Just an idea - tested in FF/Safari - seems to work if you create an iframe to store the document temporarily. Of course, if you are doing this it might be smarter to just use the src property of the iframe to load the document and do whatever you want in the "onload" of it.
  $(function() {
    $.ajax({
      type: 'GET', 
      url: 'result.html',
      dataType: 'html',
      success: function(data) {
        var $frame = $("").hide();
        $frame.appendTo('body');
        var doc = $frame.get(0).contentWindow.document;
        doc.write(data);
        var $title = $("title", doc);
        alert('Title: '+$title.text() );
        $frame.remove();
      }
    });
  });
</code></pre>

<p>I had to append the iframe to the body to get it to have a .contentWindow.</p>

             <div class="appendcontent">
                                                        </div>
            </div>
            <div class="jieda-reply">
              <span class="jieda-zan button_agree" type="zan" data-id='413482'>
                <i class="iconfont icon-zan"></i>
                <em>0</em>
              </span>
                   <span type="reply" class="showpinglun" data-id="413482">
