Subject: Re: String.scan hangs in some cases?

Just for kicks, here was the original regex - attempting to match 
against a string containing an entire HTML page OR a style sheet.

/(?=<style)*?background.*?(?=-image)*?:.*?url\((.*?)\).*?(?=<\/style>)*?/

I was attempting to make the <style  and </style> parts optional.

As it turns out, there are so many different ways that a style can be 
specified in a HTML page, that I just went with the much simpler:

/background.*?:.*?url\((.*?)\)/i
