaces in IE.

With IE you use MSXML for XML DOM, it implements methods selectNodes and
selectSingleNod e for DOM documents and elements (or even nodes in
general). With MSXML 3 and later you can pass an XPath 1.0 expression to
those two methods to select nodes:
   var doc = new ActiveXObject(' Msxml2.DOMDocum ent.3.0');
   doc.async = false;
   if (doc.load('file .xml'))
   {
      // necessary for MSXML 3 first:
      doc.setProperty ('SelectionLang uage', 'XPath');
>
      // now bind prefixes to namespace URIs e.g.
      doc.setProperty ('SelectionName spaces',
'xmlns:pf1="htt p://example.com/ns1" xmlns:pf2="http ://example.org/ns2"');
>
      // and use those prefixes in XPath expresssions
      var nodeList = doc.selectNodes ('pf1:foo/pf1:bar/pf2:baz');
      // use nodeList here
   }

Thank you Martin for a helpful reply. I have now got IE reading the
XML thanks to your post.

JFTR: dhtml.js:_addEv entListener():3 which is

if (o && sEvent && isMethodType(fL istener) && fListener)

should be

if (o && sEvent && isMethodType(ty peof fListener) && fListener)

This bug is FIXED since version 0.9.4.200804232 1 (unreleased).

Good remarks, thanks.  I may have to refine my isMethod().

I have replaced it largely with isMethod() in dhtml.js (which is going tobe
renamed to dom.js or something like that -- existing URIs are still goingto
work).  However, there are some instances where I think isMethodType() is
still needed.

At the very least, those who wish to implement proper feature testing
should be aware of this issue.  It helps to avoid such train-of-
thought wrecks as this:

Indeed. Odd that hasn't been pulled by now. Everybody who reads it
has the same reaction. Well, most everybody. See today's posts on
the subject.

I have replaced it largely with isMethod() in dhtml.js (which is going to be
renamed to dom.js or something like that -- existing URIs are still going to
work). However, there are some instances where I think isMethodType() is
still needed.

Have you two wankers finished hijacking this thread?
