Pre-processing of any sort can be done to the SCXML document before
being handed to the library ofcourse. It seems something like XML
entities may help you here (but I'll need help understanding the
question first).

You will have to do some pre-processing since this kind of
substitution is not provided as a feature by Commons SCXML. One could
imagine a number of technologies (generate a DTD or DOCTYPE with
entities, straight text replacement etc.) that will allow setting up
of such pre-processing, so in that sense it almost seems beyond the
scope of the core library function.

You will have to do some pre-processing since this kind of
substitution is not provided as a feature by Commons SCXML. One could
imagine a number of technologies (generate a DTD or DOCTYPE with
entities, straight text replacement etc.) that will allow setting up
of such pre-processing, so in that sense it almost seems beyond the
scope of the core library function.

RE: SCXML : can we use ${prop-name-attributes} within definition ?
Posted by "Renaud, Martin" <Ma...@nuance.com>.
Hi Rahul,
Thanks for answering.
I want to avoid repeating the event name twice, because of the typo risks (among others).
For example, once in the state machine definition:
<state id="MyState">
<transition event="core.request.sent" target="MySecondState"/>
</state>
And again in the code:
public static String EVENT_NAME = "core.request.send";
...
mySM.fireEvent(EVENT_NAME)
The names are different (send/sent).
I could easily inject the names in my java code using spring and a property file. EX:
event.name.foo=core.request.sent
and use the property name ${event.name.foo} where I need in spring files and use some bean to trigger the events. I would like to know if there is a similar substitution mechanism that allows me to use to a property file (the same in this case) against my state machine definition.
I understand that I can pre-process the xml document before handing it to scxml, but I wanted to know if this feature exists or is being plan.
Thanks,
Martin

Pre-processing of any sort can be done to the SCXML document before
being handed to the library ofcourse. It seems something like XML
entities may help you here (but I'll need help understanding the
