Hi all
I'm trying to get my head around the following problem... I've got a doc
with the following structure:
<item>
<keywords>Chair, Sofa, Cabinet</keywords>
</item>
<item>
<keywords>Chair, Sofa</keywords>
</item>
<item>
<keywords>Cabinet</keywords>
</item>
<item>
<keywords>Chair</keywords>
</item>
What I need to get out of that is a list of unique keywords, eg:
<keyword>Cabinet</keyword>
<keyword>Chair</keyword>
<keyword>Sofa</keyword>
That's fine.
Anyone know how I can do this? I'm using XSL/XPath 1.0.
Oh. That makes it more long winded.
I would do this in two stages - the first is to create a nodeset of
words by processing each <keywords> element using a recursive named
template to get something like:
<word>Chair</word>
<word>Sofa</word>
Once you have stage 1 complete, use the node-set extension function of
your processor to turn the result-tree-fragment into a nodeset, then
use grouping to do a distinct on the values.
