need to create an xml creator with a scrripting language

This question might not be suitable for stackoverflow but I have nowhere else to ask.

I need to create a XML-CREATOR application with C#, where users will define their own TAGS and RULES by a scripting language. The data will be in a database table. When the user finishes TAGS and RULES definitions, the application will start selecting data and creating the XML according to the TAGS and RULES.

I searched on google and I saw that IronPython might be handy in this case. Do you guys have any experience? I have no idea how to start or what tech I need to use?
