1. A method for performing operations on structured text stored in a computing system, the method comprising: converting structured text in a computing system into strings of tokens representing text formats; identifying repeating patterns of said text formats within said structured computer text; determining pattern transformation procedures for transforming text strings within said structured computer text; building transformation algorithms for performing said pattern transformation procedures on said text strings; applying said algorithms to said text strings within said structured computer text that match a pattern; whereby said structured computer text is transformed from a first pattern to a second pattern.
