You're not going to find a pre-written script to do what you want. What you want to do is highly dependent on the web page and what parts you consider "useful information".

You'll almost certainly need to use a regular expression to extract the data. See here:

Regular expressions are hard to learn, but very powerful once you are used to them.

You could also use the regular string searching/chopping functions, though it'll be more work, possibly a lot more:
