/*!
  \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.

  The reader calls this function before he starts parsing the document. The
  argument \a locator is a pointer to a QXmlLocator which allows the
  application to get the actual position of the parsing in the document.

  Do not destroy the \a locator; it is destroyed when the reader is destroyed
  (do not use the \a locator after the reader got destroyed).
*/
/*!
  \fn bool QXmlContentHandler::startDocument()

  The reader calls this function when he starts parsing the document.
  The reader will call this function only once before any other functions in
  this class or in the QXmlDTDHandler class are called (except
  QXmlContentHandler::setDocumentLocator()).

  If this function returns FALSE the reader will stop parsing and will report
  an error. The reader will use the function errorString() to get the error
  message that will be used for reporting the error.

*/
/*!
  \fn bool QXmlContentHandler::endDocument()

  The reader calls this function after he has finished the parsing. It
  is only called once. It is the last function of all handler functions that is
  called. It is called after the reader has read all input or has abandoned
  parsing because of a fatal error.

  If this function returns FALSE the reader will stop parsing and will report
  an error. The reader will use the function errorString() to get the error
  message that will be used for reporting the error.

  \sa startDocument()

/*!
  \fn bool QXmlContentHandler::startPrefixMapping( const QString& prefix, const QString& uri )

  The reader calls this function to signal the begin of a prefix-URI
  namespace mapping scope. This information is not necessary for normal
  namespace processing since the reader automatically replaces prefixes for
  element and attribute names.

  Note that startPrefixMapping and endPrefixMapping calls are not guaranteed to
  be properly nested relative to each-other: all startPrefixMapping events will
  occur before the corresponding startElement event, and all endPrefixMapping
  events will occur after the corresponding endElement event, but their order
  is not otherwise guaranteed.

  The argument \a prefix is the namespace prefix being declared and the
  argument \a uri is the namespace URI the prefix is mapped to.

  If this function returns FALSE the reader will stop parsing and will report
  an error. The reader will use the function errorString() to get the error
  message that will be used for reporting the error.

  message that will be used for reporting the error.

  \sa startPrefixMapping()
*/
/*!
  \fn bool QXmlContentHandler::startElement( const QString& namespaceURI, const QString& localName, const QString& qName, const QXmlAttributes& atts )

  The reader calls this function when he has parsed a start element tag.

  There will be a corresponding endElement() call when the corresponding end
  element tag was read. The startElement() and endElement() calls are always
  nested correctly. Empty element tags (e.g. &lt;a/&gt;) are reported by
  startElement() directly followed by a call to endElement().

  The attribute list provided will contain only attributes with explicit
  values. The attribute list will contain attributes used for namespace
  declaration (i.e. attributes starting with xmlns) only if the
  namespace-prefix property of the reader is TRUE.

  The argument \a uri is the namespace URI, or the empty string if the element
  has no namespace URI or if namespace processing is not being performed, \a
  localName is the local name (without prefix), or the empty string if
  namespace processing is not being performed, \a qName is the qualified name
  (with prefix), or the empty string if qualified names are not available and
  \a atts are the attributes attached to the element. If there are no
  attributes, \a atts is an empty attributes object

  If this function returns FALSE the reader will stop parsing and will report
  an error. The reader will use the function errorString() to get the error
  message that will be used for reporting the error.

  The reader calls this function when he has parsed a chunk of character
  data (either normal character data or character data inside a CDATA section;
  if you have to distinguish between those two types you have to use
  QXmlLexicalHandler::startCDATA() and QXmlLexicalHandler::endCDATA() in
  addition).

  Some readers will report whitespace in element content using the
  ignorableWhitespace() function rather than this one (QXmlSimpleReader will
  do it not though).

  A reader is allowed to report the character data of an element in more than
  one chunk; e.g. a reader might want to report "a &amp;lt; b" in three
  characters() events ("a ", "<" and " b").

  If this function returns FALSE the reader will stop parsing and will report
  an error. The reader will use the function errorString() to get the error
  message that will be used for reporting the error.

  data of the processing instruction.

  \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>.
