+    \class QXmlParseException
+    \reentrant
+    \brief The QXmlParseException class is used to report errors with
+    the QXmlErrorHandler interface.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+
+    The XML subsystem constructs an instance of this class when it
+    detects an error. You can retrieve the place where the error
+    occurred using systemId(), publicId(), lineNumber() and
+    columnNumber(), along with the error message(). The possible error
+    messages are:
+
+
+    \list
+        \o "no error occurred"
+        \o "error triggered by consumer"
+        \o "unexpected end of file"
+        \o "more than one document type definition"
+        \o "error occurred while parsing element"
+        \o "tag mismatch"
+        \o "error occurred while parsing content"

+    UTF-8 or UTF-16, depending on whether it can find a byte-order
+    mark.
+
+    There are two ways to populate the input source with data: you can
+    construct it with a QIODevice* so that the input source reads the

+    \class QXmlContentHandler
+    \reentrant
+    \brief The QXmlContentHandler class provides an interface to
+    report the logical content of XML data.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+
+    If the application needs to be informed of basic parsing events,
+    it can implement this interface and activate it using
+    QXmlReader::setContentHandler(). The reader can then report 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 sub-elements) appears, in order, between the
+    startElement() event and the corresponding endElement() event.
+
+    The class QXmlDefaultHandler provides a default implementation for
+    this interface; subclassing from the QXmlDefaultHandler class is
+    very convenient if you only want to be informed of some parsing
+    events.
+
+    The startDocument() function is called at the start of the
+    document, and endDocument() is called at the end. Before parsing
+    begins setDocumentLocator() is called. For each element
+    startElement() is called, with endElement() being called at the
+    end of each element. The characters() function is called with
+    chunks of character data; ignorableWhitespace() is called with
+    chunks of whitespace and processingInstruction() is called with
+    processing instructions. If an entity is skipped skippedEntity()
+    is called. At the beginning of prefix-URI scopes
+    startPrefixMapping() is called.

+    \class QXmlDefaultHandler
+    \reentrant
+    \brief The QXmlDefaultHandler class provides a default implementation of all
+    the XML handler classes.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+
+    This class gathers together the features of
+    the specialized handler classes, making it a convenient
+    starting point when implementing custom handlers for
+    subclasses of QXmlReader, particularly QXmlSimpleReader.
+    The virtual functions from each of the base classes are
+    reimplemented in this class, providing sensible default behavior
+    for many common cases. By subclassing this class, and
+    overriding these functions, you can concentrate
+    on implementing the parts of the handler relevant to your
+    application.
+
+    The XML reader must be told which handler to use for different
+    kinds of events during parsing. This means that, although
+    QXmlDefaultHandler provides default implementations of functions
+    inherited from all its base classes, we can still use specialized
+    handlers for particular kinds of events.
+
+    For example, QXmlDefaultHandler subclasses both
+    QXmlContentHandler and QXmlErrorHandler, so by subclassing
+    it we can use the same handler for both of the following
+    reader functions:
+
+    \snippet doc/src/snippets/xml/rsslisting/rsslisting.cpp 0
+
+    Since the reader will inform the handler of parsing errors, it is
+    necessary to reimplement QXmlErrorHandler::fatalError() if, for
+    example, we want to stop parsing when such an error occurs:
+
+    \snippet doc/src/snippets/xml/rsslisting/handler.cpp 0
+
+    The above function returns false, which tells the reader to stop
+    parsing. To continue to use the same reader,
+    it is necessary to create a new handler instance, and set up the
+    reader to use it in the manner described above.
+
+    It is useful to examine some of the functions inherited by
+    QXmlDefaultHandler, and consider why they might be
+    reimplemented in a custom handler.
+    Custom handlers will typically reimplement
+    QXmlContentHandler::startDocument() to prepare the handler for
+    new content. Document elements and the text within them can be
+    processed by reimplementing QXmlContentHandler::startElement(),
+    QXmlContentHandler::endElement(), and
+    QXmlContentHandler::characters().
+    You may want to reimplement QXmlContentHandler::endDocument()
+    to perform some finalization or validation on the content once the
+    document has been read completely.

+    \class QXmlReader
+    \reentrant
+    \brief The QXmlReader class provides an interface for XML readers (i.e.
+    parsers).
+
+    \inmodule QtXml
+    \ingroup xml-tools
+
+    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 \link
+    http://www.saxproject.org/ SAX2 Java interface\endlink, 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 behavior (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().

