Detailed 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(). +

For further information about the Document Object Model see +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 Documentation

+

QDomAttr::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(). + + +
