Type:
System::String^
The prefix whose namespace URI you want to resolve. To match the default namespace, pass String::Empty.
Return Value
Type: System::String^A String that contains the namespace URI assigned to the namespace prefix specified; null if no namespace URI is assigned to the prefix specified. The String returned is atomized.
If String::Empty is specified as the prefix parameter, the currently assigned default namespace URI is returned. If no default namespace URI is explicitly assigned, and String::Empty is specified as the prefix parameter, the blank prefix is associated with elements that are not in any namespace, and String::Empty is returned.
Note |
|---|
The prefix to namespace URI mappings can change from node to node in an XML document. As a result, the value of the LookupNamespace method may not be consistent from one node to the next. |
For an example of the LookupNamespace method, see the InsertElementAfter or InsertElementBefore methods.
