Pulling in an RSS feed for parsing

bradcathey has asked for the wisdom of the Perl Monks concerning the following question:

Fellow Monasterians,

Doing my first XML coding and am running into a speed bump. The following returns a error:

use strict;
use Data::Dumper;
use XML::Simple;

my $xml = new XML::Simple (KeyAttr=>[]);

my $xmlresource = "http://prlmnks.org/rss/458722.xml";

my $feed = $xml->XMLin($xmlresource); #line 20

print "Content-type: text/html\n\n";
print Dumper($feed);

ERROR:
File does not exist: http://prlmnks.org/rss/458722.xml at /usr/www/use
+rs/highgate/admin/cgi-bin/xmltest.pl line 20
[download]

If I upload a ____.xml file to the cgi-bin directory, it finds the file without incident. The XML::Simple docs mention *file* but not URL. So, how, or with what module, would I use to pull in an xml file for parsing? Thanks!

—Brad

The LWP library can fetch pages. LWP::Simple provides a very simple interface, HTTP::Request::Common for middle ground, or HTTP::Request for the most flexible interface. The latter two require the use of LWP::UserAgent. LWP is not part of core Perl, but it does come with ActivePerl (for Windows).	[reply]

You can use LWP::Simple to grab the file and send the contents to XMLin(), which can accept a string. `my $xmlresource = "http://prlmnks.org/rss/458722.xml"; use LWP::Simple; my $xmlstring = get $xmlresource; my $feed = $xml->XMLin($xmlstring);` [download]	[reply] [d/l]

Both replies were right on. I tried LWP::Simple and it worked like a charm. I did have to drop the OO `$xml->`. Anyway, big day for this monk. —Brad "The important work of moving the world forward does not wait to be done by perfect men." George Eliot	[reply] [d/l]

Also, see URI::Fetch. It does a few things for you - last-modified headers and ungzipping, and such. Nothing you can't code yourself, but that's what CPAN is for, right? :)	[reply]

To parse RSS-files, I would recommend to use XML::RSS...	[reply]

Last time I checked XML::RSS leaked memory like there's no tomorrow, so I ended up writing my own parser based on XML::LibXML. XML::RSS surely useful, but you have to be careful with it, especially when you use it in a long-running process.	[reply]

Ever plan on releasing your module into CPAN? -Bryan	[reply]
