Hi Dave,

If you feel to attach the code in this email instead, would you please directly include the script as text in the email or change the affix to txt? Thanks so much and sorry for the inconvenience!

Hi Dave,

Thanks so much for your response!!! 

The test02.py was removed by the bank due to policy. Would you please send it to my personal email: dev...@ya...? 

Sorry for any inconvenience!

Devin,

Good to hear from you.

Here is a suggestion -- Create your own version of the `parse` function that is defined inside a module generated by `generateDS`.
In your custom version, you would explicitly set `rootTag` and `rootClass` for the specific XML instance document to be parsed.
I've attached a example that might give you ideas on how to do that.
See my comments in that attached example.

Hope this helps.  Let me know how it goes and if you have more questions.

Dave
