I could use a little help here. Alright, let's say I have this here HTML file, and I want to extract some of the things in brackets (which are just placeholders - in the HTML files I'm actually extracting data from there will be actual content where the brackets are) using grep, then send that data to a file. I'm not entirely sure which regular expressions to use. Also, for a given piece of data I don't want the regular expression to return more than one match. Oh, ignore all the broken links and images in the linked-to HTML file - they're supposed to be broken.
