Another way ... :-)
#!/usr/bin/perl -w
use strict;
use warnings;
my $filename = 'library.xml';
use XML::LibXML;
my $parser = XML::LibXML->new();
my $doc = $parser->parse_file($filename);
print "\nBooks\n";
my @nodes = $doc->findnodes("/library/book[last()]");
foreach my $node (@nodes) {
print $node->findvalue( 'title')."\n";
my @authors = $node->findnodes('author');
print "Authors:".scalar(@authors)."\n";
foreach my $auth (@authors) {
print $auth->textContent()."\n";
}
}
If any of my proposed solutions have minor errors, it's because I don't waste my genius on trivial matters. :-P

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
