This can be simplified to

or (since this is Perl and TIMTOWTDI)

You are missing two lines here.

If you don't put those two lines you will be surprised by what Perl

Hi,
So I tried something like this .It works !
if( $_ =~ m/ID\s=\s"(.*?)"\sDirAbsolute/){
print " Test ID is $1 \n" ;
}else{
print " FAILED to locate Test ID \n" ;
}
May be its crude way.
Thanks

Hi Amichai,
first of all never write own code without these two lines:
use strict;
use warnings;
this should allways help a lot. Remember the e-mail from Chas Owens
regarding the "shuffling cards".

The problem was that the files I'm reading are generated on M$ servers in DOS

This meant that at the end of the file is a line containing the DOS EOF char
