Hi,
I have to parse a textfile which is divided in several
groups. Inside of this groups where several options.
This option can occur in any order, but only zero or
one times. I have this construction:
header: BEG 'HEADER'
( project_no version
| version project_no
| version
| project_no
|
)
END 'HEADER'
;
This is OK for only two options, but i have also
sections with mor than ten options.
How can i made this rule easier? Does i have to track
this by hand?
Martin
