// perhaps this could help:

Node.prototype.namespaceResolver = function(prefix) {
	swith(prefix){
		case 'soap': return 'http://schemas.xmlsoap.org/soap/envelope/';
		case 'xsi':  return 'http://www.w3.org/2001/XMLSchema-instance';
		case 'xsd':  return 'http://www.w3.org/2001/XMLSchema';
		case 'xul':  return 
'http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul';
	}
	return null;
}
Document.prototype.selectNodes =
Node.prototype.selectNodes = function(xpath) {
	var nodes = document.evaluate(xpath,this,this.namespaceResolver,0,null);
	var nodelist = new Array();
	var node = nodes.iterateNext();
	while( node ){nodelist.push( node );node = nodes.iterateNext();}
	return nodelist;
}
