Default values with grammars 2003-05-29 - By Ron Rothblum
This is the code for parsing both the schema and the xml:
public static void preParseSchema(final InputStream schema) throws
AmtParseException {
grammarPool = new XMLGrammarPoolImpl();
XMLGrammarPreparser preparser = new XMLGrammarPreparser();
ParserErrorHandler errHandler = new ParserErrorHandler();
preparser.registerPreparser(XMLGrammarDescription.XML_SCHEMA, null
);
preparser.setProperty(GRAMMAR_POOL, grammarPool);
preparser.setFeature(NAMESPACES_FEATURE_ID, true);
preparser.setFeature(VALIDATION_FEATURE_ID, true);
preparser.setFeature(SCHEMA_VALIDATION_FEATURE_ID, true);
preparser.setFeature(SCHEMA_FULL_CHECKING_FEATURE_ID, true);
preparser.setFeature(SCHEMA_ELEMENT_DEFAULT_ID, true);
preparser.setFeature(SCHEMA_NORMALIZED_VALUE_ID, true);
preparser.setErrorHandler(errHandler);
// parse the grammar...
XMLInputSource inputSource = new XMLInputSource(null,null,null
,schema,null);
try {
preparser.preparseGrammar(XMLGrammarDescription.XML_SCHEMA, inputSource);
} catch (IOException e) {
throw new AmtParseException(new ParserError("","",""
,e.getMessage()));
} catch (XMLParseException e) {
//A fatal error has occured and will be reported through
the error handler
}
if (errHandler.hasParseErrors())
throw new AmtParseException(errHandler.getParseErrors());
}
/**
* Creates a DOM tree, validates according to the schema in the
grammer pool.
* @(protected) newSet the file to be parsed
* @(protected) AmtParseException when errors occured.
*/
public static synchronized Document toDomTree(final InputStream
newSet){
DOMLineParser parser = new DOMLineParser();
ParserErrorHandler errHandler = new ParserErrorHandler();
// attempt to activate desired features
try{
//validate the xml definition according to the dtd/xml schema
parser.setFeature(NAMESPACES_FEATURE_ID, true);
parser.setFeature(SCHEMA_VALIDATION_FEATURE_ID, true);
parser.setFeature(SCHEMA_FULL_CHECKING_FEATURE_ID, true);
parser.setFeature(SCHEMA_ELEMENT_DEFAULT_ID, true);
parser.setFeature(SCHEMA_NORMALIZED_VALUE_ID, true);
parser.setFeature(VALIDATION_FEATURE_ID, true);
parser.setFeature(DEFERRED_NODE_EXPANSION_ID, false);
if (grammarPool!=null)
parser.setProperty(GRAMMAR_POOL, grammarPool);
}catch (SAXException se) {
throw new AmtParseException(new ParserError("","",""
,se.getMessage()));
}
parser.setErrorHandler(errHandler);
InputSource in=new InputSource(newSet);
try {
