Validating with a Schema

I know this should not be difficult, but I cannot really find an easy answer to validating an XML document against a schema. I have an XML document that I can validate against a schema within Netbeans. I want to write some Java code that will validate the XML document against the schema at runtime before I start reading the data. Can someone provide me with a simple straightforward answer? Does the XML document have to have the "xsi:schemaLocation" or can I define that at code time?
I am currently using the DocumentBuilderFactory, DocumentBuilder, and Document to load the XML into a DOM document so that I can read the data.
Thanks

Validating with multiple schemas

I am setting the schama attribute as follow:
String schemaSource = "C:\\Documents and Settings\\ayache\\My Documents\\C5 XML\\schema\\searhRequest.xsd";
String JAXP_SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
builderFactory.setAttribute(JAXP_SCHEMA_SOURCE, new File(schemaSource));searchRequest.xsd contains include statement: it referes to another schema. When i try to validate the xml document using the scheam above error is thrown stating that the elements that are defined in the second schema(BookingProfile.xsd) are not recognised or can't be resolved.
Is there a way to set multiple schemas?
Your help is much appreciated.

I figured out my problem in case anyone else is having trouble..
In the xml document that you need to refer to:
xmlns:xsd="http://www.w3.org/2000/10/XMLSchema-instance that is the namespace
supported by xerces 1.3.1.

Validation with XML Schema

With the Xerces parser, you can validate an XML document against an XML schema. But what I wanted to do is something different.
I want to validate data before they are put in XML. Like this:
1) I have a set of class/classes that act as helper class(es) that creates an XML document that conforms to a specific XML Schema. The class(es) would have, of course, setXXXX() methods in it. The XML document is not created until someone call create().
2) With each setXXXXX() method call, I know that the setXXXXX() would eventually map to a specific attribute in a specific element in the XML document that will be created.
3) Therefore, I would want to be able to throw an Exception if a developer call setXXXX() with the correct Java data type, but with an incorrect value based on the XML Schema .... instead of throwing the error when the XML is being serialized / created by the XML parser in the create() method.
Any ideas on how to do this?
Regards,
John

The only way that I could think to do this is to have
a lot of XSDs, one for each element essentially.
In this case you'd have to build your mini-XMLs, parse
each one with an XSD, and then report the error.
Why do you want to do it this way? Is it because you
want to know exactly which one gave an error without
having to parse through the sometimes cryptic error
messages?
PaulYes. that's one.
The other is, if you think of a form that is being filled by a user, you would want the user to be informed of which field in the form has the incorrect value, instead of just showing a generic message .... after which the user may get fed up and do his business elsewhere. Not good for business, isn't it?

XML: VALIDATING WITH XML SCHEMA: SAXNotRecognizedException

Hi,
1. From The Java� Web Services Tutorial for SAX
If the parser is not 1.2 compliant, and therefore does not support XML Schema,it could throw a SAXNotRecognizedException .
SAXParser saxParser =factory.newSAXParser();
try {
saxParser.setProperty(JAXP_SCHEMA_LANGUAGE,W3C_XML_SCHEMA);
catch (SAXNotRecognizedException x){
//Happens if the parser does not support JAXP 1.2
2. How do we know if the parser is not 1.2 compliant or not? 1M Thanks.

If you have an older xerces.jar in your class path your parser will not be JAXP 1.2 compliant.
Try replacing xerces.jar with both xercesImpl.jar and xml-apis.jar.

