How to find and replace using a regular expression to remove an attribute in a specific xml tag

I am working with an xml file with a couple iterations of:

<Create key="*insert_characters*">

I would like to have all of these tags to just read:

<Create>

I pretty much want to remove all attributes with only the Create element. I apologize but I am not too familiar with regular expressions and hope this question hasn't been answered already. I am trying to use the Regular Expression search mode on notepad++.

Any thoughts or opinions are much appreciated. Thanks.
