This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.) as defined below has been used in the code examples to validate the input document. You should not use the DOMParser to validate a document (unless your goal is to create a document object model anyway). W3C_XML_SCHEMA_NS_URI); try catch (SAXException e) catch (IOException e) but you could just as easily validate against a local file.The Extensible Markup Language (XML) has become the de facto standard data representation format for the Internet.XML data can be processed and interpreted on any platform--from handheld device to mainframe.The input document contains an extra attribute which has not been defined in the XML Schema, this shows that the XML Schema has been used for the validation.
Java is the winner programming language to use with XML.
@ziggy - this is an implementation detail of the JAXP implementation.
This will start creating DOM objects as it parses the document - wasteful if you aren't going to use them.
The Error Handler used for the examples is a very simple one which reports the error to and continues until the XML document has been fully parsed or until a fatal-error has been reported.
Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.
