public String getNamespaceURI(String prefix)

Get Namespace URI bound to a prefix in the current scope.
When requesting a Namespace URI by prefix, the following table describes the returned Namespace URI value for all possible prefix values:
getNamespaceURI(prefix)
return value for specified prefixes

prefix parameter | Namespace URI return value |
DEFAULT_NS_PREFIX ("") |
default Namespace URI in the current scope or
when there is no default Namespace URI in the current scope |

public String getPrefix(String namespaceURI)
AbstractNamespaceContext
Get prefix bound to Namespace URI in the current scope.
To get all prefixes bound to a Namespace URI in the current
scope, use AbstractNamespaceContext.getPrefixes(String namespaceURI)
.
When requesting a prefix by Namespace URI, the following table describes the returned prefix value for all Namespace URI values:
