You desire it, and guess what, contrary to your assertion, $arg2 *can* 
be a regex character. Just put the function together yourself, along 
lines suggested by other respondents. You're in a great position with 
the XQuery/XPath/XSLT stack because you can make your own functions, and 
your imagination is the limit. The standard function library is like a 
set of Lego bricks. It's up to you to dream away, and snap the functions 
together to build your creations.

For example, there have been cases where I want normalize-space() not to 
trim space on the front and end, but to reduce it to a single space. 
Rather than complain that normalize-space() doesn't behave the way I 
wish it would, I can write that function myself, package it as 
myfunct:normalize-space(), and carry on.

Best wishes,

Joel
