1. A computer-implemented method for classifying source code, comprising: parsing the source code to identify individual classification elements, within the source code, representing separate code constructs; comparing an individual classification element representing an individual code construct with different schema elements within a markup language schema; applying a markup language tag to the individual code construct based upon the comparing; and generating a markup language formatted set of code constructs corresponding to the parsed individual classification elements, wherein the markup language formatted set of code constructions includes the individual code construct with the applied markup language tag; storing the markup language formatted set of code constructs in a source code archive; indexing the markup language formatted set of code constructs in the source code archive; keyword searching the indexed markup language formatted set of code constructs to locate markup language formatted code constructs; retrieving the located markup language formatted code constructs; and transforming the retrieved markup language formatted code constructs into source code suitable for code reuse.
