title: jquery nested form plugin
body: <p>I am looking for a jQuery form plugin that can recive XML or json as an input to dynamiclly generate a nested form.
  For example:</p>
  
  <pre><code>&lt;root&gt;
  &lt;book&gt;
  &lt;title&gt;title 1&lt;/title&gt;
  &lt;price&gt;30&lt;/price&gt;
  &lt;/book&gt;
  &lt;book&gt;
  &lt;title&gt;title 2&lt;/title&gt;
  &lt;price&gt;50&lt;/price&gt;
  &lt;/book&gt;
  &lt;/root&gt;
  </code></pre>
  
  <p>Will be converted to:</p>
  
  <pre><code>&lt;form&gt;
  &lt;fieldset&gt;
  &lt;input type="text" name="title[0]"/&gt;
  &lt;input type="text" name="price[0]"/&gt;
  &lt;/fieldset&gt;
  &lt;fieldset&gt;
  &lt;input type="text" name="title[1]"/&gt;
  &lt;input type="text" name="price[1]"/&gt;
  &lt;/fieldset&gt;
  &lt;/form&gt;
  </code></pre>
