in thread Problems with regex grouping

To avoid throwing stuff in $1 when you don't need to, there is a great feature called clustering in REs with the (?:stuff here) stuff :). Just change
/<a href="(mailto:)?([^"]*)">([^<"]*)<\/a>/g

/<a href="(?:mailto:)?([^"]*)">([^<"]*)<\/a>/g

And that way nothing will be put in $1.

You may also want to consider chomping  $2 and $3 because a newline could get in there somewhere and cause some trouble.

Hope I helped out. :):):) Later

$_.=($=+(6<<1));print(chr(my$a=$_));$^H=$_+$_;$_=$^H; print chr($_-39); # Easy but its ok.

[shmem]: the biker stopped the machine at the table and took off his helmet.
