Hi List,
This should be a really easy thing to do, I'm sure, but I'm having a
blank spot today when it comes to XSLT, it seems. Perhaps some
imperative twist in my mind stops me from writing down a straight
solution (or I just never encountered the problem before, but I couldn't
find it in my own archive).
Basically, I have the solution, but it is so awkward that I am sure that
"there is a better way", esp. with XSLT. Take the dataset (see variable
$copy-me in the XSLT sample) and consider a copy of the Document node
for each Make-Toute-Seul-X node, without the other Make-Toute-Seul-X
nodes. The result of the transformation is this (see the similar data,
with changing Make-Toute-Seul-X elements):
(The original data is a SOAP envelope, and the envelope needs to be
copied a couple of times for each occurrence of some node, which
triggers a document in 'real' life)
OUTPUT:
<Header>
<Meta/>
</Header>
<Body>
<Document>
<Preceding-1/>
<Preceding-2/>
<Make-Toute-Seul-1/>
<Following-1/>
<Following-2/>
</Document>
<Document>
<Preceding-1/>
<Preceding-2/>
<Make-Toute-Seul-2/>
<Following-1/>
<Following-2/>
</Document>
<Document>
<Preceding-1/>
<Preceding-2/>
<Make-Toute-Seul-3/>
<Following-1/>
<Following-2/>
</Document>
</Body>
The XSLT looks like this and can be run on itself (I had other
incarnations, equally bad, anybody with a nicer solution that feels more
like 'XSLT'?). I'd like to move the duplicated logic about the nodes
Make-Toute-Seul-X to a single location, to make maintenance a breeze.
<xsl:stylesheet

Thanks for any help,
