Another strategy:
use XML::LibXML;
my $d = XML::LibXML->new->parse_string(join "", <DATA>);
for my $dead ($d->findnodes(q{/opt/node[val = "2"]})) {
$dead->unbindNode;
}
print $d->toString;
__END__
<opt>
<node>
<val>1</val>
</node>
<node>
<val>2</val>
</node>
<node>
<val>3</val>
</node>
</opt>
which results in:
<?xml version="1.0"?>
<opt>
<node>
<val>1</val>
</node>
<node>
<val>3</val>
</node>
</opt>

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.
