Re: XML::Simple Array bombs out with 1 Item in document

in reply to XML::Simple Array bombs out with 1 Item in document

Hmm ... well ... once you get paste the dodgy use of eval (do you really need to do that ... probably not). Basically the core problem is your data structure is not a hash of hashes but a hash of arrays of hashes.

  foreach my $e ( @{$data->{channel}[0]{items}} ) {
   ...
   print $e->{title}[0] ...
  }

but you're probably better of just using XML::RSS:

my $rss = XML::RSS->new( version => '2.0' );
my $rss->parse( $rss_xml );

# print the title and link of each RSS item
foreach my $item ( @{$rss->{items}} ) {
  print "title: $item->{title}\n";
  print "link: $item->{link}\n";
  print "desc: $item->{description}\n";
}

Thanks. But my code does work well when there are 2 or more items	[reply]

That's great. But I hear the code doesn't work well when there is only 1 item. And that's the case that derby is talking about. You could check to see if you've got a hash (1 item) or an array (2+ items), using ref, or see about making them always be arrays in the module's options (see ForceArray).	[reply]
