JDOM2 Android with Xerces

Installing and using Xerces in your Android project is relatively simple - but validating with it is not....

The default XMLReader is org.apache.harmony.ExpatReader. This class is loaded irrespective of whether your 'android dependencies' jar is before the android-core jar in your ecplipse classpath. I take it to mean that Android does not implement the JAXP process completely....

I have tried a number of different mechanisms for loading Xerces in such a way that it successfully can validate using XSD documents, and each attempt has failed. Here are the general details of each attempt.

As far as I can tell: Currently there is no working mechanism to do XML Schema validation on XML documents on Android

Please, please, please prove me wrong ... ;-)

Failed Attempt 1

So, the logical thing to do is to force the Xerces logic in to the process.... the following code attempts to load an XMLSchema validator that uses the 'internally refereced' xsd to validate a document.

	final SchemaFactory sfac = SchemaFactory.newInstance(
			"http://www.w3.org/2001/XMLSchema", 
			"org.apache.xerces.jaxp.validation.XMLSchemaFactory", 
			this.getClass().getClassLoader());
	final Schema schema = sfac.newSchema();

Unfortunately, the internal Xerces code (both 2.10 and 2.11) has, buried in it, a reference to StAX....

Failed Attempt 2

So, using the 'modern' mechanisms for specifying the XMLSchema are broken, but, what about using raw SAX2 methods?

	org.apache.xerces.parsers.SAXParser parser = new org.apache.xerces.parsers.SAXParser();

	parser.setFeature("http://xml.org/sax/features/validation", true); 
	parser.setFeature("http://apache.org/xml/features/validation/schema", true);
	parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true); 
			
	final URL url = this.getClass().getResource("input.xml");
	parser.setContentHandler(this);
	parser.parse(url.toExternalForm());

The above causes other sorts of problems....
