[xsl] [ANN] XPathle

["Imsieke, Gerrit, le-tex gerrit.imsieke@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Those of you who've been to XML Prague already know it: My demojam 
contribution is a Wordle-inspired game, written -- of course -- in XSLT 
and running in the browser using SaxonJS.

It's not just fun, but also educational. See for example the difference 
between
//li[position() mod 3 = 0]
and
/descendant::li[position() mod 3 = 0]
or
(//li)[position() mod 3 = 0]
when applied to the second example.

I cannot promise that there will be a "daily" challenge each and every 
day. But please send me links to XML files on Github or elsewhere, 
together with secret XPaths, and I will use them as input for the daily 
challenge, with some attribution if you don't object.

The distance calculation used to be so buggy, it haunted me until today 
when I finally got it right (which I thought at least five times already 
in the past 10 days). If it doesn't compute the distances as you'd 
expect them to be from the documentation, please file a bug report.
