in reply to date of a web page

OP here. Basically, I wanted to download various webpages, and order them by their posted date. For example, following a news story that evolves over time, I'd like to order them by date. The Date::Parse module sounds promising so long as there is only one date in the written page. Any other ideas to try?

    Does the site provide rss-feeds? That might often give you more resonable data. How often do your script check these sites? If it checks reasonably often, you could maybe use your own time when the site lack something better?
      no, unfortunatly not all sites offer rss yet, and even then, a lot don't contain dates. I don't want to run this all the time. Basically, I'd like to do a search on a particular topic on the site, get the results back, take those links and turn them into a date ordered list.
