Hi i have previously managed to extract links from html using the
follownig code:
html.scan(/src\s*=\s*\"(.*?)\"/im) { |item|
link = item.to_s
}
this worked great, however i want to extract some other text from html,
and i dont quite understand how the paramaters passed to the scan method
work.
can anyone explain or have a good link about this?

The ruby api [1] has some useful information on the scan function. The page you are interested in is probably [2]. If you are going to be manipulating html documents, you might want to check out Hpricot [3], or some other html parser.
