Detailed Description¶
For example, the following piece of XML produces an element with no children, but two attributes:
<link href="http://qt-project.org" color="red" />You can access the attributes of an element with code like this:
e = # some QDomElement... #... a = e.attributeNode("href") print a.value() # prints "http://qt-project.org.com" a.setValue("http://qt-project.org/doc") # change the node's attribute a2 = e.attributeNode("href") print a2.value() # prints "http://qt-project.org/doc"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 thename()
andvalue()
of an attribute. An attribute’s value is set withsetValue()
. Ifspecified()
returns true the value was set withsetValue()
. The node this attribute is attached to (if any) is returned byownerElement()
.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.
