stripping content and parsing returned pages?

I have been looking everywhere for any tips or tutorials on, posting to separate websites and parsing the return values for input into a mysql db. I understand the parsing or stripping of html content from a page, but not how to post to a form on a different site and once the values are returned parse and redirect. I have read alittle about using CURL to perform some of this, but no real help there. I need to post to a login script, then once the page is processed, I will parsed the returned page for the data after logined. any help please?
