Get all prefixes bound to a Namespace URI in the current scope.

An Iterator over String elements is returned in an arbitrary, implementation dependent, order.

The Iterator is not modifiable. e.g. the remove() method will throw UnsupportedOperationException.

When requesting prefixes by Namespace URI, the following table describes the returned prefixes value for all Namespace URI values:

`getPrefixes(namespaceURI)` return value for specified Namespace URIs
Namespace URI parameter	prefixes value returned
bound Namespace URI, including the <default Namespace URI>	`Iterator` over prefixes bound to Namespace URI in the current scope in an arbitrary, implementation dependent, order
unbound Namespace URI	empty `Iterator`
`XMLConstants.XML_NS_URI` ("http://www.w3.org/XML/1998/namespace")	`Iterator` with one element set to `XMLConstants.XML_NS_PREFIX` ("xml")
`XMLConstants.XMLNS_ATTRIBUTE_NS_URI` ("http://www.w3.org/2000/xmlns/")	`Iterator` with one element set to `XMLConstants.XMLNS_ATTRIBUTE` ("xmlns")
`null`	`IllegalArgumentException` is thrown

Parameters:

namespaceURI URI of Namespace to lookup

Returns: Iterator for all prefixes bound to the Namespace URI in the current scope

Exceptions:

IllegalArgumentException When namespaceURI is null
