Hi,

Can some one explain what I am doing wrong?

My lookahead is set to 5

and I want to find the "a href" statment

I tried the following grammar

QUOTE_HREF
	:	'<''a' 'h''r''e''f'  	
	;

and also

QUOTE_HREF
	:	"<a href"
	;

But my generated code only stated the following

				else if ((LA(1)=='<') && (LA(2)
=='a')) {
					mQUOTE_HREF(true);
					theRetToken=_returnToken;
				}

How can I get it to to do more than 2 lookahead as it is now picking 
up statement in my code that have < (greater than sign) and some text.

Regards

Colette
