        Parameters:
        contextNode - the context node (a document can also be used)
        expression - the XPath expression
        Returns:
        the selected node list

        Description copied from interface: JRXPathExecuter
        Selects an object by evaluating an XPath expression on a context node.

        If the expression evaluates to a node list, the first node in the list should be returned. Otherwise, the primitive value resulted from the evaluation should be returned as a java.lang.String, java.lang.Number or java.lang.Boolean.
