Retrieve specific xml content from given url

[conandor]

I want to get a specific string, eg. 123 in <received>123</received> from an XML that will retrieve from url. I have write a code but stuck with an error msg:

Attempt to bless into a reference at /usr/share/perl5/XML/Twig.pm line
+ 392.

any idea to solve it? The code

use XML::Twig;
use LWP::Simple;

my $url = 'http://mywebserver/status.xml';
my $twig = new XML::Twig(TwigRoots => {
    'smsc/received' => sub {$author = $_[1]->text;  }});
$twig->nparse( $url );
$twig->print;

Please include a bit more information/markup.

• please check the node of your question and update the formatting (<code>, ...)
• 192.168.x.x is private, so a short version of status.xml might be interesting.

Thanx
Peter

Update: thanx for fixing the formatting:). WRT my 'private IP range' in the URL you initially provided: can we have an example of the input as well (mywebserver's still not on the internet)?

nparse is a constructor, use xparse

Here is example

#!/usr/bin/perl --

use strict;
use warnings;

use XML::Twig;
use LWP::Simple qw( $ua );
$ua->agent('Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)');

my $url  = 'http://search.cpan.org/uploads.rdf';
my $twig = XML::Twig->nparse_pp(
    TwigRoots => {
        'item/title' => sub{},
    },
    $url
);
$twig->print;

__END__

and example output
