Here we present a brief introduction; skip to + \link #namespacesConventions Qt XML documentation conventions \endlink + if you already know this material. + + Namespaces are a concept introduced into XML to allow a more modular + design. With their help data processing software can easily resolve + naming conflicts in XML documents. + + Consider the following example: + + \snippet code/doc_src_qtxml.qdoc 6 + + Here we find three different uses of the name \e title. If you wish to + process this document you will encounter problems because each of the + \e titles should be displayed in a different manner -- even though + they have the same name. + + The solution would be to have some means of identifying the first + occurrence of \e title as the title of a book, i.e. to use the \e + title element of a book namespace to distinguish it from, for example, + the chapter title, e.g.: + \snippet code/doc_src_qtxml.qdoc 7 + + \e book in this case is a \e prefix denoting the namespace. + + Before we can apply a namespace to element or attribute names we must + declare it. + + Namespaces are URIs like \e http://www.example.com/fnord/book/. This + does not mean that data must be available at this address; the URI is + simply used to provide a unique name. + + We declare namespaces in the same way as attributes; strictly speaking + they \e are attributes. To make for example \e + http://www.example.com/fnord/ the document's default XML namespace \e + xmlns we write + + \snippet code/doc_src_qtxml.qdoc 8 + + To distinguish the \e http://www.example.com/fnord/book/ namespace from + the default, we must supply it with a prefix: + + \snippet code/doc_src_qtxml.qdoc 9 + + A namespace that is declared like this can be applied to element and + attribute names by prepending the appropriate prefix and a ":" + delimiter. We have already seen this with the \e book:title element. + + Element names without a prefix belong to the default namespace. This + rule does not apply to attributes: an attribute without a prefix does + not belong to any of the declared XML namespaces at all. Attributes + always belong to the "traditional" namespace of the element in which + they appear. A "traditional" namespace is not an XML namespace, it + simply means that all attribute names belonging to one element must be + different. Later we will see how to assign an XML namespace to an + attribute. + + Due to the fact that attributes without prefixes are not in any XML + namespace there is no collision between the attribute \e title (that + belongs to the \e author element) and for example the \e title element + within a \e chapter. + + Let's clarify this with an example: + \snippet code/doc_src_qtxml.qdoc 10 + + Within the \e document element we have two namespaces declared. The + default namespace \e http://www.example.com/fnord/ applies to the \e + book element, the \e chapter element, the appropriate \e title element + and of course to \e document itself. + + The \e book:author and \e book:title elements belong to the namespace + with the URI \e http://www.example.com/fnord/book/. + + The two \e book:author attributes \e title and \e name have no XML + namespace assigned. They are only members of the "traditional" + namespace of the element \e book:author, meaning that for example two + \e title attributes in \e book:author are forbidden. + + In the above example we circumvent the last rule by adding a \e title + attribute from the \e http://www.example.com/fnord/ namespace to \e + book:author: the \e fnord:title comes from the namespace with the + prefix \e fnord that is declared in the \e book:author element. + + Clearly the \e fnord namespace has the same namespace URI as the + default namespace. So why didn't we simply use the default namespace + we'd already declared? The answer is quite complex: + \list + \li attributes without a prefix don't belong to any XML namespace at + all, not even to the default namespace; + \li additionally omitting the prefix would lead to a \e title-title clash; + \li writing it as \e xmlns:title would declare a new namespace with the + prefix \e title instead of applying the default \e xmlns namespace. + \endlist + + With the Qt XML classes elements and attributes can be accessed in two + ways: either by refering to their qualified names consisting of the + namespace prefix and the "real" name (or \e local name) or by the + combination of local name and namespace URI. + + More information on XML namespaces can be found at + \l http://www.w3.org/TR/REC-xml-names/. + + \target namespacesConventions + \section1 Conventions Used in the Qt XML Documentation + + The following terms are used to distinguish the parts of names