While I agree xslt is the proper way, I also immediately know the sed
syntax.  So here goes:

/<refpurpose>/{
 :loop
   /<\/refpurpose>/b break
   N
   b loop

 :break
   s,^.*<refpurpose>,,
   s,</refpurpose>.*$,,
   s,\(^[[:space:]]*\|[[:space:]]*$\),,g
   s,[[:space:]]\+, ,g
   p
   q
}

Save to file and use like this:
$ sed -n -f foo.sed < foo.xml
