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.
