Re: [Pyparsing] Java grammar

[Mark L. <bre...@ya...>]

Thanks for the response Paul.

I thought that this would be the case having done a fair bit of research 
before posting, but nothing ventured...

The data at the link looks very useful, I'll have a play later on today. 
  I'll also keep in mind your advice on the low level tokens, might well 
save me some grief.

If I do manage to get anywhere I'll let you know, maybe another flag to 
fly for pyparsing.

Kindest regards.

Mark Lawrence.
