Lexed

A trivial lexer for Javascript.

var rules = {
	'<\/[^>]+>': Lexed.IGNORE, // ignore close tags
	'<[^>]+>': Lexed.IGNORE, // ignore open tags
	'[^<>]+': function(text) { return text; } // return matched text content
};
var l = new Lexed('<div class="intro"><b>Hello!</b></div>', rules);

var token;
while ((token = l.lex()) != Lexed.EOF) {
	console.log(token); // writes Hello!
}

It also supports state transitions.

Take a look at the tests and examples folders for more usage examples.
