Hi,
Did you already look at grouping:

Subject: [xsl] transforming flat data to hierarchical data. Recursion??
I'm having the following structure in an XML file
...
<Pages>
<PAGE id="1">
...
<Next id="2"/>
</PAGE>
<PAGE id="2">
...
<Next id="3"/>
</PAGE>
<PAGE id="3">
...
</PAGE>
<PAGE id="4">
...
<Next id="5"/>
</PAGE>
<PAGE id="5">
...
</PAGE>
...
</Pages>
...
And need to get to the following
...
<Pages>
<PAGE id="1">
...
<Next>
<PAGE id="2">
...
<Next>
<PAGE id="3">
...
</PAGE>
</Next>
</PAGE>
</Next>
</PAGE>
<PAGE id="4">
...
<Next>
<PAGE id="5">
...
</PAGE>
</Next>
</PAGE>
</Pages>
...
I think I need to use recursion but I cannot get the output I want.
I tried replacing every /Next/@id with its matching element using a
xsl:key
on the PAGE elements based on id
but that only replaces on one level and since I don't know the lenght of
the
linked lists I cannot use this principle.
Does anybody have an idea how to solve this
I'm not really that familiar with xslt
Kind regards
Dave
