DESCRIPTION
The QDomAttr class represents one attribute of a QDomElement

For example, the following piece of XML gives an element with no children, but two attributes:

  <link href="http://www.trolltech.com" color="red" />

One can use the attributes of an element with code similar to:

  QDomElement e = ....;
  QDomAttr a = e.attributeNode( "href" );
  cout << a.value() << endl // gives "http://www.trolltech.com"
  a.setValue( "http://doc.trolltech.com" );
  QDomAttr a2 = e.attributeNode( "href" );
  cout << a2.value() << endl // gives "http://doc.trolltech.com"

This example also shows that changing an attribute received from an element changes the attribute of the element. If you do not want to change the value of the element's attribute you have to use cloneNode() to get an independent copy of the attribute.

For further information about the Document Objct Model see http://www.w3.org/TR/REC-DOM-Level-1/. For a more general introduction of the DOM implementation see the QDomDocument documentation.

MEMBER FUNCTION DOCUMENTATION

QDomAttr::QDomAttr ()
Constructs an empty attribute.

QDomAttr::QDomAttr ( const QDomAttr & x )
Copy constructor.

The data of the copy is shared: modifying one will also change the other. If you want to make a real copy, use cloneNode() instead.

QDomAttr::~QDomAttr ()
Destructor.

bool QDomAttr::isAttr () const [virtual]
Returns TRUE.

Reimplemented from QDomNode.

QString QDomAttr::name () const [virtual]
Returns the name of the attribute.

QDomNode::NodeType QDomAttr::nodeType() const [virtual]
Returns AttributeNode.

Reimplemented from QDomNode.

QDomAttr& QDomAttr::operator= ( const QDomAttr & x )
Assignment operator.

The data of the copy is shared: modifying one will also change the other. If you want to make a real copy, use cloneNode() instead.

void QDomAttr::setValue ( const QString & v ) [virtual]
Sets the value of the attribute to v.

See also value().

bool QDomAttr::specified () const [virtual]
Returns TRUE if the attribute has been expicitly specified in the XML document or was set by the user with setValue(), otherwise FALSE.

See also setValue().

QString QDomAttr::value () const [virtual]
Returns the current value of the attribute. Returns a null string when the attribute has not been specified.

See also specified() and setValue().
