Not entirely sure I understand, but maybe you want a character class [...], i.e.
for ("< foo\n", "> bar\n") {
my $lines = $_;
if($lines =~ m/[<>]/){
$lines =~ s/^[<>]\s//;
# do something else...
}
print $lines;
}
__END__
foo
bar
Update: as grizzley suggested, you could also use /<|>/ (alternation). While that would even be one char less to type in your match, it would become slightly more unwieldy in case the regex needs to contain other stuff, like in the substitution:
$lines =~ s/^(?:<|>)\s//;
(the (?:...) groups without capturing)

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).
