processSingle is no good for <loop> nodes where we want to work on the childNodes rather than the node itself
function(scope, member) {
        self.scope.push(scope);
        try {
          if (node.nodeName === 'LOOP') {
            for (var i = 0; i < node.childNodes.length; i++) {
              var clone = node.childNodes[i].cloneNode(true);
              processSingle(member, clone, node);
            }
          } else {
            var clone = node.cloneNode(true);
            clone.removeAttribute('foreach');
            processSingle(member, clone, node);
          }
        } finally {
          self.scope.pop();
        }
      }
