Namespace object constructors

The Namespace constructor takes several forms:

new Namespace()

new Namespace (String uri)

new Namespace (QName prefix)

new Namespace (Namespace ns)

new Namespace (String prefix, String uri)

When no argument is supplied, creates a namespace with an empty prefix and URI.

Namespace object properties

uri

String Creates a Namespace object with an empty prefix and the given URI.

prefix

QName Creates a namespace with an empty prefix and the URI set to the URI of the

QName object

(if the QName object contains a URI).

Namespace Creates a copy of the given Namespace object.

If the

Namespace() function is called without the new operator, and the only

argument is a

Namespace object, the function simply returns that object,

rather than creating a copy.

prefix,

uri

String Creates a Namespace object with the given prefix and the given URI.

prefix

String The element-name prefix associated with the namespace URI.

The prefix value can be

undefined, as when a specified prefix is not a valid XML

name. Namespaces with an undefined prefix are completely ignored; they are not

added to an XML namespace declaration.

uri

String The location of the namespace definition, a URI.
