Xml validating in dom parser
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.
Validation can be indirect: if the structure contains a reference to a DTD file that itself contains a reference to an XSD file, the command will attempt to carry out both validations.
The third parameter is used to indicate a specific DTD or an XML schema for document parsing.
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.
If you use this parameter, the command does not take the DTD referred to in the XML document into account.
Validation by DTDThere are two ways to specify a DTD: Validation by schema To validate the document via an XML schema, you just need to pass a file or URL with an “xsd” extension instead of a “dtd” one in the third parameter.
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).

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.
