With BeautifulSoup it is as simple as:

from BeautifulSoup import BeautifulSoup
    html = """
      <body>
        <div class="mydiv">
          <p>i want got it</p>
          <div>
            <p> good </p>
            <a> boy  </a>
          </div>
        </div>
      </body>
    """

    soup = BeautifulSoup(html)
    result = soup.findAll('div', {'class': 'mydiv'})
    tag = result[0]
    print tag.contents
    [u'\n', <p>i want got it</p>, u'\n', <div>
    <p> good </p>
    <a> boy  </a>
    </div>, u'\n']

from BeautifulSoup import Tag; st = ''.join([str(t) for t in tag if type(t) == Tag]). Then write it: with open('somename.html', 'w') as f: f.write(st). Something like this

I would prefer lxml.html.

import lxml.html as H
doc  = H.fromstring(html)
node = doc.xpath("//div[@class='mydiv']")
