DESCRIPTION
The QDomAttr class represents one attribute of a QDomElement.
For example, the following piece of XML produces an element with no
children, but two attributes:
<link href="http://www.trolltech.com" color="red" />
You can access the attributes of an element with code like this:
QDomElement e = //...
//...
QDomAttr a = e.attributeNode( "href" );
cout << a.value() << endl; // prints "http://www.trolltech.com"
a.setValue( "http://doc.trolltech.com" ); // change the node's attribute
QDomAttr a2 = e.attributeNode( "href" );
cout << a2.value() << endl; // prints "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 must use cloneNode() to
get an independent copy of the attribute.
QDomAttr can return the name() and value() of an attribute. An
attribute's value is set with setValue(). If specified() returns TRUE
the value was either set in the document or set with setValue();
otherwise the value hasn't been set. The node this attribute is
attached to (if any) is returned by ownerElement().

http://www.w3.org/TR/REC-DOM-Level-1/ and http://www.w3.org/TR/DOM-
Level-2-Core/. For a more general introduction of the DOM
implementation see the QDomDocument documentation.

MEMBER FUNCTION DOCUMENTATIONQDomAttr::QDomAttr ()
Constructs an empty attribute.
QDomAttr::QDomAttr ( const QDomAttr & x )
Constructs a copy of x.
The data of the copy is shared (shallow copy): modifying one node will
also change the other. If you want to make a deep copy, use
cloneNode().
QDomAttr::~QDomAttr ()
Destroys the object and frees its resources.
bool QDomAttr::isAttr () const [virtual]
Returns TRUE.
Reimplemented from QDomNode.
QString QDomAttr::name () const [virtual]
Returns the attribute's name.
QDomNode::NodeType QDomAttr::nodeType () const [virtual]
Returns AttributeNode.
Reimplemented from QDomNode.
QDomAttr & QDomAttr::operator= ( const QDomAttr & x )
Assigns x to this DOM attribute.
The data of the copy is shared (shallow copy): modifying one node will
also change the other. If you want to make a deep copy, use
cloneNode().
QDomElement QDomAttr::ownerElement () const [virtual]
Returns the element node this attribute is attached to or a null node
if this attribute is not attached to any element.
void QDomAttr::setValue ( const QString & v ) [virtual]
Sets the attribute's value to v.
See also value().
bool QDomAttr::specified () const [virtual]
Returns TRUE if the attribute has either been expicitly specified in
the XML document or was set by the user with setValue(). Returns FALSE
if the value hasn't been specified or set.
See also setValue().
QString QDomAttr::value () const [virtual]
Returns the value of the attribute or QString::null if the attribute
has not been specified.
See also specified() and setValue().
