It's a tool for identifying the node referenced by a given XPath statement (that is, what node or nodes, or none, a given XPath statement will reference, for a given document instance). To compare two XPath statements, you'd need some kind of comparative parser or tracer, which would identify the nodes referenced by each segment of the statement until the end of the statement was reached, or failure occurred. I'm not aware of any such tool, although it may well exist. ///Peter | ![]() | ![]() | ![]() |
