Please use the code button when sharing code.

Use the filter hook and write your own filter function.
In buddypress\bp-xprofile\bp-xprofile-template.php
find the filter hook in function bp_the_profile_field_value()

BP uses that same hook for a lot of formatting. See buddypress\bp-xprofile\bp-xprofile-filters.php
So be sure to set the priority to a high number like 99 so your filter function will run last.
