File Size:28537kb,
But for "real tests", send the original file you use direct
BTW How the hell did you develop this monstrous eregi?
For better maintenance, I�d cut it in several pieces,
or first make the inputfile smaller using grep " a href" > to test.file ,
This will reduce
fileaccess a lot, and takes microseconds to proceed.

Anyone care to test it on there machine? Full code (20 lines) with
