Abstract
A method and apparatus for filtering an input text stream includes receiving a definition of a filter configuration and modifying the input text stream according to the filter configuration so as to generate a filtered text stream. The filtered text stream includes positioning information for the input text stream. The positioning information may be useable by a downstream scanning device of a parser.
