Hi. I am parsing XML in javascript and it works fine in IE but not in Mizilla. The code I am using is

var newMenuRoot = parseXML(printNode(document.getElementById('NewMen u')), contextMenu);

contextMenu.replaceChild(newMenuRoot, contextMenu.firstChild);

   The question is what is the equivalent in Mozilla. I am using SVG, just in case. Any help would be apreciated. Thanks in advance. Greetings.
