Hi Erwin,
It looks like your XML is of the kind ‘name-value pairs’. This means that all your attributes will be imported as a list of attributes under your list attribute.
What you should do is
It will look something like this:
if name = confProdRequiresApproval then change confProdRequiresApproval in Mendix with the value from that object.
Do this for every element known attribute in your list and you are done.
