How to retrieve only (not all) particular elements from XML using XStream (for an Android Web service)?

What is the best way to parse an XML file from a Web Service from a third-party in Android ?

It seems that with XStream, I need to define classes and attributes for everything in the XML. But I only want to use like 5% of the XML, is there a shorcut for this in XStream?

# Space.java
public class Space {
    String id = null;
    String name = null;
}

# Parsing Code
        XStream xs = new XStream(new XppDomDriver());
        xs.alias("space", Space.class);
        Space s = (Space) xs.fromXML( myXMLData );

# space.xml
<space>
  <can-join type="boolean">false</can-join>

Use SAXParser and DefaultHandler classes.
