Conceptually, it is the root of the document tree, and provides the primary access to the document's data..PPSince 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 ownerDocument() function which associates them with the document within whose context they were created..PPThe parsed XML is represented internally by a tree of objects that can be accessed using the various QDom classes. All QDom classes do only reference objects in the internal tree. The internal objects in the DOM tree will get deleted, once the last QDom object referencing them and the QDomDocument are deleted..PPCreation of elements, text nodes, etc. is done via the various factory functions provided in this class. Using the default constructors of the QDom classes will only result in empty objects, that can not be manipulated or inserted into the Document..PPThe QDom classes are typically used as follows:.PP.nf.br  QDomDocument doc( "mydocument" );.br  QFile f( "mydocument.xml" );.br  doc.setContent( f );.br.br  // print out the element names of all elements that are a direct child.br  // of the outermost element..br  QDomElement *docElem = doc.documentElement();.br.br  QDomNode n = docElem.firstChild();.br  while( !n.isNull() ) {.br      QDomElement e = n.toElement(); // try to convert the node to an element..br      if( !e.isNull() ) { // the node was really an element..br          cout << n.name() << endl;.br      }.br      n = n.nextSibling();.br  }.br.br  // lets append a new element to the end of the document.br  QDomElement elem = doc.createElement( "img" );.br  elem.setAttribute( "src", "myimage.png" );.br.br  doc.append( elem );.fi.PPOnce \fCdoc\fR and \fCelem\fR go out of scode, the whole internal tree representing the XML document will get deleted..PPFor further information about the Document Objct Model see http://www.w3.org/TR/REC-DOM-Level-1/.SH MEMBER FUNCTION DOCUMENTATION.SH "QDomDocument::QDomDocument ()"Constructs an empty document..SH "QDomDocument::QDomDocument ( const QString & name )"Creates a document with the name \fIname.\fR.SH "QDomDocument::QDomDocument ( const QDomDocument & x )"Copy constructor..SH "QDomDocument::~QDomDocument ()"Destructor..SH "QDomAttr QDomDocument::createAttribute ( const QString & name )"Creates a new attribute that can be inserted into an element..SH "QDomCDATASection QDomDocument::createCDATASection ( const QString & value )"Creates a new CDATA section that can be inserted into the document..SH "QDomComment QDomDocument::createComment ( const QString & value )"Creates a new comment that can be inserted into the Document..SH "QDomDocumentFragment QDomDocument::createDocumentFragment ()"Creates a new document fragment, that can be used to hold parts of the document, when doing complex manipulations of the document tree..SH "QDomElement QDomDocument::createElement ( const QString & tagName )"Creates a new element with the name \fItagName\fR that can be inserted into the DOM tree..SH "QDomEntityReference QDomDocument::createEntityReference ( const QString & name )"Creates a new entity reference..SH "QDomProcessingInstruction QDomDocument::createProcessingInstruction ( const QString & target, const QString & data )"Creates a new processing instruction that can be inserted into the document..SH "QDomText QDomDocument::createTextNode ( const QString & value )"Creates a text node that can be inserted into the document tree..SH "QDomDocumentType QDomDocument::doctype () const"Returns the document type of this document..SH "QDomElement QDomDocument::documentElement () const"Returns the root element of the document..SH "QDomNodeList QDomDocument::elementsByTagName ( const QString & tagname ) const"Returns a QDomNodeList, that contains all elements in the document with the tag name \fItagname.\fR.SH "QDomImplementation QDomDocument::implementation () const"Returns a QDomImplementation object..SH "bool QDomDocument::isDocument () const \fC[virtual]\fR"Returns TRUE..PPReimplemented from QDomNode..SH "QDomNode::NodeType QDomDocument::nodeType() const \fC[virtual]\fR"Returns \fCDocumentNode.\fR.PPReimplemented from QDomNode..SH "QDomDocument& QDomDocument::operator= ( const QDomDocument & x )"Assignment operator..SH "bool QDomDocument::setContent ( const QString & text )"This function parses the string \fItext\fR and sets it as the content of the document..SH "bool QDomDocument::setContent ( QIODevice * dev )"This is an overloaded member function, provided for convenience.
