How can I parse a namespace using the SAX parser?

Hello,
Using a twitter search URL ie. http://search.twitter.com/search.rss?q=android returns CSS that has an item that looks like:
<item>
<title>@UberTwiter still waiting for @ubertwitter android app!!!</title>
<link>http://twitter.com/meals69/statuses/21158076391</link>

Pretty simple. My code parses out everything (title, link, description, pubDate, etc.) without any problems. However, I'm getting null on:
<google:image_link>
I'm using Java to parse the RSS feed. Do I have to handle compound localnames differently than I would a more simple localname?
This is the bit of code that parses out Link, Description, pubDate, etc:
@Override
public void endElement(String uri, String localName, String name)
throws SAXException {
super.endElement(uri, localName, name);
if (this.currentMessage != null){
if (localName.equalsIgnoreCase(TITLE)){
currentMessage.setTitle(builder.toString());
} else if (localName.equalsIgnoreCase(LINK)){
currentMessage.setLink(builder.toString());
} else if (localName.equalsIgnoreCase(DESCRIPTION)){
currentMessage.setDescription(builder.toString());
} else if (localName.equalsIgnoreCase(PUB_DATE)){
currentMessage.setDate(builder.toString());
} else if (localName.equalsIgnoreCase(GUID)){
currentMessage.setGuid(builder.toString());
} else if (uri.equalsIgnoreCase(AVATAR)){
currentMessage.setAvatar(builder.toString());
} else if (localName.equalsIgnoreCase(ITEM)){
messages.add(currentMessage);
}
builder.setLength(0);
}
}
startDocument looks like:
@Override
public void startDocument() throws SAXException {
super.startDocument();
messages = new ArrayList<Message>();
builder = new StringBuilder();
}
startElement looks like:
@Override
public void startElement(String uri, String localName, String name,
Attributes attributes) throws SAXException {
super.startElement(uri, localName, name, attributes);
if (localName.equalsIgnoreCase(ITEM)){
this.currentMessage = new Message();
}
}
