Description:
------------
I must say in honesty that I have only verified in 5.3.6 and 5.2.17, I have no 
option to verify in the very latest versions.

I have created a script that parses large XML files. Essentially these files are 
single line documents without returns between the tags. When running the script 
(see URL), I get a timeout after processing just a few nodes.

Incidentally I had a copy of the same XML file at hand that had been formatted for 
readability in BBEdit. To my surprise this version was parsed to the very end! 


Test script:

Two version of the same XML file

Expected result:
----------------
Timeout

Expected result should be a completely parsed XML file of course...

Looks fine here, the script spends lots of time in preg_replace.