Xml validation with xml schema

Hi
I want to do the validation of a xml file against the XML schema.How can i do that.
As per jaxp we can do the validation of an xml file against DTD ,CAN we do the validation against XMLschema in a same way.
Please help its urgent.
regards
prateek

if you're using the Xerces parser, you def. can.
if u look at the SAXCount example, you'll see a certain amount of attributes are set to true/false.
one of these is Schema validation. set it to true, run the SAXCount.java example, and your XML is validated against it's XML Schema,

How to validate an xml with a schema w/o specifying the schema in the xml

I have done xml validation with xml schemas, where the xml points to the xsd to use. However, I would like to not have to specifiy the xml schema in the xml document (and can't ensure that the xml coming to us has that in it). How do I, in the java code, tell it what schema to use in validation?
Brian

static final String schemaSource = argv[0];
static final String JAXP_SCHEMA_SOURCE =
"http://java.sun.com/xml/jaxp/properties/schemaSource";
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
factory.setAttribute(JAXP_SCHEMA_SOURCE,
new File(schemaSource));

Catch all error information while validating xml content with xsd schema

Hi experts,
I created a java mapping to validating the input xml content with xsd schema (schema validation). What I want is to catch all error message to the xml not just the first error. I used SAXParser in sapxmltoolkit.jar to do the schema validation. The below is a part of my java mapping.
XMLReader parser = XMLReaderFactory.createXMLReader("com.sap.engine.lib.xml.parser.SAXParser");
parser.setFeature( "http://xml.org/sax/features/validation" , true);
parser.setFeature( "http://apache.org/xml/features/validation/schema" , true);
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");          parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",this.getClass().getClassLoader().getResourceAsStream(schema)); // schema is my schema name
parser.setErrorHandler(new ParseErrorHandler()); // ParseErrorHandler is my own ErrorHandler which extends DefaultHandler
parser.parse(new InputSource(new ByteArrayInputStream(sinput.getBytes())));
// In error handler, I comment all code so as not to throw any exception
public class ParseErrorHandler extends DefaultHandler
     public void error(SAXParseException e) throws SAXException
          // sSystem.out.println("Error" + e.getMessage());
          // throw e;
     public void fatalError(SAXParseException e)
          // throw e;
          // System.out.println("SAP Fatal Error" + e.getMessage());

Validation with jaxp 1.3 and xml-schema

I'm totally green when it comes to xml&jaxp. Using jse 1.5 (jaxp 1.3), I'm trying
to have my app parse and validate an xml doc with xml schema. I want the validation to
happen using the schema specified in the xml doc. Also, I'd prefer if my application didn't have to set
the schema to use. As far as I can make out though, it appears that I need to parse the schemaLocation when
I want to validate using xml schema. Anyone know a way to avoid that step?
If not, then any idea why I'm getting the following err?

     where com.rwd.util.xml.Validator extends DefaultHandler. Note that if I add following

     I would anticipate being able to have the parser see the XSD reference in the XML and
     apply it. Anyway, here's code to programmatically specify an XSD to use for validation....
     documentFactory.setAttribute(

With XMLBeans, an XML document may be created from and validated with an XML schema.

Schema Validation with Java and Document object

Hi, I am working on a project that will validate an xml Document object from a child class. I seem to have completed XSD validation with new DOMSource(doc) and using schema factory, which doesn't support DTD validation. And now I am attempting to validate the DTD. It seems like all the examples I've seen are trying to parse files, and I am struggling with finding a way to validate it directly against the document object.
The child class creates the xml document which is passed back to the parent class, and I need to do the validation in the parent class, so I need away to validate against the document object. This will be an assertion in Fitnesse if anyone is familar with it.
private void doSchemaValidationCommand(int rowCount, Document doc, String xpathExpression)
         String validationPath = getText(rowCount,1);
         String extensionSeparator = ".";
         Boolean error = false;
         String ext = null;
         try
         int dot = validationPath.lastIndexOf(extensionSeparator);
        ext = validationPath.substring(dot + 1);
         catch(Exception e)
              this.wrong(rowCount, 1, e.getMessage());
         if (ext.equalsIgnoreCase("xsd"))
         try {
         SchemaFactory factory =
            SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        File schemaLocation = new File(validationPath);
        Schema schema = factory.newSchema(schemaLocation);
        Validator validator = schema.newValidator();
        try {
            validator.validate(new DOMSource(doc));
        catch (SAXException ex) {
            this.wrong(rowCount, 1, ex.getMessage());
            error = true;
        catch (IOException ex) {
             this.wrong(rowCount, 1, ex.getMessage());
             error = true;
       catch (SAXException ex) {
           this.wrong(rowCount, 1, ex.getMessage());
           error = true;
       catch (Exception ex){
            this.wrong(rowCount, 1, ex.getMessage());
            error = true;
         else if (ext.equalsIgnoreCase("dtd"))
              try {
         }

