Detailed Description#


This section contains snippets that were automatically translated from C++ to Python and may contain errors.

For example, the following piece of XML produces an element with no children, but two attributes:

<link href="" color="red" />

You can access the attributes of an element with code like this:

e = QDomElement()
a = e.attributeNode("href")
print(qPrintable(a.value()), '\n' # prints "")
a.setValue(""); // change the node's attribute
a2 = e.attributeNode("href")
print(qPrintable(a2.value()), '\n' # prints "")

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 set with setValue() . The node this attribute is attached to (if any) is returned by ownerElement() .

For further information about the Document Object Model see and . For a more general introduction of the DOM implementation see the QDomDocument documentation.


Constructs an empty attribute.



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() .

Return type:

Return type:


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