A rule creation application uses a reference web page, and user input regarding information displayed thereon, to generate a rule for extracting such information from the web page. The rule uses a structured graph representation of the web page, such as the page's Document Object Model (DOM), to extract the information. In addition to being applicable to the reference web page, the rule may be used to extract information from other web pages that have a similar structure.
