Michael,
I finally understood your point (I could be slow sometimes ;o)). What I
have now:
- with LSParser:
// get DOM Implementation using DOM Registry
System.setProperty(DOMImplementationRegistry.PROPERTY,"org.apache.xerces
.dom.DOMXSImplementationSourceImpl");
DOMImplementationRegistry registry =
DOMImplementationRegistry.newInstance();
DOMImplementationLS impl =
(DOMImplementationLS)registry.getDOMImplementation("LS");
// create DOMBuilder
LSParser builder =
impl.createLSParser(DOMImplementationLS.MODE_SYNCHRONOUS, null);
DOMConfiguration config = builder.getDomConfig();
builder.setFilter(skipWhitespaceFilter);
// Create the document builder
JMSErrorHandler2 errorHandler = new JMSErrorHandler2();
config.setParameter("error-handler", errorHandler);
config.setParameter("schema-type",
"http://www.w3.org/2001/XMLSchema";);
config.setParameter("http://xml.org/sax/features/validation";, true);
config.setParameter("http://apache.org/xml/features/validation/schema";,
true);
config.setParameter("http://apache.org/xml/features/validation/schema/el
ement-default", true);
// Define the catalog resolver
XMLCatalogResolver catalog = new XMLCatalogResolver();
String[] catList = {System.getProperty("CATALOG")};
catalog.setCatalogList(catList);
// Set the prefere
catalog.setPreferPublic(true);
config.setParameter("resource-resolver", catalog);
// Parse the xml file
Document doc = null;
LSInput input = impl.createLSInput();
if (xml instanceof File) {
input.setByteStream(new
FileInputStream((File)xml));
} else if (xml instanceof String) {
input.setCharacterStream(new
StringReader((String)xml));
}
doc = builder.parse(input);
// Error checking
if ( errorHandler.validationError == true ) {
// errors occured during the parsing
if (myLogger.isInfoEnabled()) {
myLogger.info(funcName + "XML file is
not valid - Got a parsing error");
}
} else {
if (myLogger.isInfoEnabled()) {
myLogger.info(funcName + "XML file is
valid");
}
// Return the augmented document
TransformerFactory tFactory =
TransformerFactory.newInstance();
Transformer transformer =
tFactory.newTransformer();
DOMSource domSource = new DOMSource(doc);
StringWriter message = new StringWriter();
StreamResult streamResult = new
StreamResult(message);
transformer.transform(domSource, streamResult);
System.out.println(message.toString());
}
- With DOM factory:
// Create the dom factory
DocumentBuilderFactory domFactory =
DocumentBuilderFactory.newInstance();
// Set the namespace property
domFactory.setNamespaceAware(true);
// Ignore the comments
domFactory.setIgnoringComments(true);
// Eliminate whitespace in element content
domFactory.setIgnoringElementContentWhitespace(true);
domFactory.setCoalescing(true);
// Set the schema language property to be used for
validation
domFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaL
anguage", XMLConstants.W3C_XML_SCHEMA_NS_URI);
domFactory.setFeature("http://xml.org/sax/features/validation";, true);
domFactory.setFeature("http://apache.org/xml/features/validation/schema";
, true);
domFactory.setFeature("http://apache.org/xml/features/validation/schema/
element-default",true);
// Define the catalog resolver
XMLCatalogResolver catalog = new XMLCatalogResolver();
String[] catList = {System.getProperty("CATALOG")};
catalog.setCatalogList(catList);
// Set the prefere
catalog.setPreferPublic(true);
// Add the catalog to the document builder factory
domFactory.setAttribute("http://apache.org/xml/properties/internal/entit
y-resolver", catalog);
// Create the document builder
DocumentBuilder builder =
domFactory.newDocumentBuilder();
// Set an error handler
JMSErrorHandler errorHandler = new JMSErrorHandler();
builder.setErrorHandler(errorHandler);
// Parse the xml file
Document doc = null;
if (xml instanceof File) {
doc = builder.parse((File)xml);
} else if (xml instanceof String) {
doc = builder.parse(new InputSource(new
StringReader((String)xml)));
}
// Error checking
if ( errorHandler.validationError == true ) {
// errors occured during the parsing
if (myLogger.isInfoEnabled()) {
myLogger.info(funcName + "XML file is
not valid - Got a parsing error");
myLogger.info(funcName +
errorHandler.saxParseException.getMessage());
}
} else {
if (myLogger.isInfoEnabled()) {
myLogger.info(funcName + "XML file is
valid");
}
// Return the augmented document
TransformerFactory tFactory =
TransformerFactory.newInstance();
Transformer transformer =
tFactory.newTransformer();
DOMSource domSource = new DOMSource(doc);
StringWriter message = new StringWriter();
StreamResult streamResult = new
StreamResult(message);
transformer.transform(domSource, streamResult);
System.out.println(message.toString());
}
Both methods are parsing, validating and augmenting with default values
:o) If you see something wrong, please tell me.
Thx!!!
Lydie.

Michael,
Those 3 lines come from [1]:

rue);

I used the same features when I use a DOM factory. If you do not set all
those 3 to true, the element-default augmentation is not done. When
using LSParser, the augmentation is not done even if I use those 3
features. If I do something wrong, thx to help to correct my code. I am
quite new in this Java area.

Not sure what's going on but your use of the JAXP validation API is
completely unnecessary. You're already telling the LSParser to validate
the input.
