Sax validating dobson on dating
In this section we shall validate the example XML document with XML schema document catalog.xsd, with the SAXParser class. Create a SAXParser object and set the validation mode of the SAXParser object to SCHEMA_VALIDATION, as shown in the following listing: Validates the complete XML document with an XML schema if the parser is able to find a schema.
If the parser is not able find a schema or if the XML document does not conform to the schema, an error is raised.
One of the main advantages of validation is that we can combine it with standard parsers like SAX.
To turn on validation, you must request it explicitly.
SAXParser is recommended if SAX parsing event notification is required in addition to validation with a schema.
DOMParser is recommended if the DOM tree structure of an XML document is required for random access and modification of the XML document.
Schema Factory schema Factory = Schema Factory Instance(XMLConstants.
W3C_XML_SCHEMA_NS_URI); Schema schema = schema Schema(new File("myschema.xsd")); SAXParser Factory sax Factory = SAXParser Instance(); sax Schema(schema); SAXParser parser = sax SAXParser(); parser.parse("data.xml", new Default Handler() ); That isn't the behaviour I see (the parser always validates against the schema set on the factory, even if one is set in the document).Example bellow shows how to insert JAXP validation between source XML-file and SAX-parser: import