+    \class QXmlSimpleReader
+    \nonreentrant
+    \brief The QXmlSimpleReader class provides an implementation of a
+    simple XML parser.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+    \mainclass
+
+    This XML reader is suitable for a wide range of applications. It
+    is able to parse well-formed XML and can report the namespaces of
+    elements to a content handler; however, it does not parse any
+    external entities. For historical reasons, Attribute Value
+    Normalization and End-of-Line Handling as described in the XML 1.0
+    specification is not performed.
+
+    The easiest pattern of use for this class is to create a reader
+    instance, define an input source, specify the handlers to be used
+    by the reader, and parse the data.
+
+    For example, we could use a QFile to supply the input. Here, we
+    create a reader, and define an input source to be used by the
+    reader:
+
+    \snippet doc/src/snippets/xml/simpleparse/main.cpp 0
+
+    A handler lets us perform actions when the reader encounters
+    certain types of content, or if errors in the input are found. The
+    reader must be told which handler to use for each type of
+    event. For many common applications, we can create a custom
+    handler by subclassing QXmlDefaultHandler, and use this to handle
+    both error and content events:
+
+    \snippet doc/src/snippets/xml/simpleparse/main.cpp 1
+
+    If you don't set at least the content and error handlers, the
+    parser will fall back on its default behavior---and will do
+    nothing.
+
+    The most convenient way to handle the input is to read it in a
+    single pass using the parse() function with an argument that
+    specifies the input source:
+
+    \snippet doc/src/snippets/xml/simpleparse/main.cpp 2
+
+    If you can't parse the entire input in one go (for example, it is
+    huge, or is being delivered over a network connection), data can
+    be fed to the parser in pieces. This is achieved by telling
+    parse() to work incrementally, and making subsequent calls to the
+    parseContinue() function, until all the data has been processed.
+
+    A common way to perform incremental parsing is to connect the
+    \c readyRead() signal of the input source to a slot, and handle the
+    incoming data there. For example, the following code shows how a
+    parser for \l{http://web.resource.org/rss/1.0/}{RSS feeds} can be
+    used to incrementally parse data that it receives from a QHttp
+    object:
+
+    \snippet doc/src/snippets/xml/rsslisting/rsslisting.cpp 1
+
+    Aspects of the parsing behavior can be adapted using setFeature()
+    and setProperty(). For example, the following code could be used
+    to enable reporting of namespace prefixes to the content handler:
+
+    QXmlSimpleReader is not reentrant. If you want to use the class
+    in threaded code, lock the code using QXmlSimpleReader with a
+    locking mechanism, such as a QMutex.

+/*!
+    Continues incremental parsing, taking input from the
+    QXmlInputSource that was specified with the most recent
+    call to parse(). To use this function, you \e must have called
+    parse() with the incremental argument set to true.
+
+    Returns false if a parsing error occurs; otherwise returns true,
+    even if the end of the XML file has not been reached. You can
+    continue parsing at a later stage by calling this function again
+    when there is more data available to parse.
+
+    Calling this function when there is no data available in the input
+    source indicates to the reader that the end of the XML file has
+    been reached. If the input supplied up to this point was
+    not well-formed then a parsing error occurs, and false is returned.
+    If the input supplied was well-formed, true is returned.
+    It is important to end the input in this way because it allows you
+    to reuse the reader to parse other XML files.
+
+    Calling this function after the end of file has been reached, but
+    without available data will cause false to be returned whether the
+    previous input was well-formed or not.

+
+  Explanation:
+  ad 1: constants for the states (used in the transition table)
+  ad 2: constants for the input (used in the transition table)
+  ad 3: the transition table for the state machine
+  ad 4: test if we are in a parseContinue() step
+        a) if no, do inititalizations
+        b) if yes, restore the state and call parse functions recursively
+  ad 5: Do some actions according to the state; from the logical execution
+        order, this code belongs after 8 (see there for an explanation)
+  ad 6: Check the character that is at the actual "cursor" position:
+        a) If we reached the EOF, report either error or push the state (in the
+           case of incremental parsing).
+        b) Otherwise, set the input character constant for the transition
+           table.
+  ad 7: Get the new state according to the input that was read.
+  ad 8: Do some actions according to the state. The last line in every case
+        statement reads new data (i.e. it move the cursor). This can also be
+        done by calling another parse...() function. If you need processing for
+        this state after that, you have to put it into the switch statement 5.
+        This ensures that you have a well defined re-entry point, when you ran
+        out of data.
