How do I get an iterator for the one or more? The following doesn't quite seem
to work.
grammar Agenda;
options {language='Java';}
agenda :
l1=bill+ { Iterator it = $l1.iterator() ; } ;
bill returns[String xml] :
active fiscal title author NL
subject NL NL {
$xml = "<BILL>\n";
$xml += $title.xml + "\n";
$xml += $author.xml + "\n";
$xml += $subject.xml + "\n";
$xml += "</flag type=\"active\" status=\"" + $active.text +
"\">\n";
$xml += "</flag type=\"fiscal\" status=\"" + $fiscal.text +
"\">\n";
$xml += "</BILL>\n";
}
;
title returns [String xml] :
fifteen {
$xml="<Title>" + $fifteen.text + "</Title>";
};
author returns [String xml] :
ten {
$xml="<Author>" + $ten.text + "</Author>";
};
subject returns [String xml] :
ten {
$xml="<Subject>" + $ten.text + "</Subject>";
};
active : FLAG;
fiscal : FLAG;
fifteen : LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR;
ten : LTR LTR LTR LTR LTR LTR LTR LTR LTR LTR;
NL : ('\n'|'\r'|'\r\n');
FLAG : ('Y'|'N');
LTR : . ;
Input to the Lexer/Parser is the following.

make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
