Abstract
A system for automated acquisition of content from an application includes a static analysis module. Using static analysis (analyzing code of the application independent of executing the code), the static analysis module identifies application state templates of the application and identifies user interface elements that, when actuated by a user, transition between states instantiated from different ones of the identified state templates. A graph creation module creates a graph data structure including nodes corresponding to the identified state templates and edges connecting the nodes. The edges are transitions corresponding to the identified user interface elements. A link extractor module executes the application and determines and records paths to states within the executing application according to the graph data structure. A scraper module, within an executing instance of the application, extracts text and metadata from states corresponding to endpoints of the recorded paths.
