Implements

This method finds the mapped prefix by walking the stack (that is, it looks globally). The supplied string must be atomized for the lookup to succeed. In other words, the supplied string object must exist in the XmlNamespaceManager's NameTable.

The returned string is also atomized. For more information on atomized strings, see XmlNameTable.

The following example removes a namespace from the namespace manager.

Dim prefix As String = nsmgr.LookupPrefix("www.wideworldimporters.com/europe")
nsmgr.RemoveNamespace(prefix, "www.wideworldimporters.com/europe")

String prefix = nsmgr.LookupPrefix("www.wideworldimporters.com/europe");
nsmgr.RemoveNamespace(prefix, "www.wideworldimporters.com/europe");

String^ prefix = nsmgr->LookupPrefix( "www.wideworldimporters.com/europe" );
nsmgr->RemoveNamespace( prefix, "www.wideworldimporters.com/europe" );

String* prefix = nsmgr->LookupPrefix(S"www.wideworldimporters.com/europe");
nsmgr->RemoveNamespace(prefix, S"www.wideworldimporters.com/europe");
