XML Validation with Java

I have created a XML file with dom4j and the file confirmed to be valid when I read the file with Internet Explorer, a online XML validator and a free XML editor called "CookTop". However, when I attemp to read the XML file during the execution of an ant task I always get the XML parsing exception that one of my tag is not closed. I have even wrapped that test inside the tag as CDATA but that does not help as well. Do any one know what's happening? Here's my environment:
JDK: 1.4.2_05
Xerces: 2.6.2
Ant: 1.5.3
Thanks so much in advance.
I've been pumping my head into the wall for hours : p

Can i know where to download the CookTop?or CookTop2?

XML Validation with multiple XSD files (referenced)

Hello,
I know that XML validation with version 7.1 is possible now. However I was provided with a set of XSD files that have references to each other and need to be placed in a hierachical file system order so that references can be resolved.
An element <xsl:include schemaLocation="../../baseSchemas/baseSchema.xsd" /> is used for example. How can I handle that for XSD validation in PI? Can I create the same folder structure or do I need to put all XSD files in one directory and change the import manually?
But most important question: Is it possible it all to use more than one XSD for schema validation?

Dear Florian,
I had encountered such case in a project.
I was given 3 files. One main file and 2 others called Schema1.xsd and Schema2.xsd.
This happens because your data type is not in single namespace, but is being referred across namespaces and software components.
I am assuming that you have read the How to Guide for XML validations on PI 7.1
Best way to do this quickly is as follows.
1. Enable XML validation at adapter engine in the sender agreement.
2. Post a message using HTTP post. (http://sappihttpclient.codeplex.com)
3. Check communication channel in runtime workbench. There will be an error saying which is missing at what path.
4. Create the path mentioned and place the file at that path.
5. Repeat steps 2,3,4 for all the files.
When you are done with this, you will get a proper validation error in case XML file is not correct. And remember to generate XSD from message type and not data type.
Regards,
Vikas

XML validation with DTD in java 1.5 not supporting

Hi,
I am facing a problem regarding validation of xml file with DTD tag in it.
I have disabled the parser through setValidating(false) method.
xml file is not parsed in JRE 1.5.but it is parsed in JRE 1.6.
Why this is showing such a behavior?
I have used xerces 2.9.0,xml-api.jar and other jar regarding XML api but still it is giving error.
please help me.
please provide a jar file name or its issue resolution in jre 1.5 or 1.4.

thanks for your prompt reply.
I required that it should be completely disabled in jre 1.5(jdk1.5 or 1.4).
I am using DOM Parsing.I have currently disabled with follwowing method,
builderFactory.setValidating(false);
builderFactory.setFeature("http://xml.org/sax/features/validation",
     false);
     builderFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);
     builderFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd",false);
     builderFactory.setFeature("http://xml.org/sax/features/external-general-entities", false);
     builderFactory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
     factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
in 1.6 it is working fine but I required that i have to disabled it.but it is giving a error in jre1.5.
Exception in thread "main" java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V
I just want to disable the parsing in jdk version 1.5 or 1.4
thanks in advance

XML Validation with XSD in java mapping

Hi experts,
I have created an interface to send differents messages between bussines system, the bussiness system receiver is put in the message, to get this value I have a configuration file indicating the path of this field for each message type. In a java mapping I transform the message sent in this structure:
<document>
<message>HERE THE MESSAGE AS STRING</message>
<parameters>
<sender>HERE SENDER BUSSINESS SYSTEM</sender>
<receiver>HERE RECEIVER BUSSINESS SYSTEM</receiver>
</parameters>
</document>
the messaging interface works fine, but now I have to validate the XML vs XSD. I need doing in a java mapping because the messaging interface send the message and a email to sender in error case.
To do this validation I have implemented two java mappings that works fine in my local, the first way is with class Validator of java 5, but my system PI 7.1 return an error with this class. The second way is with SAX parse:
String schema = "XXXXXxsd";
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
docBuilderFactory.setNamespaceAware(true);
docBuilderFactory.setValidating(true);
docBuilderFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage","http://www.w3.org/2001/XMLSchema");
InputStream is = this.getClass().getClassLoader().getResourceAsStream(schema);
docBuilderFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource",is);
in my local works fine but in PI always return OK never fail.
For this moment the schema is hardcoded to do proofs, in the future will be loaded from my configuration file.
Any idea?
Thanks in advance
Jose

hi Jose,
PI 7.1 has a built in feature available called XML vaidations ..
your source xml can be validated against a XSD placed at a specific location on the PI server..
validation can be performed at adapter/integration engine

