How to parse google's response?

I do开发者_开发百科n't know if I said it right. I am thinking of making a tool that extracts data from google searches. Say I want to get the number of pages returned for a particular query and feed that to my program/tool. How do I go about this?

From the Google Terms of Service:

"You specifically agree not to access (or attempt to access) any of the Services through any automated means (including use of scripts or web crawlers)..."
