Validating and creating a XOM document using a default schema
Hi people. I'm having a problem that I really can't solve no matter how much time I spend on it and was wondering if it is possible.
I want to validate and create XOM documents. The xml will always be a certain format whether the schema is defined in the xml or not. I need to handle both cases.
When the xml has this in its first element:
<?xml version="1.0" ?>
<profile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="cardprofile3G.xsd" name="chineseCard" type="3G">
...
..
etc.
It works. But when I have this in the xml:
<?xml version="1.0" ?>
<profile name="chineseCard" type="3G">
...
..
etc.
It does not work. I get the exception:
nu.xom.ValidityException: cvc-elt.1: Cannot find the declaration of element 'profile'. at line 2, column 39

This is my code:
//InputStream inputStream = new FileInputStream(new File("C:\\Documents and Settings\\user\\My Documents\\chineseCard.xml"));
InputStream inputStream =new FileInputStream(new File("C:\\Documents and Settings\\user\\My Documents\\chineseCardNoSchema.xml"));
EntityResolver entityResolver =new ResourceEntityResolver("cardprofile3G.xsd","/com/user/resources/cardprofiler/cardprofile3G.xsd");
SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
saxParserFactory.setNamespaceAware(true);
XMLReader reader = saxParserFactory.newSAXParser().getXMLReader();
reader.setEntityResolver(entityResolver);
reader.setFeature("http://apache.org/xml/features/validation/schema",true);
Builder parser =new Builder(reader,true);
Document document = parser.build(inputStream);
Is there anyway I can check to see if a schema isn't defined in the xml and then add one if required?
I'm really stuck and would appreciate any help!
Thanks, Boomah.
By the way, I'm using Java 6 and XOM 1.1
