This class recognizes the encoding of the data by reading the encoding declaration in the XML file if it finds one, and reading the data using the corresponding encoding. If it does not find an encoding declaration, then it assumes that the data is either in 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 data from that device. Or you can set the data explicitly with one of the setData() functions. Usually you either construct a QXmlInputSource that works on a QIODevice* or you construct an empty QXmlInputSource and set the data with setData(). There are only rare occasions where you would want to mix both methods. The QXmlReader subclasses use the next() function to read the input character by character. If you want to start from the beginning again, use reset(). The functions data() and fetchData() are useful if you want to do something with the data other than parsing, e.g. displaying the raw XML file. The benefit of using the QXmlInputClass in such cases is that it tries to use the correct encoding. \sa QXmlReader QXmlSimpleReader */ // the following two are guaranteed not to be a character const ushort QXmlInputSource::EndOfData = 0xfffe; const ushort QXmlInputSource::EndOfDocument = 0xffff; /* Common part of the constructors. */ void QXmlInputSource::init() { d = new QXmlInputSourcePrivate; QT_TRY { d->inputDevice = 0; d->inputStream = 0; setData(QString()); #ifndef QT_NO_TEXTCODEC d->encMapper = 0; #endif d->nextReturnedEndOfData = true; // first call to next() will call fetchData() d->encodingDeclBytes.clear(); d->encodingDeclChars.clear(); d->lookingForEncodingDecl = true; } QT_CATCH(...) { delete(d); QT_RETHROW; } } /*!

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().

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 a \l{QNetworkReply} {network reply} a slot, and handle the incoming data there. See QNetworkAccessManager. Aspects of the parsing behavior can be adapted using setFeature() and setProperty(). 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. \snippet doc/src/snippets/code/src_xml_sax_qxml.cpp 0 */ static inline bool is_S(QChar ch) { ushort uc = ch.unicode(); return (uc == ' ' || uc == '\t' || uc == '\n' || uc == '\r'); } enum NameChar { NameBeginning, NameNotBeginning, NotName }; static const char Begi = (char)NameBeginning; static const char NtBg = (char)NameNotBeginning; static const char NotN = (char)NotName; static const char nameCharTable[128] = { // 0x00 NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, // 0x10 NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, NotN, // 0x20 (0x2D is '-', 0x2E is '.')
