dom document

[Destramic]

im using dom to tidy up my html but i wondering is there a way to format my html like so

<dl>
     <dd>
            <label>Condition :</label>
            <select name="condition"><option value="New">New</option>
      </dd>
</dl>

insead of

<dl>
<dd>
<label>Condition :</label>
<select name="condition"><option value="New">New</option>
</dd>
</dl>

here is the php im using

$dom = new DOMDocument();
$dom->loadHTML($this->_body);
$dom->formatOutput = true;
echo $dom->saveHTML();

thank you
