class CSVParser(__builtin__.object)
`` | `Parser for CSV files. Parses CSV files including all subtleties such as: * commas in fields * double quotes in fields * embedded newlines in fields - Examples of programs that produce such beasts include MySQL and Excel For a higher-level, friendlier CSV class with many conveniences, see DataTable (which uses this class for its parsing). Example: records = [] parse = CSVParser().parse for line in lines: results = parse(line) if results is not None: records.append(results) CREDIT The algorithm was taken directly from the open source Python C-extension, csv: http://www.object-craft.com.au/projects/csv/ It would be nice to use the csv module when present, since it is substantially faster. Before that can be done, it needs to support allowComments and stripWhitespace, and pass the TestCSVParser.py test suite.`
| Methods defined here: __init__(self, allowComments=True, stripWhitespace=True, fieldSep=',', autoReset=True, doubleQuote=True) `Create a new CSV parser. allowComments: If true (the default), then comment lines using the Python comment marker are allowed. stripWhitespace: If true (the default), then left and right whitespace is stripped off from all fields. fieldSep: Defines the field separator string (a comma by default). autoReset: If true (the default), recover from errors automatically. doubleQuote: If true (the default), assume quotes in fields are escaped by appearing doubled.` endQuotedField(self, c) inField(self, c) inQuotedField(self, c) parse(self, line) `Parse a single line and return a list of string fields. Returns None if the CSV record contains embedded newlines and the record is not yet complete.` quoteInField(self, c) quoteInQuotedField(self, c) reset(self) `Reset the parser.
