Currently there is only one implementation of a reader +included in Qt's XML module: <a href="qxmlsimplereader.html">QXmlSimpleReader</a>. In future releases +there might be more readers with different properties available +(e.g. a validating parser). +<p> The design of the XML classes follows the <a href="http://www.saxproject.org/">SAX2 Java interface</a>, with +the names adapted to fit Qt naming conventions. It should be very +easy for anybody who has worked with SAX2 to get started with the +Qt XML classes. +<p> All readers use the class <a href="qxmlinputsource.html">QXmlInputSource</a> to read the input +document. Since you are normally interested in particular content +in the XML document, the reader reports the content through +special handler classes (<a href="qxmldtdhandler.html">QXmlDTDHandler</a>, <a href="qxmldeclhandler.html">QXmlDeclHandler</a>, +<a href="qxmlcontenthandler.html">QXmlContentHandler</a>, <a href="qxmlentityresolver.html">QXmlEntityResolver</a>, <a href="qxmlerrorhandler.html">QXmlErrorHandler</a> and +<a href="qxmllexicalhandler.html">QXmlLexicalHandler</a>), which you must subclass, if you want to +process the contents. +<p> Since the handler classes only describe interfaces you must +implement all the functions. We provide the <a href="qxmldefaulthandler.html">QXmlDefaultHandler</a> +class to make this easier: it implements a default behaviour (do +nothing) for all functions, so you can subclass it and just +implement the functions you are interested in. +<p> Features and properties of the reader can be set with <a href="#setFeature">setFeature</a>() +and <a href="#setProperty">setProperty</a>() respectively. You can set the reader to use your +own subclasses with <a href="#setEntityResolver">setEntityResolver</a>(), <a href="#setDTDHandler">setDTDHandler</a>(), +<a href="#setContentHandler">setContentHandler</a>(), <a href="#setErrorHandler">setErrorHandler</a>(), <a href="#setLexicalHandler">setLexicalHandler</a>() and +<a href="#setDeclHandler">setDeclHandler</a>().
