static NodePointer	SimplePathInterpreter.interpretSimpleExpressionPath(EvalContext context, NodePointer root, Expression[] predicates, Step[] steps) Interpret the steps of a simple expression path that starts with the given root, which is the result of evaluation of the root expression of the expression path, applies the given predicates to it and then follows the given steps.
