Sigh - use strict; use warnings;, post a complete sample that demonstrates the problem. As usual, here's a starting point:
use strict;
use warnings;
while (my $line = <DATA>) {
...
}
__DATA__
...
Dodgy stuff in your first post:
$line=; # Just plain wrong!
while ($line=~m/([123]?[.s]*[a-z\=.]+)/oi) # Where does $line get a va
+lue?
$t_book=~s/\l=([a-z]+)\/$1/ig; # The \/ is wrong!
$t_book=~s/<(|/)(B|I|SC|U)>//ig; # The |/ is wrong (and why would you
+want to capture it?)

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.
