First off, try using <code> tags for your code.

Second, when dealing with XML, it's highly recommended to use an XML parser of some sort. My favourite is XML::Twig, but others exist. There probably is even a wrapper around the XML parsers that help parse RSS feeds. Once you've retrieved the data into your $scalar, you can put it into these parsers and be able to get the data you want much more easily.

#!/usr/bin/perl -w

use LWP::Simple;
use XML::Twig;
my $twig = XML::Twig->new();
$twig->parse(get 'http://www.frequencyyouth.blogspot.com/atom.xml');
my @entries = $twig->get_xpath('entry');
foreach my $entry (@entries)
{
  my @title = $entry->get_xpath('title');
  print "Found ", $_->text(), "\n" for @title;
  my @content = $entry->get_xpath('content');
  print " -> ", $_->text(), "\n" for @content;
}

I guess it's time for the "obscure XML::Twig method of the day" link: you can also use the parseurlmethod to get the data directly.

This would do the same thing your code does:

#!/usr/bin/perl -w
use strict;

use XML::Twig; # to get the entries
use YAML;      # to dump the data

# $entries is a reference to an array of entries 
# each entry contains { title => <title_text>, content => <content_tex
+t> }
my $entries=[]; 

my $twig = XML::Twig->new( twig_handlers => { entry => sub { store_ent
+ry( $entries, @_); } } )
                    ->parseurl( "http://www.frequencyyouth.blogspot.co
+m/atom.xml");
print Dump( $entries);
exit;

sub store_entry
  { my( $entries, $twig, $entry)= @_;
    push @$entries, { title => $entry->field( 'title'), content => $en
+try->first_child( 'content')->xml_string };
  }