I tried this but it doesn't give me any validation of whether or not it was completed successfully, it just adds a tag for the dtd to the xml and doesn't seem to do anything further with it, am I missing any steps?
else if (ext.equalsIgnoreCase("dtd"))
              try {
                   DOMSource source = new DOMSource(doc);
                   StreamResult result = new StreamResult(System.out);

                   Transformer transformer = tf.newTransformer();
                   transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, validationPath);
                   transformer.transform(source, result);
              catch(Exception e)
                   this.wrong(rowCount, 1, e.getMessage());

"personally, I'd just put the exception handling into the package."
Maybe I am making this over-complicated. I would like all the error handling in the package. It seems like putting an ONSERVERERROR trigger would be a little overkill, and if it fires on every database error, and I have to screen for only my errors seems like a little overkill and to me, it seems like it would incur quite a bit of overhead for the database seeing it is firing for every error. I don't even know if I would ultimately be allowed to keep it.
Really, all I would want to do is:
1) Handle the error and recover if possible
2) If it is a fatal error, have a way to abort the package gracefully with some kind of record of it.
3) Allow for the possibility of non-fatal errors or messages, even that I might generate myself to be able to be logged.
This package has about 20 procedures now. If I have an error (particularly fatal), in let's say, procedure 8, I don't even know what happens. I don't know if by default it aborts the whole package or just that procedure or just keeps going. Is it possible to get just hung up and sit there?
Thanks for the input.

Xerces2_6_2 validating with dtd and schema.. please help

Hi I am having trouble validating an xml document using xerces2_6_2
I have a DTD that containes only entity references, and a schema that is used to ensure the xml is valid.
I get this error.
Element type "my root tag" must be declared!
It seems to expect all validation grammer to be in the dtd. I have sucessfully validated with xml spy and oxygen,(oxygen uses xerces too).
This is a real pain I really would lie to take advantage of using schemas, I know I could just use entity references in this form and not have a dtd but this is really not acceptable.
I have tried out all the xerces specific properties and features but this has not worked either.
Perhaps I should implement a validator? Does anyone have any ideas?
thanks

My solution, I thought to take, wasn't the right way, but I have found following thread within the forum
http://forum.java.sun.com/thread.jspa?forumID=34&threadID=527461
The problem you have described points to a dtd error. Considering the thread above, it would make sense. It is a presumption, but perhaps that is because of the new Xerces version. I would try with an older one.
Sorry, that I could help you along.

Please help me out

--> Could not find cached enumeration value Custom.CI.Enum.PeripheralDevice.Printer for property Type, class BMC.Custom.CI.PeripheralDevice in enumeration cache.
You must specify either the Name or Guid of an enumeration of type Custom.CI.Enum.PeripheralDevice.Type.
Be sure that you are specifying the Name property of the enumeration value you want to set, and not the DisplayName; the Internal Name is something like "IncidentCategoryEnum.Category" for out of the box enumerations, or ENUM.210ADA2282FDABC3210ADA2282FDABC
for enumerations created in the console.
you can check this by finding the enumeration in the XML or by using the the
SMLets commandlet
Get-SCSMEnumeration | ?{$_.DisplayName –eq “Printer”}
and then checking your value with
Get-SCSMEnumeration -Name "ENUM.210ADA2282FDABC3210ADA2282FDABC"
and see if you get the right displayname back
