PageQuery is an accurate, high performance URL query system
that allows you to automatically extract specific, or user
defined, 'nuggets' of data from a web page (a.k.a. screen
scraping). Any number of items can be configured into
a system for extraction, and once they are, the Page Query
Web Service will automatically detect their presence
on any page across an entire domain. These rules are created
using the PageQuery Builder application
and stored as Regular Expressions.
