Sun's JDK 6 uses SAX parser with a Stream Source. @ziggy - this is an implementation detail of the JAXP implementation.

The complete code listing for the Java-based XML validation tool discussed in this post is included at the end of the post. Validator is obtained from the /** * Validate provided XML against the provided XSD schema files.XML schema defines the elements that form an XML document. Validation is the process of verifying if the XML document complies to the defined schema definition. You also set a factory attribute to specify the parser language to use.(For SAX parsing, on the other hand, you set a property on the parser generated by the factory).Now that the program is ready to validate with an XML Schema definition, it is necessary only to ensure that the XML document is associated with (at least) one.

There are two ways to do that: , which stands for "XML Schema instance." The second line specifies the schema to use for elements in the document that do not have a namespace prefix-that is, for the elements you typically define in any simple, uncomplicated XML document.

The most significant lines of code from that application when discussing validation of XML against one or more XSDs is shown next. Schema Schema(Source[]) (where the array of transform. * * @param xml File Path And Name Path/name of XML file to be validated; * should not be null or empty.

package provides an API for XML documents validation.

Shouldn't execptions just be used for execptional situations and not for control flow? Also take a look at…In case someone gets error "No Schema Factory tha implements [...]", it's maybe because you did the same error as me, which was using the constant XMLConstants.

I wouldn't consider it execptional, if execute a 'test'.

Let us consider a simple XML file and the corresponding schema definition.
