in reply to Re: Basic Regular expression
in thread Basic Regular expression

Start then capture 1 or more character upto "e" or "r"

If it was true, the OP would have received

$1="This is P"; $2="e"; $3="rl";
instead of
$1="This is Pe"; $2="r"; $3="l";

It actually matches until the end of the line as the OP expects, but its then forced to backtrack until it finds a position that's followed by e or r.
