Hello,
The following RDF models a hierarchical website of 7 nodes with a max
depth of 2.
I don't see any graph described in your xml document.
I would like to transform it into a text file containing
each path through the site, one per line, where a path is a space
delimited sequence of hyperlink labels from the root of the site to a
leaf.
Therefore, for the following RDF data, I'd like to produce:
--
a d
a e
b f
b g
c h
--
Can xslt realize this transformation?
It is not xslt that will create the transformation, but an XSLT
programmer.
The problem is challenging
because 1) the RDF data models a DAG (directed acyclic graph), due to
the presence of crosslinks, rather than just a tree, and 2) there is no
way to associate any node with its parents and therefore the processing
must proceed in a top-down, rather than bottom-up, fashion.
Seems quite straightforward to me -- especially if you explain the problem
properly.
Could you draw the graph and explain how its vertices and arcs are
specified in your xml document? What is the meaning of a "crosslink"?

Top-down
processing is generally convenient when things are nested, but they are
not in this case.
