Shaun,
You would want to use a switch (sometimes called "case") statement....try
something like this
MYSWITCH: for ($something) {
/string0/&& do {
&do_something;
last MYSWITCH;
};
/string1/&& do {
&do_something;
last MYSWITCH;
};
/string2/&& do {
&do_something;
last MYSWITCH;
};
#Default case
warn "None of the cases matched....doing something else";
&do_something_else;
}
I realize this is the long way to go about it, and it could be done in less
code, but I wanted to show you how to use a switch statement. In this case
I'd suggest just using the "|" in your regex.....like below
if( $something =~ /(string0|string1|string2)/) {
&do_something;
} else {
&do_something_else;
}
Hope this helps,
Kevin
