Re: [xsl] xslt 2.0 regex

It seems to me that in this subexpression:

    | - | . | [0-9]

The dot needs to be escaped. Dot is a special character and in its
unescaped form means "accept any character at the current position".
On the other side:

\.

means literally the dot character.

Good catch Dimitre. Thanks.
It's still not working

The regex-group(0) isn't reporting the variable name?
Surrounding with () hasn't helped, to use -group(1) either.
