Difficult problem... anyone?

[Anon]

I realise this is a difficult if not unworkable problem, but if it's possible to resolve I think this is the place to find out:

Basically I want a script to search a file for any lines with links featuring a certain word; let's say I have a .htm file with a list of links and I want to find all the links on that page which feature the word "profile". Then, have them output to the page with this script on, as a list.

If I've made this sound confusing the jist of my question is this: How do you strip a file containing lines of links to just the ones you want and then output them on a page?

Hope that's ok! Thanks in advance, Andy :o)

regular expressions are your friend, have a read up on 'em. it is possible, but I won't do it for you because you'll have fun learning regexps chuckles
