This article mainly introduces java how to achieve XML schema verification, the article is very detailed, has a certain reference value, interested friends must read it!

The code is as follows:

The required JAR package needs to be downloaded by yourself (the version must be correct)

Public class SchemaValidation {

Public static void main (String [] args) {

Validate ()

}

Public static void validate () {

Try {

SchemaValidation demo = new SchemaValidation ()

/ / Give the xml and schema name

InputStream xmlString = demo.getClass () .getResourceAsStream ("GBAInit.xml")

InputStream schemaStr = demo.getClass () .getResourceAsStream ("GBAInitSchema.xsd")

SAXReader reader = createSAXReader (schemaStr)

System.out.println ("XSD parse successfully!")

Document document = reader.read (xmlString)

System.out.println ("Successfully validation...")

} catch (DocumentException e) {

System.out.println ("Exception occurred:" + e)

Throwable nestedException = e.getNestedException ()

If (nestedException! = null) {

System.out.println ("NestedException:" + nestedException)

NestedException.printStackTrace ()

} else {

E.printStackTrace ()

}

} catch (Throwable t) {

System.out.println ("Exception occurred:" + t)

T.printStackTrace ()

}

}

/ * * Registers the Verifier with the SAXReader * /

Protected SAXReader createSAXReader (InputStream schemaURI) throws Exception {

System.out.println ("Loaded schema document:" + schemaURI)

/ / use autodetection of schemas

VerifierFactory factory = new com.sun.msv.verifier.jarv.TheFactoryImpl ()

Schema schema = factory.compileSchema (schemaURI)

Verifier verifier = schema.newVerifier ()

Verifier.setErrorHandler (new ErrorHandler () {

Public void error (SAXParseException e) {

System.out.println ("ERROR:" + e)

}

Public void fatalError (SAXParseException e) {

System.out.println ("FATAL:" + e)

}

Public void warning (SAXParseException e) {

System.out.println ("WARNING:" + e)

}

});

/ / now install the verifying filter

VerifierFilter filter = verifier.getVerifierFilter ()

SAXReader reader = new SAXReader ()

Reader.setXMLFilter (filter)

Return reader

}

}
