You can use an error action to do that.

Hi Adrian,
Thanks. I'd missed the longest-match kleene star documentation.
Sorry if this is a stupid question -- I'm looking for the best of both worlds.
How do I get a longest-match kleene star machine to start over if there is an
error?
For example, a document of "mailto:ema...@x ... mailto:ema...@y ...
mailto:invalid_email ... mailto:ema...@z"; will find the first two but will exit on
the third invalid_email when I really want it to keep going and find ema...@z.
Thanks,
Eric

Use:
mail := (any | mailto)**;
For the answer why, please see chapter four of the manual.

If I have two ORed machines, is there a leaving action I can get when a machine
is finally exiting?
For example, I believe this is a simplified form of my parser:
host = [A-Za-z0-9\-.]+;
mailto = (/mailto:/i sender_chars+ '@' (host %mailto_end)) $mailto;
mail := (any | mailto)*;
The %mailto_end will get executed on every single character of host. I just
want it to pick up the last character of host. Is there a way?
Cheers,
Eric
