Here is a better patch which does not acces the text property/attribute
of nodes but implements getter methods for the text property:
This is a diff against QxXmlExtras.js in cvs renderer branch.

Hello List!
if someone needs this: Gecko/Mozilla has no implementation of the
simple to handle xpath node selection methods selectNodes and
selectSingleNode (which are InternetExplorerer proprietary) for
Element and Document object. Here is the Implementation built as patch
for QxXmlExtras.
A little tutorial for the usage is:
selectNodes: http://www.webreference.com/js/tips/020309.html
selectSingleNode: http://www.webreference.com/js/tips/020310.html
