XXE uses the standard regexp package of Java[tm]. See
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
The basic syntax of regexps is the same in all regexp implementations I
know. Therefore, in my opinion, there is not much to document in XXE.

This is planned. Next version of XXE (V2.11. V2.10 should be released
tomorrow) will have an enhanced Characters tool (among many other
enhancements). The feature you request is just a byproduct of these
enhancements.

Well, I'm affraid you'll have to write these commands yourself. How to
do it is described in the Developer's Guide. See
http://www.xmlmind.com/xmleditor/_distrib/docs/dev/ar01s06.html

Thanks. This is fixed now.
