I don’t know your exact requirement to use info engine to get workflow activity information.
I had similar requiring for one cognos report, where I have to use info engine to get workflow related information using info Engine. It’s tedious to write webjects to retrieve all workflow related information when you have API’s easily available. I wrote one helper class to retrieve all require information using API. Call helper class from task/xml file, which with return result in infoengine group.
So you can use the xml/task for cognos reports, web service or for any other purpose.
