The node objects created have an ownerDocument() function + which associates them with the document within whose context they + were created. The DOM classes that will be used most often are + TQDomNode, TQDomDocument, TQDomElement and TQDomText. + + The parsed XML is represented internally by a tree of objects that + can be accessed using the various TQDom classes. All TQDom classes + only \e reference 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. + + 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. + + The TQDomDocument class has several functions for creating document + data, for example, createElement(), createTextNode(), + createComment(), createCDATASection(), + createProcessingInstruction(), createAttribute() and + createEntityReference(). Some of these functions have versions + that support namespaces, i.e. createElementNS() and + createAttributeNS(). The createDocumentFragment() function is used + to hold parts of the document; this is useful for manipulating for + complex documents. + + The entire content of the document is set with setContent(). 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 documentElement(). The textual + representation of the document can be obtained using toString(). + + It is possible to insert a node from another document into the + document using importNode(). + + You can obtain a list of all the elements that have a particular + tag with elementsByTagName() or with elementsByTagNameNS(). + + The TQDom classes are typically used as follows: + \code + TQDomDocument doc( "mydocument" ); + TQFile file( "mydocument.xml" ); + if ( !file.open( IO_ReadOnly ) ) + return; + if ( !doc.setContent( &file ) ) { + file.close(); + return; + } + file.close(); + + // print out the element names of all elements that are direct tqchildren + // of the outermost element. + TQDomElement docElem = doc.documentElement(); + + TQDomNode n = docElem.firstChild(); + while( !n.isNull() ) { + TQDomElement e = n.toElement(); // try to convert the node to an element. + if( !e.isNull() ) { + cout << e.tagName() << endl; // the node really is an element. + } + n = n.nextSibling(); + } + + // Here we append a new element to the end of the document + TQDomElement elem = doc.createElement( "img" ); + elem.setAttribute( "src", "myimage.png" ); + docElem.appendChild( elem ); + \endcode + + Once \c doc and \c elem go out of scope, the whole internal tree + representing the XML document is deleted. + + To create a document using DOM use code like this: + \code + TQDomDocument doc( "MyML" ); + TQDomElement root = doc.createElement( "MyML" ); + doc.appendChild( root ); + + TQDomElement tag = doc.createElement( "Greeting" ); + root.appendChild( tag ); + + TQDomText t = doc.createTextNode( "Hello World" ); + tag.appendChild( t ); + + TQString xml = doc.toString(); + \endcode + + For further information about the Document Object Model see + \link http://www.w3.org/TR/REC-DOM-Level-1/\endlink and + \link http://www.w3.org/TR/DOM-Level-2-Core/\endlink. + For a more general introduction of the DOM implementation see the + TQDomDocument documentation. +*/ + + +/*! + Constructs an empty document. +*/ +TQDomDocument::TQDomDocument() +{ + impl = 0; +} + +/*! + Creates a document and sets the name of the document type to \a + name. +*/ +TQDomDocument::TQDomDocument( const TQString& name ) +{ + // We take over ownership + impl = new TQDomDocumentPrivate( name ); +} + +/*! + Creates a document with the document type \a doctype. + + \sa TQDomImplementation::createDocumentType() +*/ +TQDomDocument::TQDomDocument( const TQDomDocumentType& doctype ) +{ + impl = new TQDomDocumentPrivate( (TQDomDocumentTypePrivate*)(doctype.impl) ); +} + +/*! + Constructs a copy of \a x. + + The data of the copy is shared (shallow copy): modifying one node + will also change the other.
