This may involve storing the data into a database or writing it out to a stream.
During parsing, the parser may need to access external documents.
Sun's JDK 6 uses SAX parser with a Stream Source.
@ziggy - this is an implementation detail of the JAXP implementation.
Processing an XML document means recognizing, extracting and directly processing the element contents and attribute values or mapping them to other business objects that are processed further on.
Before an application can apply any business logic, the following steps must take place: Parsing XML documents implies a lot of character encoding and decoding and string processing.
If you use a DOM parser explicitly for validation, you will definitely instantiate a DOM tree.// parse an XML document into a DOM tree Document Builder parser = Document Builder Instance()Document Builder(); Document document = parser.parse(new File("instance.xml")); // create a Schema Factory capable of understanding WXS schemas Schema Factory factory = Schema Instance(XMLConstants. If I use an Error Handler (own class that implements Error Handler) instead, it recognizes all errors, but the try-catch-block of validator.validate does not throw any Exception.. The definition of the dtd and xsd has to be in the xml! If you are generating XML files programatically, you may want to look at the XMLBeans library.
W3C_XML_SCHEMA_NS_URI); // load a WXS schema, represented by a Schema instance Source schema File = new Stream Source(new File("my Schema.xsd")); Schema schema = Schema(schema File); // create a Validator instance, which can be used to validate an instance document Validator validator = Validator(); // validate the DOM tree try catch (SAXException e) Working this way, a SAXException would be thrown at the first error in the xml-file and stops then the validation. How do I recognize an error in the class that invokes the validate-method of my validator? Using a command line tool, XMLBeans will automatically generate and package up a set of Java objects based on an XSD.
The application moves the cursor forward - 'pulling' the information from the parser as it needs.
This is different from an event based API - such as SAX - which 'pushes' data to the application - requiring the application to maintain state between events as necessary to keep track of location within the document.
XML processing is very CPU, memory, and I/O or network intensive.
