Hi Norman. Yes, you are right. I simply had a wrong regular expression. 
But now I have another problem:

Input: $avp(s:pai) = '<   tel:+43103   >'
(the part within '')

avp_subst("$avp(s:pai)/$avp(s:paias)","/.*<[[:blank:]]*(.*?)[[:blank:]]*>.*/\1/")

Output: $avp(s:paias) = 'tel:+43103   '

Thus, the leading whitespace is removed, but not the trailing one, but I 
can't find an error in my regular expression. Maybe some regexp experts 
out there?

thanks
