Hi;
I am just coming up to speed on Regex and have a
couple of questions, 
please.

1. Is there a difference between a) [a-cx-z] and
b)[a-c[x-z]] ?
If so, what? If not, which syntax is better to use?
   

I don't know, but b) looks confusing to me.  I'd go
with a).
 

This is the reason I am confused. 
http://java.sun.com/docs/books/tutorial/extra/regex/char_classes.html
If you look under the union (and other) section on that page, they 
consistently use b), hence my question.

2. How do I uppercase (or lowercase) a character in
a string? (Need to 
do this in Ant, so the Java string functions are not
helpful.)
   

There is some information on this here:
http://issues.apache.org/bugzilla/show_bug.cgi?id=32582
 

This issue is regarding a non-regex feature request. But, I hope that 
generic regex can do this, as well..
Thanks;

HTH,

Thank you;
