Go up one level in this thread
Steven Edwards put out a toolkit for dealing with chess notation -
e.g. Crafty uses it for parsing EPD. It looks to me like it has
some support for PGN input-output also. The code is big and not
very scrutable but may beat writing your own.
Note that parsing straight PGN (Even ill-formed examples) is not
terribly hard but handling PGN with subvariations and
annotations is a little harder. Not clear if you want to do go this
far unless you are writing a sophisticated chess viewer. 90% or more
of the PGN out there is unannotated.
