This is the problem, if I reduce the code, it works. I've checked the
XHTML code and the Regular Expression, but everything is fine.

Please provide a very short example without endless pieces of HTML/XML
code.

Description:
------------
I'm trying to use preg_replace to evaluate my own XHTML tags, sending
their arguments and contents to another funcion. There are two uses,
the simple, without content (like <wstag x="y" />), and the complex,
with content (like <wstag x="y">x</wstag>). Each one is parsed by their
own function, and to evaluate ALL the complex tags (even the tags inside
other tags) I'm using a while condition.

The problem is very odd, it happens when I use more than one complex
tag, and some simple tag before the complex ones, all of this inside
another complex tag (you will understand better reading the code), with
few complex lines or without simple tags before them, the results are
good, but otherwise, the while condition just doesn't work and the
Apache thread takes much more time proccessing the script (I don't know
why, as the while code just repeats two times).

Look at the URL below for more details and note the first code should
work (try removing the second one), but not the second!
