Class Namespace

• TopLevel.Object
  • TopLevel.Namespace

Namespace objects represent XML namespaces and provide an association between a namespace prefix and a Unique Resource Identifier (URI). The prefix is either the undefined value or a string value that may be used to reference the namespace within the lexical representation of an XML value. When an XML object containing a namespace with an undefined prefix is encoded as XML by the method toXMLString(), the implementation will automatically generate a prefix. The URI is a string value used to uniquely identify the namespace.

Property Summary 

Property	Description
prefix: String (read-only)	Returns the prefix of the Namespace object.
uri: String (read-only)	Returns the Uniform Resource Identifier (URI) of the Namespace object.

Constructor Summary 

Constructor	Description
Namespace()	Constructs a simple namespace where the uri and prefix properties are set to an empty string.
Namespace(Object)	Constructs a Namespace object and assigns values to the uri and prefix properties based on the type of uriValue.
Namespace(Object, Object)	Constructs a Namespace object and assigns values to the uri and prefix properties.

Method Summary 

Method	Description
getPrefix()	Returns the prefix of the Namespace object.
getUri()	Returns the Uniform Resource Identifier (URI) of the Namespace object.
toString()	Returns a string representation of this Namespace object.

Property Details 

prefix 

prefix: String (read-only)

Returns the prefix of the Namespace object.

---

uri 

uri: String (read-only)

Returns the Uniform Resource Identifier (URI) of the Namespace object.

---

Constructor Details 

Namespace() 

Namespace()

Constructs a simple namespace where the uri and prefix properties are set to an empty string. A namespace with URI set to the empty string represents no namespace. No namespace is used in XML objects to explicitly specify that a name is not inside a namespace and may never be associated with a prefix other than the empty string.

---

Namespace(Object) 

Namespace(uriValue: Object)

Constructs a Namespace object and assigns values to the uri and prefix properties based on the type of uriValue. If uriValue is a Namespace object, a copy of the Namespace is constructed. If uriValue is a QName object, the uri property is set to the QName object's uri property. Otherwise, uriValue is converted into a string and assigned to the uri property.

Parameters:

• uriValue - the value to use when constructing the Namespace.

---

Namespace(Object, Object) 

Namespace(prefixValue: Object, uriValue: Object)

Constructs a Namespace object and assigns values to the uri and prefix properties.

The value of the prefixValue parameter is assigned to the prefix property in the following manner:

1. If undefined is passed, prefix is set to undefined.
2. If the argument is a valid XML name, it is converted to a string and assigned to the prefix property.
3. If the argument is not a valid XML name, the prefix property is set to undefined.

The value of the uriValue parameter is assigned to the uri property in the following manner:

1. If a QName object is passed for the uriValue parameter, the uri property is set to the value of the QName object's uri property.
2. If a QName object is not passed for the uriValue parameter, the uriValue parameter is converted to a string and assigned to the uri property.

Parameters:

• prefixValue - the prefix value to use when constructing the Namespace.
• uriValue - the value to use when constructing the Namespace.

Returns:

• the Uniform Resource Identifier (URI) of the Namespace object.

---

toString() 

toString(): String

Returns a string representation of this Namespace object.

Returns:

• a string representation of this Namespace object.
