it seems like the majority of your posts deal with regex questions, and so I thought you might like to have some reference material to look at. things like the /i modifier will be old hat if you take the time to read these things over. without further ado:
from the docs:
perlre
perlrequick
perlretut
from perlmonks tutorials:
String matching and Regular Expressions which continues on through several different useful nodes
pattern matching exercises are the exercises to go along with that regex tutorial
common regex gotchas is chromatic's addition to the regex tutorial, and I always find his writing very very helpful
finally, from the literature you might try:
chapters 7, 8, and 9 of merlyn's Learning Perl (3rd Edition) (AKA "the llama")
chapter 5 of Programming Perl (3rd edition) (AKA "the camel")
Mastering Regular Expressions (2nd edition). I haven't looked at this one myself, but I understand it's excellent, and the second edition has just recently come out
<update>
that DamnDirtyApe suggested that I add japhy's book. I'd never seen it, but plan to spend some time with it tonight. Thanks DDA!

I often find that having a list of resources all in once place can be a big help, and your question just gave me an excuse to put one together on this topic. There's certainly far more out there in terms of resources, but even just reading the documentation provided with your distribution of perl or the tutorials offered on this site should help you to feel a lot more confident with your regexes.
hope you look into these,

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