XML validation with JDOM / JAXP

Hello,
I am trying to validate xml file against schema file. I decided to use JDOM and JAXP.
First question: is it a good choice?
I did a first attempt but not sure I have understood all what I am doing :(
First I have create a parser usinf org.jdom.*
SAXBuilder parser = new SAXBuilderThen I built my document:
Document doc = parser.build(myFile)These 2 steps are ok. But it does not do validation.
I saw in the JDOM documentation that I can set a validation flag to true. I did it. First problem, I got the following error from JDOMException: Document is invalid: no grammar found.
Is there a way to specify to the parser where to find the xsd file?
As I did not find answer to this question by myself, I tried implementing the Schema class from JAXP:
SAXBuilder parser = new SAXBuilder;
Document doc = parser.build(myFile);
Schema schema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile);
ValidatorHandler vh = schema.newValidatorHandler();
SAXOutputter so = new SAXOutputter(vh);
so.output(doc);It does the validation against the schema file specified but I am not really sure about what I am doing here. The last 2 commands are not clear to me :(
Then in my schema file, I have elements that have default value. I expected the following behavior: if the element is not in the xml file then the default will be used by the parser (and added in the tree). But it seems, it's not the case.
Any help/explanation will be really appreciated.

If only schema validation is required use the validation API in JDK 5.0.

XML Validation with External XSD

XML validation with StAX

Hi,
I have a requirement to validate XMLs during JAXB unmarshalling and during StAX parsing. The schema is packaged in a jar. I am able to successfully read the schema, and validate the XML during unmarshalling by setting the schema in the unmarshaller (through setSchema()).
However, I am not able to validate it with StAX using the same schema and same XML.
Here is the code snippet for StAX:
StringReader stringReader = new StringReader(inputXMLStr);
XMLEventReader xmlEventReader = XMLInputFactory.newInstance().createXMLEventReader(stringReader);
EventFilter filter = new EventFilter() {
public boolean accept(XMLEvent event) {
return event.isStartElement();
XMLEventReader xmlFilteredEventReader = xmlif.createFilteredReader(xmlEventReader, filter);
Schema mySchema = getSchema(); // this method retrieves the schema by reading the schema files as
stream source and calling schemaFactory.newSchema(...)
Validator validator = mySchema.newValidator();
validator.setErrorHandler(new SchemaErrorHandler());
Source xmlSource = new StAXSource(xmlFilteredEventReader);
validator.validate(xmlSource);
I get a SAX Parse exception saying "cvc-elt.1: Cannot find the declaration of element 'myElement'"
And I also see the following exception:
Caused by: java.lang.NullPointerException
     at com.sun.org.apache.xalan.internal.xsltc.trax.StAXEvent2SAX.bridge(StAXEvent2SAX.java:171)

I am not able to figure out why the validation would work with UnMarshaller but not with StAX.
Any help appreciated.
Thanks
Meera

