Hi,

I have to filter out  the string after the last ','  from a  set input
string data ,

for example <data>a.b.abc</data>
                   <data>c.de.f</data>
                    <data>st.uvw.xy</data>
                   ...

results:  abc , f,xy...
                  ..

I can use substring-after and substring-before function  with recursive
procedures to get this job done.

However I wonder is there an intelligent way to get
what I am trying to achieve?

Thanks in advance.
