Reading A Value From XML Node

I'm writing an app that makes an http request to my website and it returns a XML result set that looks like the following:

<ResultSet version="1.0">
<Status>
<code>0</code>
<message>Success</message>
<found>1</found>
</Status>
<Result>
<id>1115550003</id>
<distance>0.00</distance>
<compatibility>100</compatibility>
</Result>
</ResultSet>

I'm trying to read the <code> value but I'm having no luck. I can read the <message> value successfully and place that into a private string variable, but when I try to read the <code> value in the same manner, the getNodeValue() call is returning null. Below is my code...

Code:
public boolean xmlGetStatus(String response)
{
try
{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(response)));
[code]....
