php 5 & XSLT: How to register own handlers for SAX, Error and PI ?

Hello

I am looking for a possiblity to register own handlers for my XSLT
processor. In PHP4 exists some hacks but not any more for php 5. So
does somebody know a possiblity?

e.g my expectation

$xslProc = new XsltProcessor();
$xslProc->registerSaxHandler($saxHandler);


// another way would be to set/get the internal XML parser from the
XSLT processor and set it than manually? but there exist no
documentation how I can set the xml parser for the xslt processor.
http://ch2.php.net/manual/en/functio...on-handler.php

i.e. old php4 hacks, which could not any more be used
http://ch2.php.net/manual/de/functio...ax-handler.php


any ideas?

Many thanks

regards
Mark
