Dear deities,
I am writing an RSS aggregator and have chosen the XML::RSS parser to read the feeds. I have it all working except when there is an error in the feeds XML file. The documentation for XML::RSS states that a die is produced when there is an error in the parsed XML but I would like to trap this error and not die. I would then do a next to continue onto the next feed, maybe generating my own error message etc.
I am not sure how to wrap the XML::RSS in some form of error checking...
Example pseudo code:
!/usr/bin/perl -T $| = 1; use strict; use warnings; use XML::RSS; use LWP::Simple; use POSIX qw(strftime); my $there_is_a_feed_to_be_read = "true"; my $url_to_read = "http://xxx.xml"; my $url2parse; my $rss; while ( $there_is_a_feed_to_be_read ) { $rss = new XML::RSS; $url2parse = get( $url_to_read ); die "Could not retrieve $url_to_read" unless $url2parse; # all works up to this point but if there is an error in the # XML being read the next command chokes. # What I am looking for is some sort of wrapper to do a next # if there is a problem so we just step over the faulty feed $rss->parse($url2parse); # deal with the returned XML information here # . # . # . }
Not wanting to name names but at the present time the following feed has a raw & symbol in the text that the parser is tripping over.

Many thanks in advance
