Martel is a parser generator, written in Python, which takes a regular expression grammer for a format and turns the resultant parsed tree into a set of callback events emulating the XML/SAX API. It was originally intended for use in biocomputing applications (such as Biopython - http://www.biopython.org/), where there is often a need to parse existing flat and semi-structured file formats. However, it is generally applicable to the parsing of such files in all fields of endeavour.
