Class XMLCallbackWriter

  +--net.sourceforge.saxadapter.examples.roundtrip.XMLCallbackWriter

All Implemented Interfaces:

SAXTagHandler

public class XMLCallbackWriter

extends java.lang.Object

implements SAXTagHandler

This utility class writes the source document out to the Writer that is set in setWriter(). This is an example of how you can use the SAXAdapter to "round-trip" an XML document, which means parsing and writing out the document in a single pass.

                throws org.xml.sax.SAXException

Description copied from interface: SAXTagHandler

Called by the SAXAdapter when a start tag, for which this callback interface has been registered, has been encountered.

Specified by:

onStartTag in interface SAXTagHandler

Following copied from interface: net.sourceforge.saxadapter.SAXTagHandler

Parameters:

argTagNamespace - namespace URI of tag

argLocalTagName - unqualified tag name

argQName - qualified name of tag

argAttributes - tag attributes

argText - a StringBuffer that contains the text between the start and end tags.

argContext - the Map that represents parsing context. This context must be understood by each handler

argNamespaceContext - an interface that allows the handler to access namespace data associated with the current parsing state

Throws:

org.xml.sax.SAXException -

onEndTag
