I have an XML file, 
<doc>
<date name="processingtime">2011-04-09T11:12:22.049Z</date>
<str name="docuid">121422</str>
<str name="title">ABC</str>

<str name="docuid">13427</str>
<str name="title">CDE</str>

<date name="processingtime">2010-04-09T11:12:22.049Z</date>
<str name="docuid">89822</str>
<str name="title">LKK</str>

where a tag (<str name="docuid">) appears multiple times. i need to fetch data from all the docid tags and find max value from that. I used following code:: 
$html =~ s/<doc>/<doc>\n\n\n\n\n\n/g;
my (@lines) = split("\n\n\n\n\n", $html);
$cn = scalar(@lines);
for($i = 0; $i<$cn; $i++)
{

if ($lines[$i] =~ m/<str name="docuid">(.*?)<\/str>/)
{
    $docuid[$i] = $1;
}
}
my $max = max @docuid;

This code is solving my purpose, but is there any better way to achieve this.
