XML::RSS::Headline - Persistant XML RSS Encapsulation
Headline object to encapsulate the headline/URL combination of a RSS feed. It
provides a unique id either by way of the URL or by doing an MD5 checksum on
the headline (when URL uniqueness fails).
A XML::RSS::Headline object can be initialized either with headline/url or with
a parse XML::RSS item structure. The argument 'headline_as_id' is optional and
takes a boolean as its value.
The id is our unique identifier for a headline/url combination. Its how we can
keep track of which headlines we have seen before and which ones are new. The
id is either the guid from rss, the URL or a MD5 checksum generated from the
headline text (if $headline->headline_as_id
The unique id used by RSS, set if its available. The 'id' method return guid or
url if guid is not available.
This method returns the headline as either an array or array reference based on
context. It splits headline on newline characters into the array.
Init the object for a parsed RSS item returned by XML::RSS.
Set the time of when the headline was first seen. If you pass in a value it will
be used otherwise calls Time::HiRes::time()
The time (in epoch seconds) of when the headline was first seen.
The time (in epoch seconds and milliseconds) of when the headline was first
The rss headline/title. HTML::Entities::decode_entities is used when the
headline is set. (not sure why XML::RSS doesn't do this)
The rss link/url. URI->canonical is called to attempt to normalize the URL
The description of the RSS headline.
A bool value that determines whether the URL will be the unique identifier or
the if an MD5 checksum of the RSS title will be used instead. (when the URL
doesn't provide absolute uniqueness or changes within the RSS feed)
This is used in extreme cases when URLs aren't always unique to new healines
(Use Perl Journals) and when URLs change within a RSS feed

A high resolution timestamp that is set using Time::HiRes::time()
the object is created.

thanks for actually taking time to use the code and give good, honest
Thanks to Aaron Krowne for patch to use guid as the unique id instead of url if
