Monks,
I have a short script that looks for commands and arguments
buried within an email message. Since email sometimes
inserts garbage (salutations, signatures, etc) before and after the message text, I need to find valid commands within
the text.
I know the list of valid commands, and in this case, valid
args are numeric. So, for the input "garbage validcommand 1234 221 garbage 999 213", I need to
parse out the args "1234 221", and throw the
rest out. The number of args can vary.
I've found something that works, but it seems inelegant:
$string="garbage validcommand 1234 221 garbage 999 213";
while ($string =~ s/validcommand\s+(\d+)/validcommand /) {
push(@args,$1);
}
Anyone have some better ideas ?
