        This method is similar to findNodeType(int, Object) except that it creates a StepPattern instead of just returning a node type. It also differs in the way it handles "{uri}:*" and "{uri}:@*". The last two patterns are expanded as "*[namespace-uri() = 'uri']" and "@*[namespace-uri() = 'uri']", respectively. This expansion considerably simplifies the grouping of patterns in the Mode class. For this expansion to be correct, the priority of the pattern/template must be set to -0.25 (when no other predicates are present).
      • findNodeType

                                      throws java.lang.Exception
        Parse the expression passed to the current scanner. If this expression contains references to local variables and it will be compiled in an external module (not in the main class) request the current template to create a new variable stack frame.
        Parameters:
        lineNumber - Line where the current expression is defined.
        external - Set to true if this expression is compiled in a separate module.

      • isElementAxis

        public boolean isElementAxis​(int axis)
        Returns true if the axis applies to elements only. The axes child, attribute, namespace, descendant result in non-empty nodesets only if the context node is of type element.
