No, parseXML just returns blahblah, so in effect I'd have just parsed some crazy string to come up with me = blahblah. It is written that way so that 'me' is given the properties stated above.
e:
PHP Code:
function parseXML(strXML) {

Some bug fixes:
- The xml declaration looks for the '?>' closing tag.
- Quotes next to the closing tag are removed.
- attributes can contain '>' now.
Some additions:
- Error messages.
- XML.nodeType now works for all nodes (I had originally scripted it to be XML.type and some of the .type code was still there. They were also never read-only at all, it seems.
