Can you automate web data base (html) searches?

I am trying to figure out how to use automator to seach a particular web page each day and extract or hi-lite specific text or terms. Is there a way to do this or at least have automator extract all of the html text from a page and turn it into a text document?

Thank you,

David-

What page do you want to check and what text do you want to extract? No way to guess at this one.

Thank you for the reply. I want automator to search the following web pages: http://www.wakegov.com/tax/realestate/foreclosures.htm and http://classads.triangle.com/index.php?a=5&b=2&page=2&c=&sort_by=none&dir=desc&num_results=20 every day for specific key words. Example: “bennet” or phrases “bennet ave”
Do you have any idea how I can automate my mac to do this?
