I am able to present the data in the same format but the problem I
have now is that I have to assign a unique ID to these data.
What I would like is that the IDs generated at lower level should
contain the ID of parent node as well. For example :-
ID of AA = (ID of A + ID of AA)
ID of AAA = (ID of A + ID of AA + ID of AAA)
and so on.
Actually, if you wanted something similar to the strings "A", "AA",
"AB" etc. to be your ids, they'd be easy enough to generate with xsl:number:
<xsl:number count="*" from="/" level="multiple" format="A"/>
(When I test with Saxon it uses a "." delimiter so things come out
"A.B.A" ... which is good when you get past X, Y, Z and start on AA....)
But it sounds like you want something more ... complex? transparent? opaque?
Such ids as you describe can be easily generated by traversing the
ancestor node from each element you want to label. But often IDs are
over-engineered, and don't need (or even are better without) all the
information they're asked to carry. Many times the generate-id()
function is actually better (because it warrants nothing beyond the
uniqueness of the identifier within the current document).
Cheers,
