I have an html document like this:

<div class="something">
   <textarea name="another"/>
   <div class="nested">
      <label>Nested Label</label>
      <input name="nested_input"/>
   </div>
</div>

I have gone through and modified some of the html tree by building it into a Nokogiri::HTML::Document like so:

html = Nokogiri::HTML(IO.read("test.html"))
html.children.each do ...

Now I want to be able to extract the nested part into a document so I can apply a stylesheet to it, or so I can manipulate it as if it were like a Rails partial. Something like this:

fragment = Nokogiri::HTML(html.xpath("//div[@class='nested']).first)

Is there a way to do that? Such a way that when I output it, it doesn't wrap it in<html> tags and turn it into an HTML document, I just want HTML, no document.

Is this possible?
