Right now I'm developing a "news" kinda thing for a site I'm working on, and if it works well (a relative term), I may use it else where. I'm using XML to create "news listing" and post them on the front page of the site. Thank God for XML::Simple! It make the conversion process very...well, simple. My problem is in-between convertions.

First I parse my XML file into a ref (my $data = XMLin('./this.xml')). Data::Dumper would print something like this:

$VAR1 = {
          'news' => [
                      {
                        'title' => 'news1',
                        'content' => 'Article Contents...blah',
                        'date' => '08-03-01'
                      },
                      {
                        'title' => 'news2',
                        'content' => 'Article Contents...blah',
                        'date' => '07-20-01'
                      }
                    ]
        };

Then I want to be able to delete a user specified ($match) entry from the file (perl psuedo-code: DELETE ENTRY from $data->{news} WHERE ENTRY->{title} is $match). I'm confused on how to do this because 'news' is an anon array of hashrefs. I tried a few things, but my only real idea would be to shift each entry individually see if they match, then push them back if I don't want to delete them. There has got to be a better way.
