XML in Indesign - how to use attributes to assign formating

I wanted to use XML to design a big festival programme. Unfortunately the XML consist only of text elements that have certain attributes (like date, time, type, etc) assigned to them.

I can rename the text elements to whatever I want to name them by selecting them and assign them a new mark. But how can I automatically do this for the entire document?

Is there a way to tell Indesign to mark the elements depending on their attributes?
