          }
        }
    );

        action    => 'MarkTitle[HELLO]',

    # <?xml version="1.0" encoding="UTF-8"?>
    # <rss>
    #   <channel>
    #     <item><title>it&#39;s hi time</title><description>hi</description></item>
    #     <item><title>HELLO - here we are again</title><description>hello</description></item>
    #   </channel>
    # </rss>

DESCRIPTION

This module will add some uppercase text to the title of a Mojo::DOM element. Use this module instead of App::Rssfilter::Filter::DeleteItem when you wish to verify that your matchers are working correctly, as MarkTitle will simply mark the title of matched items with a specific string, or the name of the matching module.

FUNCTIONS

filter

    App::Rssfilter::Filter::filter( $item, $matcher, $explicit_prefix )

Prefixes $item's title with $explicit_prefix (or, if not specified, $matcher) in uppercase. When called from "constrain" in App::Rssfilter::Rule, $matcher will be set to the nice name of the rule's condition, and $explicit_prefix will be the first bracketed argument.
