DESCRIPTION
       The QXmlReader class provides an interface for XML readers (i.e.
       parsers).

       This abstract class provides an interface for all of Qt's XML readers.
       Currently there is only one implementation of a reader included in Qt's
       XML module: QXmlSimpleReader. In future releases there might be more
       readers with different properties available (e.g. a validating parser).

       The design of the XML classes follows the SAX2 Java interface, 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.

       All readers use the class QXmlInputSource 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 (QXmlDTDHandler, QXmlDeclHandler, QXmlContentHandler,
       QXmlEntityResolver, QXmlErrorHandler and QXmlLexicalHandler), which you
       must subclass, if you want to process the contents.

       Since the handler classes only describe interfaces you must implement
       all the functions. We provide the QXmlDefaultHandler 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.

       Features and properties of the reader can be set with setFeature() and
       setProperty() respectively. You can set the reader to use your own
       subclasses with setEntityResolver(), setDTDHandler(),
       setContentHandler(), setErrorHandler(), setLexicalHandler() and
       setDeclHandler(). The parse itself is started with a call to parse().

       See also QXmlSimpleReader and XML.

MEMBER FUNCTION DOCUMENTATION
QXmlDTDHandler * QXmlReader::DTDHandler () const [pure virtual]
       Returns the DTD handler or 0 if none was set.

       See also setDTDHandler().

QXmlContentHandler * QXmlReader::contentHandler () const [pure virtual]
       Returns the content handler or 0 if none was set.

       See also setContentHandler().

QXmlDeclHandler * QXmlReader::declHandler () const [pure virtual]
       Returns the declaration handler or 0 if none was set.

       See also setDeclHandler().

QXmlEntityResolver * QXmlReader::entityResolver () const [pure virtual]
       Returns the entity resolver or 0 if none was set.

       See also setEntityResolver().

QXmlErrorHandler * QXmlReader::errorHandler () const [pure virtual]
       Returns the error handler or 0 if none is set.

       See also setErrorHandler().

bool QXmlReader::feature ( const QString & name, bool * ok = 0 ) const [pure
       virtual]
       If the reader has the feature called name, the feature's value is
       returned. If no such feature exists the return value is undefined.

       If ok is not 0: *ok is set to TRUE if the reader has the feature called
       name; otherwise *ok is set to FALSE.

       See also setFeature() and hasFeature().

bool QXmlReader::hasFeature ( const QString & name ) const [pure virtual]
       Returns TRUE if the reader has the feature called name; otherwise
       returns FALSE.

       See also feature() and setFeature().

bool QXmlReader::hasProperty ( const QString & name ) const [pure virtual]
       Returns TRUE if the reader has the property name; otherwise returns
       FALSE.

       See also property() and setProperty().

QXmlLexicalHandler * QXmlReader::lexicalHandler () const [pure virtual]
       Returns the lexical handler or 0 if none was set.

       See also setLexicalHandler().

bool QXmlReader::parse ( const QXmlInputSource * input ) [pure virtual]
       Reads an XML document from input and parses it. Returns TRUE if the
       parsing was successful; otherwise returns FALSE.

       Example: xml/tagreader/tagreader.cpp.

bool QXmlReader::parse ( const QXmlInputSource & input ) [pure virtual]
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

void * QXmlReader::property ( const QString & name, bool * ok = 0 ) const
       [pure virtual]
       If the reader has the property name, this function returns the value of
       the property; otherwise the return value is undefined.

       If ok is not 0: if the reader has the name property *ok is set to TRUE;
       otherwise *ok is set to FALSE.

       See also setProperty() and hasProperty().

void QXmlReader::setContentHandler ( QXmlContentHandler * handler ) [pure
       virtual]
       Sets the content handler to handler.

       See also contentHandler().

       Example: xml/tagreader/tagreader.cpp.

void QXmlReader::setDTDHandler ( QXmlDTDHandler * handler ) [pure virtual]
       Sets the DTD handler to handler.

       See also DTDHandler().

void QXmlReader::setDeclHandler ( QXmlDeclHandler * handler ) [pure virtual]
       Sets the declaration handler to handler.

       See also declHandler().

void QXmlReader::setEntityResolver ( QXmlEntityResolver * handler ) [pure
       virtual]
       Sets the entity resolver to handler.

       See also entityResolver().

void QXmlReader::setErrorHandler ( QXmlErrorHandler * handler ) [pure virtual]

       Sets the error handler to handler. Clears the error handler if handler
       is 0.

       See also errorHandler().

void QXmlReader::setFeature ( const QString & name, bool value ) [pure
       virtual]
       Sets the feature called name to the given value. If the reader doesn't
       have the feature nothing happens.

       See also feature() and hasFeature().

       Reimplemented in QXmlSimpleReader.

void QXmlReader::setLexicalHandler ( QXmlLexicalHandler * handler ) [pure
       virtual]
       Sets the lexical handler to handler.

       See also lexicalHandler().

void QXmlReader::setProperty ( const QString & name, void * value ) [pure
       virtual]
       Sets the property name to value. If the reader doesn't have the
       property nothing happens.

       See also property() and hasProperty().
