Methods and systems for transforming a complex representation of computer code into a simplified representation of computer code are described. Parse nodes in a parse graph are traversed. Selected information contained within the parse nodes is hidden to create condensed parse nodes. The hiding prevents further processing of the selected information. Selected complex patterns in the parse graph are simplified to create simplified parse graph patterns. Branches on an AND/OR command tree are created from the parse nodes, the condensed parse nodes, and the simplified parse graph patterns.
