Although a full treatment of XML Schema is beyond the scope of this tutorial, this section shows you the steps you take to validate an XML document using an XML Schema definition.
(To learn more about XML Schema, you can review the online tutorial, XML Schema Part 0: Primer.
This means that users who know XML are already familiar with XSD, eliminating the need to learn another language.
XML does not define any elements or tags that are usable within your document.
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.
SAXException; public class XMLValidation Employee validates against Employee.xsd? true Exception: cvc-elt.1: Cannot find the declaration of element ' Employee'.
Another positive aspect of having defined elements and data types, is that the information will be properly interpreted.
An XSD defines elements that can be used in the documents, relating to the actual data with which it is to be encoded.Shouldn't execptions just be used for execptional situations and not for control flow? Also take a look at stackoverflow.com/questions/15732/…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'. When using this XML Schema to validate the input XML document, the following error gets reported: ) as defined below has been used in the code examples to validate the input document.This section looks at the process of XML Schema validation.At the end of this section, you will also learn how to use an XML Schema definition to validate a document that contains elements from multiple namespaces.
