[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: XSL Template Match using z:row attributes
 Thanks, that did it. However, it's not producing what I expected. Sorry
for my ignorance, but here's what I'd like to do:
I'm trying to build a heirarchy based on the @LEVEL attrbiute
in my input XML.
So, if my input xml is:
<rs:data>
<z:row LEVEL='1' CATEGORYNAME='Product 1' CATEGORYID='1' PARENTID='0'
/>
<z:row LEVEL='2' CATEGORYNAME='Department A' CATEGORYID='2'
PARENTID='1' />
<z:row LEVEL='2' CATEGORYNAME='Department B' CATEGORYID='3'
PARENTID='1' />
<z:row LEVEL='3' CATEGORYNAME='Prospect' CATEGORYID='5' PARENTID='4'
/>
<z:row LEVEL='4' CATEGORYNAME='Appointment' CATEGORYID='49'
PARENTID='5' />
</rs:data>
I want to create output that's something like this:
<div level=1>
Product 1
<div level=2>
Department A
</div>
<div level=2>
Department B
<div level=3>
Prospect
<div level=4>
Appointment
</div>
</div>
</div>
</div>
I realize that this would be easier if my imput data was already in a
traditional hierarchical format, but I'm using MS ADO XML output
format.
Any more ideas??
Thanks,
Mike =:-)
