The idea of implementing a getter for attributes, elements and
textnodes is from:

Yes, maybe here are some copyright glitches? :-( Maybe I have to
ask the authors. Please wait with applying the patch.
Sorry for the inconveniance.

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.
Is this patch usable to get committed to the qooxdoo cvs? What is
the copyright stuff of this lines?

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
