Look into HTML::Parser. HTML is very hard to find because you can have nested < >. merlyn's WebTechnique columns have many HTML::Parser examples, as did the latest issue of The Perl Journal

That said, a basic Regexp to match simple HTML is: 

/<[^>]*>/  #matches an HTML tag
#So you would want:
# 
s/(<[^>]*>[^<\s]*)\s+/$1\&nbsp;/g 
#Should match a tag followed by some non-tag, non whitespace, followed
+ by whitespace.  Untested.

You will also have to match any whitespace before the first tag, but you can probably handle that.
