Did you read my last thread?

I'm talking about <tal:anything tal:yanged="/foo/bar" /> not <tal:yanged 
tal:replace="/foo/bar" />

What I need is control the expression far away from the normal way (I 
want to process the result automatically before return the result)

Aj and Chris dissapoint me to modify the __gettattr__ member of my class 
to make this calculation

Then I thing I can make this calculation via some tal:statement

Some idea?
