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.

QDomAttr(3qt)QDomAttr(3qt)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().