within + the context of namespaces: + \list + \li The \e {qualified name} + is the name as it appears in the document. (In the above example \e + book:title is a qualified name.) + \li A \e {namespace prefix} in a qualified name + is the part to the left of the ":". (\e book is the namespace prefix in + \e book:title.) + \li The \e {local part} of a name (also refered to as the \e {local + name}) appears to the right of the ":". (Thus \e title is the + local part of \e book:title.) + \li The \e {namespace URI} ("Uniform Resource Identifier") is a unique + identifier for a namespace. It looks like a URL + (e.g. \e http://www.example.com/fnord/ ) but does not require + data to be accessible by the given protocol at the named address. + \endlist + + Elements without a ":" (like \e chapter in the example) do not have a + namespace prefix. In this case the local part and the qualified name + are identical (i.e. \e chapter). + + \sa {DOM Bookmarks Example}, {SAX Bookmarks Example} +*/ + +/*! + \page xml-streaming.html + \title XML Streaming + + \previouspage An Introduction to Namespaces + \contentspage XML Processing + \nextpage The SAX Interface + + Since version 4.3, Qt provides two new classes for reading and + writing XML: QXmlStreamReader and QXmlStreamWriter. + + The QXmlStreamReader and QXmlStreamWriter are two new classes provided + in Qt 4.3 and later. A stream reader reports an XML document as a stream + of tokens. This differs from SAX as SAX applications provide handlers to + receive XML events from the parser whereas the QXmlStreamReader drives the + loop, pulling tokens from the reader when they are needed. + This pulling approach makes it possible to build recursive descent parsers, + allowing XML parsing code to be split into different methods or classes. + + QXmlStreamReader is a well-formed XML 1.0 parser that excludes external + parsed entities. Hence, data provided by the stream reader adheres to the + W3C's criteria for well-formed XML, as long as no error occurs. Otherwise, + functions such as \l{QXmlStreamReader::atEnd()}{atEnd()}, + \l{QXmlStreamReader::error()}{error()} and \l{QXmlStreamReader::hasError()} + {hasError()} can be used to check and view the errors. + + An example of QXmlStreamReader implementation would be the \c XbelReader in + \l{QXmlStream Bookmarks Example}, which is a subclass of QXmlStreamReader. + The constructor takes \a treeWidget as a parameter and the class has Xbel + specific functions: + + \snippet xml/streambookmarks/xbelreader.h 1 + + \dots + \snippet xml/streambookmarks/xbelreader.h 2 + \dots + + The \c read() function accepts a QIODevice and sets it with + \l{QXmlStreamReader::setDevice()}{setDevice()}. The + \l{QXmlStreamReader::raiseError()}{raiseError()} function is used to + display a custom error message, inidicating that the file's version + is incorrect. + + \snippet xml/streambookmarks/xbelreader.cpp 1 + + The pendent to QXmlStreamReader is QXmlStreamWriter, which provides an XML + writer with a simple streaming API. QXmlStreamWriter operates on a + QIODevice and has specialised functions for all XML tokens or events you + want to write, such as \l{QXmlStreamWriter::writeDTD()}{writeDTD()}, + \l{QXmlStreamWriter::writeCharacters()}{writeCharacters()}, + \l{QXmlStreamWriter::writeComment()}{writeComment()} and so on. + + To write XML document with QXmlStreamWriter, you start a document with the + \l{QXmlStreamWriter::writeStartDocument()}{writeStartDocument()} function + and end it with \l{QXmlStreamWriter::writeEndDocument()} + {writeEndDocument()}, which implicitly closes all remaining open tags. + Element tags are opened with \l{QXmlStreamWriter::writeStartDocument()} + {writeStartDocument()} and followed by + \l{QXmlStreamWriter::writeAttribute()}{writeAttribute()} or + \l{QXmlStreamWriter::writeAttributes()}{writeAttributes()}, + element content, and then \l{QXmlStreamWriter::writeEndDocument()} + {writeEndDocument()}. Also, \l{QXmlStreamWriter::writeEmptyElement()} + {writeEmptyElement()} can be used to write empty elements. + + Element content comprises characters, entity references or nested elements. + Content can be written with \l{QXmlStreamWriter::writeCharacters()} + {writeCharacters()}, a function that also takes care of escaping all + forbidden characters and character sequences, + \l{QXmlStreamWriter::writeEntityReference()}{writeEntityReference()}, + or subsequent calls to \l{QXmlStreamWriter::writeStartElement()} + {writeStartElement()}. + + The \c XbelWriter class from \l{QXmlStream Bookmarks Example} is a subclass + of QXmlStreamWriter. Its \c writeFile() function illustrates the core + functions of QXmlStreamWriter mentioned above: + + \snippet