in reply to newline behavior in Regular Expression

Congrats. I didn't even know that IE would honor <font size="+10"> but you proved it. I should print this question out as a poster for my bare wall here.

The $ means end-of-line, not end-of-string. The end of line is true just before any trailing newline character. So if $X had a newline before, it won't replace the newline after. One preventative measure would be to use chomp($X) beforehand.

    Nope. That's only the case with the option /m enabled. Unless I misunderstand what you mean...? Which is not exactly very clear to me.

    I think the OP's problem is that he used /PAT(.*?)$/ and expected to match the final newline as well. As the /$/ does match just before the final newline as well as at the very end of the string, the non-greediness makes it pick the shortest match, thereby leaving the newline alone. Drop the '?' to make it work.
