Accessing array's element with a key, where key is inside a collection

[Harry_Rainbird]

Hi all,

I have an array called ArticleID and I’m trying to access the “_value” in the array when the “IdType” is “doi”. I’ve tried using the map function however the key is buried inside a collection and I can’t figure out how to retrieve it. Any help would be appreciated.

You can use a formula like this,

map(ArticleId;_value;_attributes.IdType;doi)
