[xslt] XSLT patterns without transformations?

[Magnus Lie Hetland <magnus hetland org>]

Hi!

I'm writing an application that's building document trees, and I need
to use XSLT patterns (or something similar) so the user can specify
various predicate that apply (or not) to any given node in the tree.

In other words: I have a document tree, a predicate (in the form of a
string), and a node, and I want to check whether the predicate (e.g.,
an XSLT pattern) is true for the given node.

After realising that the xpath and pattern support in libxml probably
wasn't what I was looking for (the patterns there are a bit too
restricted; i.e., they are XML Schema patterns, not XSLT patterns)
I've looked at the libxslt module pattern.c -- but I'm not quite sure
how to use it on its own... How do I create the required
xsltTransformContext when I don't have any transformations going on?

And... Which parts are actually public? (This may be a problem with my
installation, but I can find xsltMatchPattern() in the .h-file, but
not in the library itself, so I get linker problems if I try to use
it.)

Any help would, of course, be greatly appreciated.

Thanks,

- Magnus
