      • getChildAxisIterator

        java.util.Iterator getChildAxisIterator​(java.lang.Object contextNode,
                                                java.lang.String localName,
                                                java.lang.String namespacePrefix,
                                                java.lang.String namespaceURI)
                                         throws UnsupportedAxisException
        Retrieve an Iterator that returns the child XPath axis where the names of the children match the supplied name and optional namespace.

        This method must only return element nodes with the correct name.

        If the namespaceURI is null, no namespace should be used. The prefix will never be null.

        Parameters:
        contextNode - the origin context node
        localName - the local name of the children to return, always present
        namespacePrefix - the prefix of the namespace of the children to return
        namespaceURI - the namespace URI of the children to return
        Returns:
        an Iterator capable of traversing the named children, or null if none
        Throws:
        UnsupportedAxisException - if the child axis is not supported by this object model
      • getAttributeAxisIterator

        java.util.Iterator getAttributeAxisIterator​(java.lang.Object contextNode,
                                                    java.lang.String localName,
                                                    java.lang.String namespacePrefix,
                                                    java.lang.String namespaceURI)
                                             throws UnsupportedAxisException
        Retrieve an Iterator that returns the attribute XPath axis where the names of the attributes match the supplied name and optional namespace.

        This method must only return attribute nodes with the correct name.

        If the namespaceURI is null, no namespace should be used. The prefix will never be null.

        Parameters:
        contextNode - the origin context node
        localName - the local name of the attributes to return, always present
        namespacePrefix - the prefix of the namespace of the attributes to return
        namespaceURI - the URI of the namespace of the attributes to return
        Returns:
        an Iterator capable of traversing the named attributes, or null if none
        Throws:
        UnsupportedAxisException - if the attribute axis is not supported by this object model
