JAXP is
used for XML file processing in Java. To process an XML document or
to work with an XML document using Java you have to import namespace
like,
_______________________________________________
javax.xml.parsers.DocumentBuilderFactory
javax.xml.parsers.DocumentBuilder and
org.w3c.dom.Document etc.
A document
object has to be created to work with an XML document and the XML document
has to be loaded into that document object. This is one approach to
work with an XML file.
Creating
a document object involves a few steps. It is not direct. You need to
create a DocumentBuilderFactory object to load a DocumentBuilder object.
This DocumentBuilder object is used to a Document object. To process
the XML document thus loaded you can use SAX APIs and the XSLT APIs.
A lot of sample codes on these are available in the URL,
