Well after digging a little bit more in my brain and my code snippet
treasure chest I found that I originally read this code in the
ActiveWidget support forum.
So I asked Alex (the author) if I can use the (rewritten and modified)
code part for donating it to a LGPL project and he allowed it. Here is
my post in the support forum:
http://www.activewidgets.com/javascript.forum.9267.4/question-on-reusing-code-of.html
And of course after digging a little bit more on this I found some
improvements and a hint that the syntax with the getter modifier for the
function is deprecated (the .__getter__ method should be used). So here
is the latest and greatest diff:
After having a detailed look at the XPathEvaluator implementation of
mozilla/gecko and the getter/setter interface I think we can asume that
this is common knowledge and nothing worth to be copyrighted.
wow cool. I have just committed your patch to CVS.

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
