getNamespaceURI
Description copied from interface:javax.xml.namespace.NamespaceContext
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 prefixesprefix parameter Namespace URI return value DEFAULT_NS_PREFIX
("")default Namespace URI in the current scope or null
when there is no default Namespace URI in the current scopebound prefix Namespace URI bound to prefix in current scope unbound prefix null

getPrefix
Description copied from interface:javax.xml.namespace.NamespaceContext
Get prefix bound to Namespace URI in the current scope.To get all prefixes bound to a Namespace URI in the current scope, use
NamespaceContext.getPrefixes(String namespaceURI)
.When requesting a prefix by Namespace URI, the following table describes the returned prefix value for all Namespace URI values:

getPrefixes
Description copied from interface:javax.xml.namespace.NamespaceContext
Get all prefixes bound to a Namespace URI in the current scope.The returned
