Re: [xslt] suppressing warning from document()

["Marc Adkins" <madkins whitepages com>]

You might investigate XML::LibXML::InputCallback:

	
http://search.cpan.org/~pajas/XML-LibXML-1.63/lib/XML/LibXML/InputCallba
ck.pod

If you override that you can search for the file in your own code.  This
may not work with AxKit (which I haven't used) and it may have some
performance issues.  I implemented it once and got it working but ended
up deciding to pre-process the XSLT instead which worked better for my
purposes.

It would be nice if there was a "include path" for XSLT.  Though I
suppose that would be engine-specific, not part of the specification,
and therefore not always supported.  Or maybe it's there and I'm too
ignorant to know.  ;)
