Selectable methods for generating robust XPath expressions
First Claim
1. A computer system for generating robust XPath expressions for a selected node in transcodable markup, comprising:
- a set of differing XPath expression generators;
an interface through which at least one of said XPath expression generators can be selected; and
,an XPath generator processor configured to apply each of said selected XPath expression generators to the selected node in the transcodable markup to produce a redundant set of robust XPath expressions configured to identify the selected node.

Abstract
A method and system for generating robust XPath expressions for a selected node in transcodable markup. The system of the invention can include a set of differing XPath expression generators; an interface through which at least one of the XPath expression generators can be selected; and, an XPath generator processor configured to apply each of the selected XPath expression generators to the selected node in the transcodable markup to produce a redundant set of robust XPath expressions configured to identify the selected node. Notably, the system also can include an XPath resolution processor. The XPath resolution processor can resolve each XPath expression in the redundant set. The resolutions, in turn, can identify a set of candidate nodes, the XPath resolution processor identifying the selected node from among the set of candidate nodes based upon the XPath expressions resolving to the selected node more than any other node in the set of candidate nodes.

7. A computer-implemented method of generating robust XPath expressions comprising the steps of:
-
selecting a node in transcodable markup; further selecting at least two XPath expression generation methods, each said method having a configuration for producing XPath expressions which uniquely identify nodes in transcodable markup; and
,generating a redundant set of XPath expressions for said selected node using said further selected XPath expression generation methods. - View Dependent Claims (8)

9. A machine readable storage having stored thereon a computer program for generating robust XPath expressions, said computer program comprising a routine set of instructions for causing the machine to perform the steps of:
-
selecting a node in transcodable markup; further selecting at least two XPath expression generation methods, each said method having a configuration for producing XPath expressions which uniquely identify nodes in transcodable markup; and
,generating a redundant set of XPath expressions for said selected node using said further selected XPath expression generation methods. - View Dependent Claims (10, 11)
