#* 
How would you refactor this? 

This code is workflow, which moves through a set of tasks: the config hash is a list of XML documents to convert into the database kept in YAML, before() does some setup work, download_xmls fetches hundreds of XML documents based on the config, the convert method does a lot of transformation work from xml into AR (and sometimes fetches further XML documents). Finally a report is generated and emailed to recipients to represent how the run went.

It began as a practical way to code an integration between an XML service and the app., now it's smelly. I obviously need a task based DSL, probably a state machine lib.. Any other ideas of a good DSL or library which could be adopted for it?
