Wildcard matching

[jwcarlton]

I'm trying to find and replace any non-alphanumeric character (or lack
thereof), followed by a specified word, followed by any other non-
alphanumeric character (or lack thereof).

Here's where I am so far, using "jason" as the specified word:

$comment =~ s/(\W)jason(\W)/$1*****$2/i;

Specifically, I want to catch things like " Jason" (notice the opening
whitespace), "<br>Jason!", "***Jason***", and "<br>Jason\n". I'm not
so concerned about underscores, which I understand aren't included in
\W.

Any suggestions?

Hello,
well i don't know if i understand well what you want to do... but i'll
give a try
if you want that
" Jason" => " *****"
"<br>Jason!" => "<br>*****!"
"***Jason***" => "***********"
"<br>Jason\n" => "<br>*****\n"
then your RE is correct, you just have to add a * quantifier after \W
(since "lack thereof" is OK), don't you ?

Cheers,
azra

Wouldn't it be easier to just match word boundaries (you know, with \b )?

$comment =~ s/\bjason\b/*****/gi;
