Wow Wendell,
Thank you so much for your solution as well as your explanation.
It worked great.
I am still learning about xslt.
I purchased wrox xslt 2nd edition but it seems a bit too complicated for me.
I went through few basic books.
Can you suggest me any resources?
Again than you!

Jim,
Ken's solution is also a good one (assuming he wrote what he intended to
write in his untested code ;-). Note that he's optimized for performance on
the assumption the nodes are correctly ordered in the input. If they're
not, his solution will be slow on large datasets compared to mine, but it
has the advantage of not caring how many levels deep you have to go.
(Except for the output element naming bit: tricky, that. If you could name
them 'Level2Category' instead of 'LevelTwoCategory', etc., this problem
would go away).
Cheers,
Wendell

tring($code)]"
/>
</xsl:element>
</xsl:template>
following-sibling:: could be replaced with ../ if the order is not
guaranteed.
