It's not clear to me what you are trying to achieve here (assigning a hash ref to an array doesn't make sense), but the following may help:
use warnings;
use strict;
use XML::Twig;
use Data::Dump::Streamer;
my $xml = <<XML;
<config>
<computer id="one" type="mac" os="XP" >
<lease true="yes" />
<extra_device value="scanner"/>
<entertainment>
<game id="tekken" company="nameco" />
<platform value="pc only" />
<year value="1980" />
<game id="tekken 2" company="ninja" />
<platform value="pc and mac" />
<year value="1989" />
</entertainment>
</computer>
<computer id="two" type="pc" os="NT" >
<lease true="no" />
<work>
<software value="final" />
</work>
</computer>
<company_name id="nameco" origin="ca" type="violence" production="ye
+s">
<sponsor name="sony" percentage="30" active="true"/>
<sponsorlist>
<sponsor id="sony1" active="false"/>
<sponsor id="sony2" active="true"/>
<sponsor id="sony3" active="false"/>
</sponsorlist>
</company_name>
<company_name id="ninja" origin="ny" type="extreme violence" product
+ion="yes">
<sponsor name="WB" percentage="20" active="true"/>
<sponsorlist>
<sponsor id="WB1" active="false"/>
</sponsorlist>
</company_name>
</config>
XML
my $yahoo = 'one';
my @ones;
my $twig = XML::Twig->new (
pretty_print => 'indented',
twig_roots => {
computer => sub {oneHandler (\@ones, $yahoo, @_);}
}
);
$twig->parse ($xml);
Dump (\@ones);
sub oneHandler {
my ($ones, $yabal, $twig, $elt) = @_;
return unless $elt->att ('id') eq $yabal;
for my $child ($elt->children ()) {
my %atts = %{$child->atts ()};
next unless %atts;
push @$ones, \%atts;
}
}
Prints:
$ARRAY1 = [
{ true => 'yes' },
{ value => 'scanner' }
];
Perl reduces RSI - it saves typing

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.
