Saxon has introduced the extension function replace-with() which allows
replace-with($in, '^.', function($x){upper-case($x)})

Dear list,
I need to convert the first character of a string from lower-case to
upper-case. I know that I can do so with the following code:
concat(upper-case(substring(.,1,1)),substring(.,2))
I was wondering whether it can also be done with the replace() function,
i.e., with a regular expression. I found out that some regular expression
versions have the command \u for that. So I tried the following:
replace(.,'^(.)','\u$1')
But this produces an error with Saxon ("FORX0004: Invalid replacement string
in replace(): \ character must be followed by \ or $"). Does this mean that
case conversion is not available in the regular expression version
implemented in XSLT? Or did I get the code wrong?
Thanks in advance for your help!
