But for "real tests", send the original file you use direct
BTW How the hell did you develop this monstrous eregi?
For better maintenance, IŽd 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
