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. Previous Comments: ------------------------------------------------------------------------ [2004-08-24 08:38:50] [EMAIL PROTECTED] Please provide a very short example without endless pieces of HTML/XML code. ------------------------------------------------------------------------ [2004-08-23 20:34:42] wesleygoku at yahoo dot com dot br 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!
