Many Java XML APIs provide mechanisms to validate XML documents, the JAXP API can be used for most of these XML APIs but subtle configuration differences exists.
) as defined below has been used in the code examples to validate the input document.
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.
The two most common types of nodes in XML document are element nodes and text nodes.
With Java DOM API we can create nodes, remove nodes, change their contents, and traverse the node hierarchy.
The Document Object Model standard is designed for XML documents manipulation. Java DOM Parser does not take advantage of Java's object-oriented features.
Text and elements is intermixed in a DOM hierarchy.To report errors, it is necessary to provide an Error Handler to the underlying implementation.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.Document parse Configuration(String resource Path) throws Exception /** * Parse a file containing an XML document, into a DOM object. * @param validating True iff validating should be turned on.* @return A DOM Object containing a parsed XML document or a null value ifthere is an error in parsing. * @throws Exception if parser can not be constructed or source is not a valid XML document.Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.