Have u tried the Stream STAX parser instead?
something like:
SchemaFactory factory = SchemaFactory
                         .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
File schemaLocation = new File(XSD_FILE_PATH);
               Schema schema = factory.newSchema(schemaLocation);
// 3. Get a validator from the schema.
Validator validator = schema.newValidator();
ErrorHandler lenient = new ForgivingErrorHandler(fw);
validator.setErrorHandler(lenient);
XMLInputFactory staxFactory = XMLInputFactory.newInstance();
staxFactory.setProperty(XMLInputFactory.IS_REPLACING_ENTITY_REFERENCES,
                         Boolean.TRUE);
staxFactory.setProperty(XMLInputFactory.IS_SUPPORTING_EXTERNAL_ENTITIES,
                         Boolean.FALSE);
staxFactory.setProperty(XMLInputFactory.IS_NAMESPACE_AWARE,
                         Boolean.TRUE);
staxFactory     .setProperty(XMLInputFactory.IS_COALESCING, Boolean.TRUE);
FileInputStream fis = new FileInputStream(XML_FILE_PATH);
XMLStreamReader xmlr = staxFactory.createXMLStreamReader(fis);
validator.validate(new StAXSource(xmlr));

Xml transformation with java

Hi, I am new to java, and was looking for some java code to accomplish the following:
I have an XML file, and a target XML schema. I also have a mapping schema, that maps the source xml file attributes with the target schema attributes.
I want to read the input xml file, and then reformat it to conform to the output xml schema(validated).
Will appreciate if someone can point me to code for a similar problem .....!

Transform the input xml to an XML document which conforms to the target schema with a XSLT.

XML Validation with no connection to the internet

Hi,
I'm trying to validate a ml instance document against a xml schema, using the javax.xml.validation.Validator.validate() method. This works fine as long as I have an internet connection, but not when I disconnect from the internet it fails.
I've detected, using a network sniffer, that this is due to the fact that the validation process tries to fetch the XMLSchema.dtd and datatypes.dtd from w3.org. Is there any way to avoid this by prestoring these somewhere? So that the internet connection is not needed?
I need to be able to do validation without a connection to the internet since the environment where my application is deployed does not have such a connection.
Ray

Hi Ray,
Were you able to resolve this issue? I am encountering a very similar problem where I am not connected to the internet and it fails during the newSchema method on javax.xml.validation.SchemaFactory. I have attempted to implement the suggestions of ExtremeGardener and vidyut with no luck.
Per ExtremeGardener's suggestion of replacing xmlns:xs="http://www.w3.org/2001/XMLSchema" with xmlns:xs="XMLSchema.xsd" and storing it locally, it gave me an error for trying to set the "xs" or "xsd" prefixes to anything other than "http://www.w3.org/2001/XMLSchema." I forget the exact error. I also tried to use my own prefix and it did not like that either.
Per vidyut's suggestion of using a catalog resolver, I believe that I have tried that too (if I understand correctly). I created an LSResourceResolver and tied it to the SchemaFactory. I can invoke it for a namespace but that did not resolve the issue because it only invokes the resolver on an import, include, or redefine. I believe that it is trying to reach the internet due to the xmlns:xs="http://www.w3.org/2001/XMLSchema" attribute within the top-level schema element in the XSD and I know of no way to invoke it for that.
I also created an ErrorHandler and tied it to the SchemaFactory. That shows me the errors and they are all related to the standard XML data types defined in XMLSchema.xsd. The errors that I am seeing are all of this form: "UndeclaredPrefix: Cannot resolve 'xs:string' as a QName: the prefix 'xs' is not declared."
I am currently using the SchemaFactory in Java 1.5, but I am thinking about trying the Xerces SchemaFactory since they are not exactly the same implementation.
Does anyone have any other suggestions? Any help you can provide would be greatly appreciated!
Thanks,

How to validate the Xml File With Java

Hi,
Can pls tell me. I want to validate the XML File for the Some Mandartory TAG. if that if Tag null i want to generate error xml file with error and i want move another folder with java. pls help me as soon as possible

Use a validating parser (any recent Xerces, for one) and switch on the validation feature. Very much vendor-specific, so look at the docs of your parser. Oh, you do have a schema for these documents, don't you?

XML Validation with DTD... Urgent

Hi all,
I am using java 1.4
I have to validate the XML file with the external DTD.
Can anyone give me the code for that.
DTD should be external.
Thanks,
Vinayak.

If you are using Solaris , it has xml validation tool "xmllint", using this you can validate your xml against DTD.
try with "xmllint --help " to see all the option.

Can you please help me to figure out this problem?

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);
