Text.XML.HaXml.Xtract.Lex
Description
This is another hand-written lexer, this time for the Xtract command-language. The entry point is lexXtract. You don't normally need to use this module directly - the lexer is called automatically by the parser. (We only expose this interface for debugging purposes.) The Xtract command language is very like the XPath specification.
