What JavaScript libraries are there for creating forms using xml or json?

Question

ExtJS/Sencha

Need a tool to create forms dynamically with json or xml.
The project uses ExtJS.
There are settings files, for example:

{
  "title": "Список графиков пользователя",
  "buttons": [
    "Создать",
    "Редактировать"
  ],
  "grid": {
    "columns": [
      "Идентификатор",
      "Название графика"
    ]
  },
  "mess": "Выберите график"
}

All these settings need to be transferred to web forms. Now all settings are edited in json.
Found inputEx . But it uses YUI, and not such a rich interface as in ExtJS.

Answer 1

I advise you to pay attention to this library.
FancyForm
With more advanced functionality, it is provided as a module/standalone in the
FancyGrid project
