      • getPrefix

        protected static java.lang.String getPrefix​(NodePointer pointer,
                                            java.lang.String namespaceURI)
        Find the namespace prefix for the specified namespace URI and NodePointer.
        Parameters:
        pointer - location
        namespaceURI - to check
        Returns:
        prefix if found
        Since:
        JXPath 1.3

      • registerNamespace

        public void registerNamespace​(java.lang.String prefix,
                              java.lang.String namespaceURI)
        Registers a namespace prefix.
        Parameters:
        prefix - A namespace prefix
        namespaceURI - A URI for that prefix

      • setNamespaceContextPointer

        public void setNamespaceContextPointer​(NodePointer pointer)
        Register a namespace for the expression context.
        Parameters:
        pointer - the Pointer to set.

      • getNamespaceContextPointer

        public Pointer getNamespaceContextPointer()
        Get the namespace context pointer.
        Returns:
        Pointer

      • getNamespaceURI

        public java.lang.String getNamespaceURI​(java.lang.String prefix)
        Given a prefix, returns a registered namespace URI. If the requested prefix was not defined explicitly using the registerNamespace method, JXPathContext will then check the context node to see if the prefix is defined there. See setNamespaceContextPointer.
        Parameters:
        prefix - The namespace prefix to look up
        Returns:
        namespace URI or null if the prefix is undefined.

      • getExternallyRegisteredNamespaceURI

        protected java.lang.String getExternallyRegisteredNamespaceURI​(java.lang.String prefix)
        Given a prefix, returns an externally registered namespace URI.
        Parameters:
        prefix - The namespace prefix to look up
        Returns:
        namespace URI or null if the prefix is undefined.
        Since:
        JXPath 1.3

      • getPrefix

        public java.lang.String getPrefix​(java.lang.String namespaceURI)
        Get the prefix associated with the specifed namespace URI.
        Parameters:
        namespaceURI - the ns URI to check.
        Returns:
        String prefix

      • getExternallyRegisteredPrefix

        protected java.lang.String getExternallyRegisteredPrefix​(java.lang.String namespaceURI)
        Get the nearest prefix found that matches an externally-registered namespace.
        Parameters:
        namespaceURI - the ns URI to check.
        Returns:
        String prefix if found.
        Since:
        JXPath 1.3

      • isSealed
