Hi Joris,
thank you very much for your confirmation.
I have tried to combine our code, but I get still stuck at using the
variable which should hold the tree/tree fragment or whatever this is
called correctly. Using the variable in the select part of an
apply-templates element leads to the following error (in debug mode,
menas xmlspy processor):
"Cannot use result tree fragmentError in Xpath expression, Cannot use
result tree fragment"
Using MSXML4 I get:
"Expression must evaluate to a node-set
->$vOrgaTree<- "
I tried to get some answers by the debugger (xpath evaluation after
break) gambling with $vOrgaTree/* , $vOrgaTree/self::* ...
I have also tried to add a top element(to make the tree well formed in
sense of xml)
But all this never lead to a good result !!!
I think my basic understanding of node-set and result tree fragment is
still zero.
Please find below my xslt trial (combined code from both of us)
Thanks a lot for your help
(I feel still like a very beginner in xslt as you see)

Hi again,
I tried the snipet below with XMLSpy (ALTOVA). In debug mode the
result of the variable is shown as Caption="169" Box="" Box="" Box=""
Box="" Box="" Box="" Box="" Which indicates that the tree is not build
correctly.
What I'm doing wrong ?
Your code generates a variable with exactly the tree you want.
(using altovaxslt.exe). The only explaination I can see, is that the
debug mode of XMLSpy doesn't show the exact XML-tree but rather a more
textual representation. The 'Box' elements contain no text-nodes, so
the debugger might indicate that with 'Box=""' . Perhaps you can
change some configurations of the program to see the XML-tree.
You could try the 'box' template in my 2nd mail to test if the variable contains the right xml-tree. (the case of the element names should be updated).
May be my idea to create a tree in a variable and then process it is
bad at all.
Off course it's not bad. With 'document fragment node' (in my first mail) I actually meant using a variable to store the 'pre-processed xml tree'.
Don't hesitate to post further questions or remarks.
regards,
