my goal: read a remote forum page get the post tiles, authors, views, replies.

so far ive got:

get the remote url, save it as a file, get the urls out of it.

the script above works, but it leaves me kind of wondering whats going on, i get a bunch of urls, but i dont get the text of what the url is for.

how can i get the whole html code between <a and </a> not just the [url]http://[/url] part ?
