Name
Element
Synopsis
This interface represents an element (or tag)
in an XML document. getTagName( ) returns the
tagname of the element, including the namespace prefix if there is
one. When working with namespaces, you will probably prefer to use
the namespace-aware methods defined by the Node
interface. Use getNamespaceURI( ) to get the
namespace URI of the element, and use getLocalName(
) to the local name of the element within that namespace.
You can also use getPrefix( ) to query the
namespace prefix, or setPrefix( ) to change the
namespace prefix (this does not change the namespace URI).
Element defines a getElementsByTagName(
) method and a corresponding namespace-aware
getElementsByTagNameNS( ) method, which behave
just like the methods of the same names on the
Document object, except that they search for named
elements only within the subtree rooted at this
Element.
The remaining methods of the Element interface are
for querying and setting attribute values, testing the existence of
an attribute, and removing an attribute from the
Element. There are a confusing number of methods
to perform these four basic attribute operations. If an
attribute-related method has “NS”
in its name, then it is namespace-aware. If it has
“Node” in its name, then it works
with Attr objects rather than with the simpler string representation of the attribute value. Attributes in XML documents may contain entity references. If your document may include entity references in attribute values, then you ...
