Hi all.

I'm currently in the process of teaching myself how to use XPath and Perl to parse XML documents (most notably, the chatterbox feed). After reading the documentation, I felt compelled to inquire about removing the attribute name in the output (please see below):

<?xml version="1.0" encoding="ISO-8859-1"?>
<CHATTER>
<INFO site="http://perlmonks.org/" sitename="PerlMonks" ticker_id="158
+34" gentimeGMT="2007-01-05 
23:29:59" xmlstyle="old" xmlmaker="XML::Fling 1.001" count="3" lastid=
+"419432">
Rendered by the Chatterbox XML Ticker</INFO>
<message user_id="22609" author="tye" time="20070105182057">
is "this proxy" that you mentioned relatively new?</message>
<message user_id="170442" author="jdporter" time="20070105182124">
is that a problem?</message>
<message user_id="170442" author="jdporter" time="20070105182217">
oh, sorry. yes, looks like [merlyn|he] is having a problem.</message>
</CHATTER>

By using the short program provided by the module's author and what I had already gleaned from various online tutorials, I was able to display the value of each 'author' attribute:

#!/usr/bin/perl
use warnings;
use strict;

use XML::XPath;
use XML::XPath::XMLParser;
    
    my $xp = XML::XPath->new(filename => 'pm.xml');
    
    my $nodeset = $xp->find('//@author'); # find all authors
    
    foreach my $node ($nodeset->get_nodelist) {
        print XML::XPath::XMLParser::as_string($node), "\n\n"; }
[download]

Output:

C:\Perl\bin>perl test.pl
 author="tye"

 author="jdporter"

 author="jdporter"


C:\Perl\bin>
[download]

Is there a method I'm unaware of that will display only the value(s) and omit the atttribute 'name='(?)

Thanks,
