Recently I discussed the way how xslt is implemented in php with some java user. We came to the conclusion that there is probably much overhead in php, since the xslt processor doesn't accept dom object.

When I'm building my xml dynamicly using a dom object, is has to be serialized to a string before it can be passed to sabletron. That means that sabletron has to parse that string again to make a dom object out of it.

To me that looks quitte inefficient. Why not let the xslt processor accept a dom object? That would probably speed up everything very much.
