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="ntqfile.html">TQFile</a> file( "mydocument.xml" ); if ( !file.<a href="ntqfile.html#open">open</a>( <a href="ntqfile.html#open">IO_ReadOnly</a> ) ) return; if ( !doc.<a href="#setContent">setContent</a>( &file ) ) { file.<a href="ntqfile.html#close">close</a>(); return; } file.<a href="ntqfile.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="ntqstring.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>.

If you want to make a <a href="shclass.html#deep-copy">deep copy</a>, use <a href="qdomnode.html#cloneNode">cloneNode</a>(). <h3 class=fn>bool <a name="setContent"></a>TQDomDocument::setContent ( const <a href="qbytearray.html">TQByteArray</a> & buffer, bool namespaceProcessing, <a href="ntqstring.html">TQString</a> * errorMsg = 0, int * errorLine = 0, int * errorColumn = 0 ) </h3> This function parses the XML document from the byte array <em>buffer</em> and sets it as the content of the document. It tries to detect the encoding of the document as required by the XML specification. <p> If <em>namespaceProcessing</em> is TRUE, the parser recognizes namespaces in the XML file and sets the prefix name, local name and namespace URI to appropriate values. If <em>namespaceProcessing</em> is FALSE, the parser does no namespace processing when it reads the XML file. <p> If a parse error occurs, the function returns FALSE; otherwise it returns TRUE. If a parse error occurs and <em>errorMsg</em>, <em>errorLine</em> and <em>errorColumn</em> are not 0, the error message is placed in <em>*errorMsg</em>, the line number <em>*errorLine</em> and the column number in <em>*errorColumn</em>. <p> If <em>namespaceProcessing</em> is TRUE, the function <a href="qdomnode.html#prefix">TQDomNode::prefix</a>() returns a string for all elements and attributes.
