Yes i had read your link and also http://xml.apache.org/xalan-c/extens...b.html#nodeset.
Could you please look into my post http://p2p.wrox.com/topic.asp?TOPIC_ID=72863 - How to group accordingly per tm, sp, sn, price, tax?

xalan extension function is necessary for my requirement to convert target tree part generated by (createAccessFeesGroupList) function into a source tree that can then be searched for using xpath. Like the same do you have any example...

Please consider this as higher priority.....
