Executable content is open ended in SCXML, as largely speaking most things are possible with custom actions. I'm afraid I've lost the bigger picture of your scenario in the pin-pointed question above. To obtain a node using the expression evaluator, use Evaluator#evalLocation(...) which returns a Node. >> Might be worthwhile revisiting the need for using >> SCXMLParser#newInstance() rather than the static parse methods. >> >> >> > The reason I am doing this is that I am using xinclude to include a > separate xml file and I found that I needed to call setXIncludeAware() > on the parser to make it do the include.

Based on what I've read so far, it seems your best bet may be to register the digester rules for your custom actions by hand after you obtain the new instance and let the custom action do the appropriate expression evaluation and datamodel / context processing. -Rahul > Thanks again, > -Abigail > --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
