+ \class QXmlContentHandler qxml.h
+ \brief The QXmlContentHandler class provides an interface to report logical
+ content of XML data.
+
+ \module XML
+
+ If the application needs to be informed of basic parsing events, it
+ implements this interface and sets it with QXmlReader::setContentHandler().
+ The reader reports basic document-related events like the start and end of
+ elements and character data through this interface.
+
+ The order of events in this interface is very important, and mirrors the
+ order of information in the document itself. For example, all of an element's
+ content (character data, processing instructions, and/or subelements) will
+ appear, in order, between the startElement() event and the corresponding
+ endElement() event.
+
+ The class QXmlDefaultHandler gives a default implementation for this
+ interface; subclassing from this class is very convenient if you want only be
+ informed of some parsing events.

+ \class QXmlReader qxml.h
+ \brief The QXmlReader class provides an interface for XML readers (i.e.
+ parsers).
+
+ \module XML
+
+ This abstract class describes an interface for all XML readers in Qt. At the
+ moment there is only one implementation of a reader included in the XML
+ module of Qt (QXmlSimpleReader). In future releases there might be more
+ readers with different properties available (e.g. a validating parser).
+
+ The design of the XML classes follow the
+ <a href="http://www.megginson.com/SAX/">SAX2 java interface</a>.
+ It was adopted to fit into the Qt naming conventions; so it should be very
+ easy for anybody who has worked with SAX2 to get started with the Qt XML
+ classes.
+
+ All readers use the class QXmlInputSource to read the input document from.
+ Since you are normally interested in certain contents of the XML document,
+ the reader reports those contents through special handler classes
+ (QXmlDTDHandler, QXmlDeclHandler, QXmlContentHandler, QXmlEntityResolver,
+ QXmlErrorHandler and QXmlLexicalHandler).
+
+ You have to subclass these classes. Since the handler classes describe only
+ interfaces you must implement all functions; there is a class
+ (QXmlDefaultHandler) to make this easier; it implements a default behaviour
+ (do nothing) for all functions.
+
+ For getting started see also the
+ <a href="xml-sax.html#quickStart">Quick start</a>.
