I'm tasked with implementing a non-trivial XSLT transform (needs to read multiple docs and produce multiple HTML result files) within a PHP-based system.

I have zero experience with PHP so kind of shooting in the dark here.

I know that PHP uses libxml natively and so only provides XSLT 1 support out of the box.

I see also that it's possible to integrate Saxon using the PHP Java bridge. However this client appears to want to avoid the use of Java in this system (although I need to confirm that).

My question: Are there any XSLT 2 (or greater) options for PHP that do not require Java?
