Re: [xsl] building hierarchy from path string

Thanks much!  This gives me a good place to start.

I'd like to be able to handle path stings of arbitrary depth, so I'll 
try to modify your template to handle it. One approach would be to have 
a style sheet that generates another based on one look at the path. The 
two variables I must be perpared to handle are: (1) each level of depth 
is represented by a number of fixed within tree, but which may vary from 
tree to tree. (2) each tree has a specified depth which maybe obtained 
by dividing the path the by the number of characters representing each 
level. The path will always be the same length with in the tree, and (as 
you aptly detected) zeros always indicate that node is a parent for a 
given level. BTW this is a handy way to store & manipulate hierarchical 
data in a database--everybody's worst nightmare :).

I could pass the the info to the stylesheet by writing my xml this way:

<tree>
    <descriptor chars-per-tier="2" depth="3" />
    <node-list>
        <node depth="0" OID="1" name="Animals" path="100000" />
        <node depth="1" OID="2" name="Reptile" path="102000" />
        <node depth="2" OID="5" name="Snake" path="102010" />
        <node depth="2" OID="6" name="Crock" path="102020" />
        <node depth="2" OID="7" name="Gator" path="102030" />
        <node depth="1" OID="3" name="Bird" path="103000" />
        <node depth="1" OID="4" name="Mamal" path="103000" />
    </node-list>
</tree>

Thanks again, Joshua, for pointing me in the right direction with all of 
this. I'll crunch on it some and let you know what I come up with. 
Others--feel free to chime in!
