XOM API for Processing XML with Java

[ Note the Xerces DOMParser.parse() method expects the document's System 
ID (a string that points to the document's location), not the document's 
contents as a string ]

There's a DOMConverter class in the nu.xom.converters package for just 
this purpose.  The only tricky part is that you have to supply a 
concrete W3C DOMImplementation object.  A JAXP-friendly way to get a 
DOMImplementation object is illustrated in the unit tests for the 
DOMConverter class:

nu.xom.Document xomDoc;
// populate the XOM Document


// straight cut n' paste
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
builder = factory.newDocumentBuilder();
impl = builder.getDOMImplementation();

org.w3c.dom.Document domDoc = DOMConvertor.convert(xomDoc, impl);
