Hi,
we miss the scheme facility from PHP4's XSLT extension. So, we are
making a new one for PHP5's XSL extension, i.e. interfacing libXSLT's
xsltRegisterExtModuleFunction. If nobody else have done it/is doing it
we'd like to contribute.

Can't you just use the stream-wrappers provided by PHP5? These are very
well supported even in xslt. What's the difference between them and the
sablotron way? Besides the different API in PHP userland?

Don't know the stream-wrappers, but from what I can see it doesn't do
what we need. We want to be called by XSLT (with args etc) when XSLT
meets registered elements&NS. So if you want a stylesheet with side
effects, say that search in a database, just chaning the stream of XML
doesn't help. XSLT must be in control - must have processed the args to
the handler A stream approach is "separate" pass. Again, I may have
misunderstood something, so we'd really like to know if it can be
achived already..

Just as an update to this question
According to Adam, the stream-wrapper support in ext/xsl seems to have
the same possibilities as the schemes support in the former sablotron
extension. But he will further look into it and keep us/me updated about
the outcome ;)
I will talk about stream-wrapper support in ext/dom and ext/xsl in my
talk next week at the php conference (and in the slides/examples
published afterwards) ;)

I've wrapped made a stream class with methods stream_open, stream_read,
stream_tell, stream_eof, stream_seek, stream_stat, stream_close. When I
use this handler from within XSLT I get :
*Warning*: xsltprocessor::importStylesheet() [function.importStylesheet
]:
tkl_file_stream::url_stat is not implemented! in
*/home/adam/proj/httpd/htdocs/tkl5/xsl-ex2.php* on line *70*
What's url_stat supposed to do? Prototype?

Looking at the PHP source, I decided to use:
function url_stat ($path)
{
return array();
}
with satisfactory results, so far.

Yep, it's supposed to have the same format as the array returned by
`fstat()`. But an empty array is ok ;)
