I run into another issue with my grammar: My input record contains a common part and an extended part. Based on the value of the common part, the extended part will be different. So, I am thinking of parsing the common part first and check the common's value and then parse again for the rest of the record. How do I tell pyparsing to start the 2nd parse at the exact location where the 1st parse left off?
###################################### from pyparsing import * common = Word('aA').setResultsName('value') extend1 = Word('b') extend2 = Word('c') result = common.parseString(record) if result.value == 'a': result1 = extend1.parseString(???) else: result2 = extend2.parseString(???) ###################################### Thanks, Khoa -- http://mail.python.org/mailman/listinfo/python-list
