Rule to ignore a whole line of text [message #1780256]

I have the following grammar:

Model:
entities+=Entity*
;

Entity:

'.title=' Title=STRING ';'
entries+=Entry*
;

Entry:

(A | B |C| D)
;

A:
'.a=' name=STRING ';'
;

B:
'.b=' name=STRING ';'
;

C:
'.c=' name=STRING ';'
;

D:
'.d=' name=STRING ';'
;

What I want is to detect any lines that do not begin with those strings and ignore the entire line up until the line ending ';'.

Thanks very much.

You could try to define your own terminal rules that include the linebreaks.
You don't want to inherit from "Terminals".
You may want to use "hidden".
