One thing you can add to his code if you only have one occurence of @user_info in the whole file is an exit from the loop as soon as you have found your data
That's a very good point! Here's two more variants, the first if the start and end tag should be captured, the second if they shouldn't (replaces the if/elsif):
if ( my $flag = /\@user_info_start/ ... /\@user_info_end/ ) {
push @userinfo, $_;
last LINE if $flag=~/E0/;
}
# - or -
if ( my $flag = /\@user_info_start/ ... /\@user_info_end/ ) {
last LINE if $flag=~/E0/;
push @userinfo, $_ unless $flag==1;
}

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).
