XML Schema Processors

This section describes XML Schema processors like Xerces2 and XML Spy.

In the previous section, we validated a XML document against an XSD schema manually without using any software tools. This manual validation process is doable only if the XML document and the XSD schema are simple.

But XML documents and XSD schema used in real applications are usually complex, and require software tools (XML Schema Processors) to help us to perform the validation.

What is XML Schema Processor? A XML Schema processor is a software tool that validates an XML document against an XSD schema.

XML Schema processor example 1 - Xerces2 Java Parser, which is the next generation of high performance, fully compliant XML parsers in the Apache Xerces family developed by The Apache Software Foundation.

XML Schema processor example 2 - XMLSpy, which is an XML editor and development environment for modeling, editing, transforming, and debugging XML-related technologies.

XML Schema processor example 3 - XMLPad, which is also an XML editor with XML Schema full support, including schema editing, schema validation, and XML validation.

See other chapters in this book for details on how to install and use Xerces2, XMLSpy, XMLPad and other XML Schema Processors.