xml/streambookmarks/xbelwriter.cpp 1 +*/ + +/*! + \page xml-sax.html + \title The SAX interface + + \previouspage XML Streaming + \contentspage XML Processing + \nextpage Working with the DOM Tree + + SAX is an event-based standard interface for XML parsers. + The Qt interface follows the design of the SAX2 Java implementation. + Its naming scheme was adapted to fit the Qt naming conventions. + Details on SAX2 can be found at \l{http://www.saxproject.org}. + + Support for SAX2 filters and the reader factory are under + development. The Qt implementation does not include the SAX1 + compatibility classes present in the Java interface. + + \section1 Introduction to SAX2 + + The SAX2 interface is an event-driven mechanism to provide the user with + document information. An "event" in this context means something + reported by the parser, for example, it has encountered a start tag, + or an end tag, etc. + + To make it less abstract consider the following example: + \snippet code/doc_src_qtxml.qdoc 3 + + Whilst reading (a SAX2 parser is usually referred to as "reader") + the above document three events would be triggered: + \list 1 + \li A start tag occurs (\c{<quote>}). + \li Character data (i.e. text) is found, "A quotation.". + \li An end tag is parsed (\c{</quote>}). + \endlist + + Each time such an event occurs the parser reports it; you can set up + event handlers to respond to these events. + + Whilst this is a fast and simple approach to read XML documents, + manipulation is difficult because data is not stored, simply handled + and discarded serially. The \l{Working with the DOM Tree}{DOM interface} + reads in and stores the whole document in a tree structure; + this takes more memory, but makes it easier to manipulate the + document's structure. + + The Qt XML module provides an abstract class, \l QXmlReader, that + defines the interface for potential SAX2 readers. Qt includes a reader + implementation, \l QXmlSimpleReader, that is easy to adapt through + subclassing. + + The reader reports parsing events through special handler classes: + \table + \header \li Handler class \li Description + \row \li \l QXmlContentHandler + \li Reports events related to the content of a document (e.g. the start tag + or characters). + \row \li \l QXmlDTDHandler + \li Reports events related to the DTD (e.g. notation declarations). + \row \li \l QXmlErrorHandler + \li Reports errors or warnings that occurred during parsing. + \row \li \l QXmlEntityResolver + \li Reports external entities during parsing and allows users to resolve + external entities themselves instead of leaving it to the reader. + \row \li \l QXmlDeclHandler + \li Reports further DTD related events (e.g. attribute declarations). + \row \li \l QXmlLexicalHandler + \li Reports events related to the lexical structure of the + document (the beginning of the DTD, comments etc.). + \endtable + + These classes are abstract classes describing the interface. The \l + QXmlDefaultHandler class provides a "do nothing" default + implementation for all of them. Therefore users only need to overload + the QXmlDefaultHandler functions they are interested in. + + To read input XML data a special class \l QXmlInputSource is used. + + Apart from those already mentioned, the following SAX2 support classes + provide additional useful functionality: + \table + \header \li Class \li Description + \row \li \l QXmlAttributes + \li Used to pass attributes in a start element event. + \row \li \l QXmlLocator + \li Used to obtain the actual parsing position of an event. + \row \li \l QXmlNamespaceSupport + \li Used to implement namespace support for a reader. Note that + namespaces do not change the parsing behavior. They are only + reported through the handler. + \endtable + + The \l{SAX Bookmarks example} illustrates how to subclass + QXmlDefaultHandler to read an XML bookmark file (XBEL) and + how to generate XML by hand. + + \section1 SAX2 Features + + The behavior of an XML reader depends on its support for certain + optional features. For example, a reader may have the feature "report + attributes used for namespace declarations and prefixes along with + the local name of a tag". Like every other feature this has a unique + name represented by a URI: it is called + \e http://xml.org/sax/features/namespace-prefixes. + + The Qt SAX2 implementation can report whether the reader has + particular functionality using the QXmlReader::hasFeature() + function. Available features can be tested with QXmlReader::feature(), + and switched on or off using QXmlReader::setFeature(). + + Consider the example + \snippet code/doc_src_qtxml.qdoc 4 + A reader that does not support the \e + http://xml.org/sax/features/namespace-prefixes feature would report + the element name \e document but not its attributes \e xmlns:book and + \e xmlns with their values. A reader with the feature \e + http://xml.org/sax/features/namespace-prefixes reports the namespace + attributes if the \link QXmlReader::feature() feature\endlink is + switched on. + + Other features include \e http://xml.org/sax/features/namespace + (namespace processing, implies \e + http://xml.org/sax/features/namespace-prefixes) and \e + http://xml.org/sax/features/validation (the ability to report + validation errors). + + Whilst SAX2 leaves it to the user to define and implement whatever + features are required, support for \e + http://xml.org/sax/features/namespace (and thus \e + http://xml.org/sax/features/namespace-prefixes) is mandantory. + The \l QXmlSimpleReader implementation of \l QXmlReader, + supports them, and can do namespace processing. + + \l QXmlSimpleReader is not validating, so it + does not support \e http://xml.org/sax/features/validation. + + \section1 Namespace Support via Features + + As we have seen in the previous section, we can configure the + behavior of the reader when it comes to namespace + processing. This is done by setting and unsetting the + \e http://xml.org/sax/features/namespaces and + \e http://xml.org/sax/features/namespace-prefixes features. + + They influence the reporting behavior in the following way: + \list 1 + \li Namespace prefixes and local parts of elements and attributes can + be reported. + \li The qualified names of elements and attributes are reported. + \li \l QXmlContentHandler::startPrefixMapping() and \l + QXmlContentHandler::endPrefixMapping() are called by the reader. + \li Attributes that declare namespaces (i.e. the attribute \e xmlns and + attributes starting with \e{xmlns:}) are reported. + \endlist + + Consider the following element: + \snippet code/doc_src_qtxml.qdoc 5 + With \e http://xml.org/sax/features/namespace-prefixes set to true + the reader will report four attributes; but with the \e + namespace-prefixes feature set to false only three, with the \e + xmlns:fnord attribute defining a namespace being "invisible" to the + reader. + + The \e http://xml.org/sax/features/namespaces feature is responsible + for reporting local names, namespace prefixes and URIs. With \e + http://xml.org/sax/features/namespaces set to true the parser will + report \e title as the local name of the \e fnord:title attribute, \e + fnord being the namespace prefix and \e http://example.com/fnord/ as + the namespace URI. When \e http://xml.org/sax/features/namespaces is + false none of them are reported. + + In the current implementation the Qt XML classes follow the definition + that the prefix \e xmlns itself isn't associated with any namespace at all + (see \l{http://www.w3.org/TR/1999/REC-xml-names-19990114/#ns-using}). + Therefore even with \e http://xml.org/sax/features/namespaces and + \e http://xml.org/sax/features/namespace-prefixes both set to true + the reader won't return either a local name, a namespace prefix or + a namespace URI for \e xmlns:fnord. + + This might be changed in the future following the W3C suggestion + \link http://www.w3.org/2000/xmlns/ http://www.w3.org/2000/xmlns/ \endlink + to associate \e xmlns with the namespace \e http://www.w3.org/2000/xmlns. + + As the SAX2 standard suggests, \l QXmlSimpleReader defaults to having + \e http://xml.org/sax/features/namespaces set to true and + \e http://xml.org/sax/features/namespace-prefixes set to false. + When changing this behavior using \l QXmlSimpleReader::setFeature() + note that the combination of both features set to + false is illegal. + + \section2 Summary + + \l QXmlSimpleReader implements the following behavior: + + \table + \header \li (namespaces, namespace-prefixes) + \li Namespace prefix and local part + \li Qualified names + \li Prefix mapping + \li xmlns attributes + \row \li (true, false) \li Yes \li Yes* \li Yes \li No + \row \li (true, true) \li Yes \li Yes \li Yes \li Yes + \row \li (false, true) \li No* \li Yes \li No* \li Yes + \row \li (false, false) \li {4,1} Illegal + \endtable + + The behavior of the entries marked with an asterisk (*) is not specified by SAX. + + \section1 Properties + + Properties are a more general concept.

This concept involves some + danger, though: there is no means of ensuring type-safety; the user + must take care that they pass the right type. Properties are + useful if a reader supports special handler classes. + + The URIs used for features and properties often look like URLs, e.g. + \c http://xml.org/sax/features/namespace. This does not mean that the + data required is at this address.
