Hi Christine, In principle, in XPath, "./." is the same as "." and returns the context item. There is a minor difference, in that "./." will return an error if the context item is not a node, but in the case of the query at hand, it should always be an element node. Replacing "./." with "." produced the same results on my side.
I'd definitely wait for Mike's answer before concluding on this though, because he'll probably see something I haven't. :-) Kind regards, Ghislain > On 31 Oct 2016, at 17:52, Schwartz, Christine <[email protected]> > wrote: > > Hi, > > I'm hoping someone on this list can clarify my conundrum. > > I'm working with a colleague on a writing project and one of his examples > uses this XPath syntax "./." in the starts-with() function within an XSLT > stylesheet.
