Doc from javax.xml.namespace.NamespaceContext.getNamespaceURI.

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:

Return value for specified prefixes
prefix parameter Namespace URI return value
DEFAULT_NS_PREFIX ("") default Namespace URI in the current scope or XMLConstants.NULL_NS_URI("") when there is no default Namespace URI in the current scope
bound prefix Namespace URI bound to prefix in current scope
unbound prefix XMLConstants.NULL_NS_URI("")
XMLConstants.XML_NS_PREFIX ("xml") XMLConstants.XML_NS_URI ("http://www.w3.org/XML/1998/namespace")
XMLConstants.XMLNS_ATTRIBUTE ("xmlns") XMLConstants.XMLNS_ATTRIBUTE_NS_URI ("http://www.w3.org/2000/xmlns/")
null IllegalArgumentException is thrown
Parameters
prefix:String

prefix to look up

Returns:String

Namespace URI bound to prefix in the current scope

public String getPrefix(String nsURI)

Implements javax.xml.namespace.NamespaceContext.getPrefix.

Doc from javax.xml.namespace.NamespaceContext.getPrefix.

Get prefix bound to Namespace URI in the current scope.

To get all prefixes bound to a Namespace URI in the current scope, use getPrefixes(String namespaceURI).

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

Return value for specified Namespace URIs
Namespace URI parameter prefix value returned
<default Namespace URI> XMLConstants.DEFAULT_NS_PREFIX ("")
bound Namespace URI prefix bound to Namespace URI in the current scope, if multiple prefixes are bound to the Namespace URI in the current scope, a single arbitrary prefix, whose choice is implementation dependent, is returned
unbound Namespace URI null
XMLConstants.XML_NS_URI ("http://www.w3.org/XML/1998/namespace") XMLConstants.XML_NS_PREFIX ("xml")
XMLConstants.XMLNS_ATTRIBUTE_NS_URI ("http://www.w3.org/2000/xmlns/") XMLConstants.XMLNS_ATTRIBUTE ("xmlns")
null IllegalArgumentException is thrown
Parameters
nsURI:String

URI of Namespace to lookup

Returns:String

prefix bound to Namespace URI in current context

public Iterator<String> getPrefixes(String nsURI)

Implements javax.xml.namespace.NamespaceContext.getPrefixes.

Doc from javax.xml.namespace.NamespaceContext.getPrefixes.

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:

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
nsURI:String

URI of Namespace to lookup

Returns:Iterator<String>

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