Re: [xsl] XSLT Regex for Matching Curly Braces

Agree, if expand-text is available (if one uses XSLT 3.0, for which there is
almost no reason not to).

I think it's even clearer to use

This way you avoid complications with single and double quotes as well as
curly braces: the only characters that now have an XML or XSLT-defined special

regular expressions.
