Method Detail

getNamespaceURI

public java.lang.String getNamespaceURI(java.lang.String prefix)
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 prefixes
prefix 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 scope
bound prefix Namespace URI bound to prefix in current scope
unbound prefix null
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

Specified by:
getNamespaceURI in interface javax.xml.namespace.NamespaceContext
Parameters:
prefix - prefix to look up
Returns:
Namespace URI bound to prefix in the current scope

getPrefix

public java.lang.String getPrefix(java.lang.String uri)
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:

getPrefix(namespaceURI) 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")
"" or null IllegalArgumentException is thrown

Specified by:
getPrefix in interface javax.xml.namespace.NamespaceContext
Parameters:
uri - URI of Namespace to lookup
Returns:
prefix bound to Namespace URI in current context

getDefaultNameSpace

public java.lang.String getDefaultNameSpace()

getPrefixes

public java.util.Iterator getPrefixes(java.lang.String uri)
Description copied from interface: javax.xml.namespace.NamespaceContext
Get all prefixes bound to a Namespace URI in the current scope.

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

Prefixes are returned in an arbitrary, implementation dependent, order.

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")
"" or null IllegalArgumentException is thrown

Specified by:
getPrefixes in interface javax.xml.namespace.NamespaceContext
Parameters:
uri - URI of Namespace to lookup
Returns:
Iterator for all prefixes bound to the Namespace URI in the current scope

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception
Throws:
java.lang.Exception
