twisted.words.xish.xpathparser : API documentation

XPath Parser.

Besides the parser code produced by Yapps, this module also defines the parse-time exception classes, a scanner class, a base class for parsers produced by Yapps, and a context class that keeps track of the parse stack. These have been copied from the Yapps runtime.

Class	SyntaxError	When we run into an unexpected token, this is the exception to use
Class	NoMoreTokens	Another exception object, for when we run out of tokens
Class	Scanner	Yapps scanner.
Class	Parser	Base class for Yapps-generated parsers.
Class	Context	Class to represent the parser's call stack.
Function	print_line_with_pointer	Print the line of 'text' that includes position 'p', along with a second line with a single caret (^) at position p
Function	print_error	Print error messages, the parser stack, and the input text -- for human-readable error messages.
Function	wrap_error_reporter	Undocumented
Class	XPathParserScanner	Undocumented
Class	XPathParser	Undocumented
Function	parse	Undocumented
