        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

        null IllegalArgumentException is thrown
        Specified by:
        getNamespaceURI in interface NamespaceContext
        Parameters:
        prefix - prefix to look up

      • getPrefix

        public String getPrefix​(String namespaceURI)
        Get prefix bound to Namespace URI in the current scope (the XML file).

        Multiple prefixes bound to Namespace URI will be normalized to the first prefix defined.

        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")
        null IllegalArgumentException is thrown
        Specified by:
        getPrefix in interface NamespaceContext
        Parameters:
        namespaceURI - URI of Namespace to lookup
        Returns:
        prefix bound to Namespace URI in current context
        Throws:
        IllegalArgumentException - When namespaceURI is null

      • getPrefixes

        public Iterator<String> getPrefixes​(String namespaceURI)
        Get all prefixes bound to a Namespace URI in the current scope. (the XML file)

        NOTE: Multiple prefixes bound to a similar Namespace URI will be normalized to the first prefix defined. Still the namespace attributes exist in the XML as inner value prefixes might be used.

        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
        Specified by:
        getPrefixes in interface NamespaceContext
        Parameters:
        namespaceURI - URI of Namespace to lookup
        Returns:
        Iterator for all prefixes bound to the Namespace URI in the current scope
        Throws:
        IllegalArgumentException - When namespaceURI is null

      • setNamespace

        public OdfNamespace setNamespace​(String prefix,
                                 String uri)
        Adds a new Namespace to the DOM. Making the prefix usable with JDK XPath. All namespace attributes will be written to the root element during later serialization of the DOM by the OdfPackage.
        Parameters:
        prefix - of the namespace to be set to this DOM
        uri - of the namespace to be set to this DOM
        Returns:
        the namespace that was set. If an URI was registered before to the DOM, the previous prefix will be taken. In case of a given prefix that was already registered, but related to a new URI, the prefix will be adapted. The new prefix receives the suffix '__' plus integer, e.g. "__1" for the first duplicate and "__2" for the second.

      • setNamespace

        public OdfNamespace setNamespace​(NamespaceName name)
        Adds a new Namespace to the DOM. Making the prefix usable with JDK XPath. All namespace attributes will be written to the root element during later serialization of the DOM by the OdfPackage.
        Parameters:
        name - the namespace to be set
        Returns:
        the namespace that was set. If an URI was registered before to the DOM, the previous prefix will be taken. In case of a given prefix that was already registered, but related to a new URI, the prefix will be adapted. The new prefix receives the suffix '__' plus integer, e.g. "__1" for the first duplicate and "__2" for the second.
