DESCRIPTION

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().

bool QDomAttr::isAttr () const [virtual]

Reimplemented from QDomNode.  

QString QDomAttr::name () const [virtual]

Reimplemented from QDomNode.  

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