RE: [xsl] xslt for hierarchical data

[omprakash.v@xxxxxxxxxxxxx]

Hi Jody,

        I would think that the best way to solve your problem would be to
use a 2-phase transformation. You first create a nodeset that way you have
the  hierarchical relationship readily available.


Thus your xml becomes,

<records>
<record id="1" name="Jack">

<record id="1" name="Jack Jr">
<record id="7" name="Jack III"/>
</record>

<record id="4" name="William">
<record id="3" name="William Jr.">
<record id="3" name="William III">
<record id="3" name="William IV"/>
</record>
</record>
</record>

</record>
</records>

and in the second phase you emit the result with the elements correctly
intendeted. Ofcourse to do this in XSLT 1.0, you would need the nodeset
extension function.

Hope this helps.

cheers,
prakash

Sample code would be extremely helpful.

I gave you an answer to this question when you asked it on xml-dev. Did you
have difficulties with that answer? If so, please explain what you didn't
understand and I will try to explain in more detail.
