Thanks guys, for all the help.  
The reason that I was thinking 'grammar parser'  was that the spec of this
format may change.  I was looking for something that would be quick, but
easily extended as the grammar changed/evolved.  Also my next project will
need the same functionality if not an extension of the same grammar.
	Again thanks,
