You can access your desired information several ways using XPath. For example:
/Parameter/Value/Item
/Parameter/Value/Item[@Value]
//Item
These all can get you to the node you desire.
I assume from your Xpath that this is a snippet of the acutal XML file your are parsing. If you want just one of these values, you would want something like the XPath you mention in your post. But if you wanted all the Values in your XML, use the 3rd one I listed.
Check out W3 Schools XPath for more information on XPath.
One of the reasons I prefer XML::LibXML is the XPath support
Try
use XML::LibXML;
#Parse XML
my $template = 'xmldocument.xml';
my $parser = XML::LibXML->new();
my $doc = $parser->parse_file($template);
#Find desired node(s)
my @nodes= $doc->findnodes("//Item");
#Print results
for(@nodes)
{ if($_->hasAttribute("Value")
{ my $data = $_->getAttributes("Value");
print "$data\n";
}
}

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).
