Re: xslt 2.0 regex

Both XSLT 1.0 and 2.0 define variable names as QNames, so they *can*
have a ":" in them.

Agreed. My misread of the spec.
Tks Brandon.

Ignoring that for the moment, though, Tony pointed out one consequence
of this, but the bigger issue is that the "|" operator in regex is
fairly low precedence, so you often need some parenthesis around the
list of alternatives to get things right.  Your NameStartChar.re has a
hex-char-ref-encoded "$" at the beginning, so that regex is actually
"$[A-Z] | _ | [a-z] | ...", which means it will match "(a dollar sign
followed by an upper-case English letter) or (an underscore) or (a
lower-case English letter) or ...".

Actually, it might not even match that, since the "$" is a special
character in regex, so you should escape it with a backslash to match
it literally (though I think there are some rules which allow it to
match literally even without the backslash, depending on what follows
it, but best to be explicit).

All that said, I got this to work by dropping the "$" from the start
of NameStartChar.re and changing Name.re to:

concat("\$(", $NameStartChar.re, ")(", $NameChar.re,")*")

-Brandon :)

presumably because $ is within the a-z grouping....
Yes it works.
