=head1 DESCRIPTION

This module will remove an RSS item from its channel. Actually, it will remove any L<Mojo::DOM> element from its parent. Use L<App::Rssfilter::Filter::MarkTitle> for a non-destructive filter.

=head1 FUNCTIONS

=head2 filter

    App::Rssfilter::Filter::DeleteItem::filter( $item, $matcher );

Removes C<$item> from its parent and discards it.

C<$matcher> is an optional string specifying the condition which caused C<$item> to be removed, and is ignored; it exists solely so that L<App::Rssfilter::Rule/constrain> can set it to the name of the condition causing the match.
