System and method for extracting content elements from multiple Internet sources

摘要

A system for automatically extracting data from at least one electronic document accessible through the Internet or other computer network. The system records a sequence of actions operable to electronically navigate to a target page of the electronic document, the target page including a plurality of elements each having contents and a structural definition wherein the structural definitions interrelate the plurality of elements to specify a target pattern for a select subset of the plurality of elements. After recording the navigation path and the target pattern, the system automatically accesses the target page according to the recorded sequence. When the target page is accessed, the system automatically identifies, copies and processes selections from the plurality of elements dependent upon the target pattern.
