Abstract
An anchoring method for generating an XPath expression. The method can include identifying a stable anchor in the transcodable markup along an axis shared by the selected node. An XPath expression can be generated for the stable anchor. Subsequently, an offset between the stable anchor and the selected node can be computed. Finally, the XPath expression for the stable anchor and the offset can be concatenated, the concatenation forming the XPath expression for the selected node.
