Detailed Description

template<typename ParserT>
struct lexer< ParserT >

Lexer class for CTTL XML stream parser sample.

ParserT

Template parameter specifying type of parser to be used with this lexer.

The lexer implements XML grammar for simple xml input test, published by the parser performance project: http://paper.sourceforge.net/:

  1:    grammar = node*;
  2:    node = pi | inode_element | text;
  3:    inode_element = openElement node* closeElement | closedElement;
  4:  
  5:    pi = "<?" name (CHARACTER - "?>")* "?>";
  6:  
  7:    openElement = "<" name attr* ">";
  8:    closeElement = "</" name ">";
  9:    closedElement = "<" name attr* "/>";
 10:  
 11:    text = (CHARACTER - '<')+;
 12:  
 13:    attr = name '=' value;
 14:    name = ALPHA (ALPHA | DIGIT | '_' | ':')*;
 15:    value = '"' (CHARACTER - '"')* '"';
 16:  
 17:    - Grammar terminals can be separated by any amount of whitespace.
 18:    - Grammar terminals are "text", "name", "value", and all literals.
