RE: escaping from CDATA

Or even just do something that would work
function Fun(ctx) {
	var ipString = "";
	if (typeof(ctx) == "object"){
		if (ctx.length){
			ipString = ctx.nextNode.text;
		}else{
			return '';
		}
	}else{
		ipString = ctx;
	}
	var xml = new ActiveXObject("msxml2.domdocument");
	xml.loadXML(ipString);
	return xml.selectSingleNode("/");
}
