DOMDocument-> saveHTML () space conversion

In my code I have

$document = DomDocument->loadHTML($someHTML);
$xPath = new DOMXPath($document);
//
//do some xpath query and processing
//
$result = $document->saveHTML();

The html I am processing contains:

<html>
<body>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;line-height:
normal;text-autospace:none"><b><span style='font-size:9.0pt;font-family:"ArialNarrow","sans-serif";
color:red'>&nbsp;</span></b></p>
</body>
</html>

and leads to:

<html>
<body>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;line-height:
normal;text-autospace:none"><b><span style='font-size:9.0pt;font-family:"ArialNarrow","sans-serif";
color:red'> </span></b></p>
</body>
</html>

How to prevent &nbsp;from converting to empty space?
