So What has Changed for Paths in XPath 2.0?

Nodes can be selected by type as well as name

//entry/element()

• In XPath 1.0, type is usually implicit (except comment() and processing-instruction())
  • child::element() is the same as child::*
  • But element() has other uses
    (e.g. type-checking when defining functions)

Any expression can be used as a step

//entry/(project|work)/*

//entry/*/name()

• If not the final step, must return a sequence of nodes
  (or an error is returned)
