Hi Monks, this might be a dumb question, but I'm still learning.

I'm doing a series of string substitutions in a file. I have a hash, something like this:

my %subs = (
"Xaa1" => "sub1",
"Xaa11" => "sub2",
);

foreach my $s (keys %subs){
 $data =~ s/$s/$subs{$s}/g;
}

I'm sure you can see the problem here. If the string is "Xaa11" it might first substitute "Xaa1" and never see the final "1", so the result ends up being "sub11" instead of "sub2".

Am I going about this the right way, and how to I make sure it checks to the end of "Xaa11"?

Thank you!
