how to parse and serialize a string located in a transition

[Rostand <gu...@hotmail.com>]

ich want to add a String in a transition of my statemachine and write it out
too in a document after serialize the code. 
 e.g: 
<transition target="move" event="waitingForMove">
cond(received(Div_tpMsID, Div_DriverID, div_ID, '*', 'done[]'));
writeLog('INFO', '; device; Finished');
</transition>

the String i want to add is :
cond(received(Div_tpMsID, Div_DriverID, div_ID, '*', 'done[]')); 
writeLog('INFO', '; device; Finished'));

can anyone tell me how i should do this? 

thanks

Body content isn't really permissible in <transition> so the parser
just ignores it. <transition> can have executable content (as child
elements), which is a sequence of standard and/or custom actions. You
can learn more about using custom actions in the user guide here:

  http://commons.apache.org/scxml/guide/custom-actions.html

In other words, its possible to do this instead:

  <transition target="move" event="waitingForMove">
    <my:action>
      cond(received(Div_tpMsID, Div_DriverID, div_ID, '*', 'done[]'));
      writeLog('INFO', '; device; Finished');
    </my:action>
  </transition>

where <my:action> would then be parsed and serialized as expected (and
furthermore, you would be able to associate execution behavior with
the action -- this would happen when the transition is followed, based
on your requirements since you'd implement the custom action).
