If used with [1] as in (//e)[1] then probably not much, in either case the system will stop once it comes to the first e, but if you compare /a/b/c/d/e and //e then the first will only need to search teh document to a fixed depth to look for e's whereas //e will always have to search the entire document. You may know that a ,z> element never has any e descendents, but the system doesn't and so will have to look everywhere 9including inside e elements) to check for e children On big documents that can be quite a hit. In your table example you know I think that entry are always two levels down from table so table/*/*/entry is likely to be a lot nicer to the system than table//entry.
