[antlr-interest] Simple parsing question

[George J. Shannon]

Attached is a snippet of the grammar in question, where tagCommentNbr is the
integer value enclosed in brackets that I referred to in my email post.
George

tagCommentElement returns [ParserTagCommentElement pTagCommentElement]
@init 	{
	pTagCommentElement = new ParserTagCommentElement(); //db not req'd
	}
	:
	tagCommentNbr (elementName)?
	{
	pTagCommentElement.tagCommentNbr = $tagCommentNbr.text;
	pTagCommentElement.elementName = $elementName.text;
	}
	;

tagCommentNbr
	:
	'[' IntValue  ']'
	;
	
elementName
	:
	'.' alphaN
	;

IntValue 	
	:
	('0'..'9')+
	;

Including at least part of the grammar in question would probably be
very useful to anyone trying to help you.
