PGN and PHP - Regex

rfurdzik

Trying to parse Chess PGN file. Please see sample at the end.

Suggested Regex:

(\d+).
([KQNBR])?
(([a-h][1-8])|((1-0)|(0-1)|(1/2-1/2)|(*)))([!?+]|ep)
(([KQNBR])?
(([a-h][1-8])|((1-0)|(0-1)|(1/2-1/2)|(*)))([!?+]|ep))?

I think there is one small problem with our Regex.What about comments and subvariations ? The move can start like this:

1)
1. Ng1f3 --> white

2)
1... Ng8f6 -> black after comment or subvariation.

3)
1. Ng1f3 Ng8f6 -> black after white's move

I guess in parsing (I'm not sure if this would be the correct term here) we need to output which side is on the move. I thought this may do it:

([1-9]+[0-9]?/.)|([1-9]+[0-9]?/...)
([KQNBR])?
(([a-h][1-8])|((1-0)|(0-1)|(1/2-1/2)|(*)))([!?+]|ep)

But this statement does not parse black's move in scenario 3)

Please notice that by checking the first element of the output array (for each match of course): $matches[0][0] we would know if it was white's or black's move.

This statement does not parse subvariations (those can be nested) and comments. I thought maybe those can be done using recursive option -R

Please see http://www.php.net/manual/en/ref.pcre.php for Regular Expressions in PHP - Perl Compatible.

Maybe it is easier to do char by char as suggested earlier ?
