Re: [xsl] Performance of link target search, and Normalising or collapsing a pathname value, best method?

Hi Martin



I omitted to say that I'm currently using XSL 2 and Saxon HE. So the two Saxon
functions mentioned in your other responses are not available to me
(unfortunate, because they look like exactly what I need). The urify function
might be useful though.



To answer your question, given a $match-file="../../A/../B/../C/ccc.xml" I
would expect normalize-path($match-file) to produce "../../C/ccc.xml".



cheers

Is there a simple way of normalising that path? If necessary I can probably
write my own but there may be a function which already does it that I don't
know about.



You haven't shown how the normalized path would look like but I don't know any
such functions in the XPath 3.1 library, XProc 3 has some
https://spec.xproc.org/3.0/xproc/#f.urify which might or might not help.
