(Actually, I don't know why #xHHHH is used here: it would be better to
use U+HHHH to emphasize that these are characters not codes in the

For a simple regex, adapt these ones, which are based on the XML 1.1 rules. The main things the naming checking needs to do is to prevent numbers and symbols from starting the name, and to prevent spaces and silliness inside the name. The XML 1.0 rules are much more complicated but are a restriction of these.
