<xsl:variable name='Name.re'
select='concat($NameStartChar.re,
"(", $NameChar.re,")*")'/>
Why not use '\i' and '\c' from
http://www.w3.org/TR/xmlschema-2/#charcter-classes?
For which range please Tony? Err....
\i includes : which is wrong?
\c looks good though! Ah no. Again it's NameChar from
http://www.w3.org/TR/2000/WD-xml-2e-20000814#NT-NameChar
which is more than allowed for xsl:variable @name?
Otherwise, you may want '(' and ')' around $NameStartChar.re in $Name.re,
otherwise (to mix variable expansions) it looks like
'...|[‿-⁀]($NameChar.re)*" and you'll only match
multi-character names when they begin with a character in the range
[‿-⁀].
As I read it (or more accurately fail to read it correctly)
It's NameChar less :
followed by (Name less :)+
Simpler version [A-Za-z0-9]+ and the i18N additions,
but I can't get the simpler one working.
It's only matching on the first letter of a variable currently....
<xsl:variable select="$fred"/>
Produces
"xsl:variable"
[f]
"xsl:variable"
[r]
"xsl:variable"
[e]
"xsl:variable"
[d]
so something is seriously wrong.
