Description</h2> + + + +The TQDomDocument class represents an XML document. + +<p> + +<p> The TQDomDocument class represents the entire XML document. +Conceptually, it is the root of the document tree, and provides +the primary access to the document's data. +<p> Since elements, text nodes, comments, processing instructions, +etc., cannot exist outside the context of a document, the document +class also contains the factory functions needed to create these +objects. The node objects created have an <a href="qdomnode.html#ownerDocument">ownerDocument</a>() function +which associates them with the document within whose context they +were created. The DOM classes that will be used most often are +<a href="qdomnode.html">TQDomNode</a>, TQDomDocument, <a href="qdomelement.html">TQDomElement</a> and <a href="qdomtext.html">TQDomText</a>. +<p> The parsed XML is represented internally by a tree of objects that +can be accessed using the various TQDom classes. All TQDom classes +only <em>reference</em> objects in the internal tree. The internal +objects in the DOM tree will get deleted once the last TQDom +object referencing them and the TQDomDocument itself are deleted. +<p> Creation of elements, text nodes, etc. is done using the various +factory functions provided in this class. Using the default +constructors of the TQDom classes will only result in empty +objects that cannot be manipulated or inserted into the Document. +<p> The TQDomDocument class has several functions for creating document +data, for example, <a href="#createElement">createElement</a>(), <a href="#createTextNode">createTextNode</a>(), +<a href="#createComment">createComment</a>(), <a href="#createCDATASection">createCDATASection</a>(), +<a href="#createProcessingInstruction">createProcessingInstruction</a>(), <a href="#createAttribute">createAttribute</a>() and +<a href="#createEntityReference">createEntityReference</a>(). Some of these functions have versions +that support namespaces, i.e. <a href="#createElementNS">createElementNS</a>() and +<a href="#createAttributeNS">createAttributeNS</a>(). The <a href="#createDocumentFragment">createDocumentFragment</a>() function is used +to hold parts of the document; this is useful for manipulating for +complex documents. +<p> The entire content of the document is set with <a href="#setContent">setContent</a>(). This +function parses the string it is passed as an XML document and +creates the DOM tree that represents the document. The root +element is available using <a href="#documentElement">documentElement</a>(). The textual +representation of the document can be obtained using <a href="#toString">toString</a>(). +<p> It is possible to insert a node from another document into the +document using <a href="#importNode">importNode</a>(). +<p> You can obtain a list of all the elements that have a particular +tag with <a href="#elementsByTagName">elementsByTagName</a>() or with <a href="#elementsByTagNameNS">elementsByTagNameNS</a>(). +<p> The TQDom classes are typically used as follows: +<pre> + TQDomDocument doc( "mydocument" ); + <a href="qfile.html">TQFile</a> file( "mydocument.xml" ); + if ( !file.<a href="qfile.html#open">open</a>( <a href="qfile.html#open">IO_ReadOnly</a> ) ) + return; + if ( !doc.<a href="#setContent">setContent</a>( &file ) ) { + file.<a href="qfile.html#close">close</a>(); + return; + } + file.<a href="qfile.html#close">close</a>(); + + // print out the element names of all elements that are direct children + // of the outermost element. + <a href="qdomelement.html">TQDomElement</a> docElem = doc.<a href="#documentElement">documentElement</a>(); + + <a href="qdomnode.html">TQDomNode</a> n = docElem.<a href="qdomnode.html#firstChild">firstChild</a>(); + while( !n.<a href="qdomnode.html#isNull">isNull</a>() ) { + <a href="qdomelement.html">TQDomElement</a> e = n.<a href="qdomnode.html#toElement">toElement</a>(); // try to convert the node to an element. + if( !e.<a href="qdomnode.html#isNull">isNull</a>() ) { + cout << e.<a href="qdomelement.html#tagName">tagName</a>() << endl; // the node really is an element. + } + n = n.<a href="qdomnode.html#nextSibling">nextSibling</a>(); + } + + // Here we append a new element to the end of the document + <a href="qdomelement.html">TQDomElement</a> elem = doc.<a href="#createElement">createElement</a>( "img" ); + elem.<a href="qdomelement.html#setAttribute">setAttribute</a>( "src", "myimage.png" ); + docElem.<a href="qdomnode.html#appendChild">appendChild</a>( elem ); + </pre> + +<p> Once <tt>doc</tt> and <tt>elem</tt> go out of scope, the whole internal tree +representing the XML document is deleted. +<p> To create a document using DOM use code like this: +<pre> + TQDomDocument doc( "MyML" ); + <a href="qdomelement.html">TQDomElement</a> root = doc.<a href="#createElement">createElement</a>( "MyML" ); + doc.<a href="qdomnode.html#appendChild">appendChild</a>( root ); + + <a href="qdomelement.html">TQDomElement</a> tag = doc.<a href="#createElement">createElement</a>( "Greeting" ); + root.<a href="qdomnode.html#appendChild">appendChild</a>( tag ); + + <a href="qdomtext.html">TQDomText</a> t = doc.<a href="#createTextNode">createTextNode</a>( "Hello World" ); + tag.<a href="qdomnode.html#appendChild">appendChild</a>( t ); + + <a href="qstring.html">TQString</a> xml = doc.<a href="#toString">toString</a>(); + </pre> + +<p> For further information about the Document Object Model see +<a href="http://www.w3.org/TR/REC-DOM-Level-1/">http://www.w3.org/TR/REC-DOM-Level-1/</a> and +<a href="http://www.w3.org/TR/DOM-Level-2-Core/">http://www.w3.org/TR/DOM-Level-2-Core/</a>. +For a more general introduction of the DOM implementation see the +TQDomDocument documentation. +<p>See also <a href="xml-tools.html">XML</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQDomDocument"></a>TQDomDocument::TQDomDocument () +</h3> +Constructs an empty document. + +<h3 class=fn>explicit <a name="TQDomDocument-2"></a>TQDomDocument::TQDomDocument ( const <a href="qstring.html">TQString</a> & name ) +</h3> +Creates a document and sets the name of the document type to <em>name</em>. + +<h3 class=fn>explicit <a name="TQDomDocument-3"></a>TQDomDocument::TQDomDocument ( const <a href="qdomdocumenttype.html">TQDomDocumentType</a> & doctype ) +</h3> +Creates a document with the document type <em>doctype</em>. +<p> <p>See also <a href="qdomimplementation.html#createDocumentType">TQDomImplementation::createDocumentType</a>(). + +<h3 class=fn><a name="TQDomDocument-4"></a>TQDomDocument::TQDomDocument ( const <a href="qdomdocument.html">TQDomDocument</a> & x ) +</h3> +Constructs a copy of <em>x</em>. +<p> The data of the copy is shared (shallow copy): modifying one node +will also change the other.
