Actually I can reduce my question to the following: Assuming I have a
variable which stores a node-tree like that
let $tree :=
In reality $tree is the entire XML file which I want to send back to the
client. Now, depending on some conditions I want to change the content
of <subnode> "some text" to "some other text", before sending it. I
don't actually want to alter the file in the database, just the message
that I'm sending.
If I placed the XML-file inside the script, I would write something like
then "some text"
else "some other text"
But since I have a couple of not too small XML files I fear that this
will get a bit overcrwoded.
Do you understand what I mean?
