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
