public class QDomAttr
extends QDomNode

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.

Constructor Detail

QDomAttr

public QDomAttr(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

public QDomAttr()

Constructs an empty attribute.

Method Detail

name

public final java.lang.String name()

Returns the attribute's name.


ownerElement

public final QDomElement ownerElement()

Returns the element node this attribute is attached to or a null node if this attribute is not attached to any element.


setValue

public final void setValue(java.lang.String arg__1)

Sets the attribute's value to arg__1.

See Also:
value

specified

public final boolean specified()

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

value

public final java.lang.String value()

Returns the value of the attribute or an empty string if the attribute has not been specified.

See Also:
specified, setValue

fromNativePointer

public static QDomAttr fromNativePointer(QNativePointer nativePointer)
This function returns the QDomAttr instance pointed to by nativePointer

Parameters:
nativePointer - the QNativePointer of which object should be returned.

nativePointerArray

public static QNativePointer nativePointerArray(QDomAttr[] array)
This function returns a QNativePointer that is pointing to the specified QDomAttr array.

Parameters:
array - the array that the returned pointer will point to.
Returns:
a QNativePointer that is pointing to the specified array.
