A computer-implemented method of retrieving information in a first markup language through a query engine and presenting the information in any required markup language. A user inputs a query and may invoke a number of transformative sequences. These sequences contain a markup language pattern and an action, which may include transforming the tags in the first markup language to tags in a different markup language. The appropriate transformative sequence is selected and the pattern from the transformative sequence is compiled. The compiled pattern is used to perform rapid and efficient searches of documents in the database. A predicate check using the binary coding of the node as well as ancestor information confirms the node. The leaf information associated with a confirmed node is then stored. If necessary, the action from the transformative sequence is applied to change the markup language of the leaf information to that of the user.
