How to implement XML schema Verification by java
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
}
}
