DESCRIPTION

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

FUNCTIONS

filter

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

Removes $item from its parent and discards it.

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