854 content of XML data.
855
856 \module XML
857
858 If the application needs to be informed of basic parsing events, it
859 implements this interface and sets it with QXmlReader::setContentHandler().
860 The reader reports basic document-related events like the start and end of
861 elements and character data through this interface.
862
863 The order of events in this interface is very important, and mirrors the
864 order of information in the document itself. For example, all of an element's
865 content (character data, processing instructions, and/or subelements) will
866 appear, in order, between the startElement() event and the corresponding
867 endElement() event.
868
869 The class QXmlDefaultHandler gives a default implementation for this
870 interface; subclassing from this class is very convenient if you want only be
871 informed of some parsing events.

1705 \class QXmlReader qxml.h
1706 \brief The QXmlReader class provides an interface for XML readers (i.e.
1707 parsers).
1708
1709 \module XML
1710
1711 This abstract class describes an interface for all XML readers in Qt. At the
1712 moment there is only one implementation of a reader included in the XML
1713 module of Qt (QXmlSimpleReader). In future releases there might be more
1714 readers with different properties available (e.g. a validating parser).
1715
1716 The design of the XML classes follow the
1717 <a href="http://www.megginson.com/SAX/">SAX2 java interface</a>.
1718 It was adopted to fit into the Qt naming conventions; so it should be very
1719 easy for anybody who has worked with SAX2 to get started with the Qt XML
1720 classes.
1721
1722 All readers use the class QXmlInputSource to read the input document from.
1723 Since you are normally interested in certain contents of the XML document,
1724 the reader reports those contents through special handler classes
1725 (QXmlDTDHandler, QXmlDeclHandler, QXmlContentHandler, QXmlEntityResolver,
1726 QXmlErrorHandler and QXmlLexicalHandler).
1727
1728 You have to subclass these classes. Since the handler classes describe only
1729 interfaces you must implement all functions; there is a class
1730 (QXmlDefaultHandler) to make this easier; it implements a default behaviour
1731 (do nothing) for all functions.
1732
