OpenJDK 27 · com.sun.org.apache.xml.internal.security.utils.DOMNamespaceContext

This class adapts the Node namespace/prefix lookup API to that of NamespaceContext. There are some differences:

Function	`NamespaceContext` API	`Node` API
Look up the prefix for a given namespace URI.	`NamespaceContext#getPrefix(String)`	`Node#lookupPrefix(String)`
Look up all the prefixes for a given namespace URI.	`NamespaceContext#getPrefixes(String)`	/
Look up the namespace URI for a given prefix.	`NamespaceContext#getNamespaceURI(String)`	`Node#lookupNamespaceURI(String)`
The default prefix.	`javax.xml.XMLConstants#DEFAULT_NS_PREFIX`	`null`
The default namespace URI.	`javax.xml.XMLConstants#NULL_NS_URI`	`null`

Method Detail

getNamespaceURI back to summary

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:

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

public String getPrefix(String namespaceURI)

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
