[antlr-interest] Generate a Pascal similar grammar

[wolfi9999 at gmx.de]

Hello!

I want to write a Pascal similar grammar which only
looks for if statements and function calls. All other
statements and texts are not interesting for me.
>From this I want to draw an activity diagram in an
UML Tool.

My question: is it possible to filter only for these
   two kind of statements (if, func call) and by which
   rule do I skip the rest of the text?

Thanks.

Regards
Wolfi
