Re: Matching problems

The regexp you're using will get a false hit on thistle.

Try

my $search = "this";
my $data = "This is the test text for THIS routine.";
my $bs = "<b>";
my $be = "</b>";
my $count = $data =~ s/\b($search)\b/$bs\1$be/gi;

The backreference (\1) preserves case.

Update: Kanji is right. Use $1 instead of \1.

`$1` also preserves case, with the added benefit of being `-w` / `use warnings;`-friendly! `my $count = $data =~ s/\b($search)\b/$bs$1$be/gi;` --k.	[reply] [d/l]

This is working quite well, I appreciate the help. An to the rest of the monks that responded thanks also. Using ALL of your reply's I was able to get a little better grasp on how regexp works. I still have some reading and studying to do, but I have accelerated my learning a bit by reading all the helpful information here. Thanks!	[reply]
