to complete this, the upcoming 1.5.0 does have some new stuff that helps 
a lot in such case:
- the tobody transformation to get the params part:
http://www.kamailio.org/dokuwiki/doku.php/transformations:devel#to-body_transformations
- and param transformation to get the value:
http://www.kamailio.org/dokuwiki/doku.php/transformations:devel#parameters_list_transformations

In case of something more complex to parse and extract, the re.subst 
transformation can be used:

Daniel
