What is the best way to associate by to a list if key is present multiple times

associateBy(keySelector = { it.getAttributeValue(“name”) }, valueTransform = { it.getAttributeValue(“value”) ?: “” })

[marstran]

What do you want to do if the key is there multiple times?

[fstn]

I want the value to be a list of all values

[kevinmost]

I think you want groupBy

[marstran]

You could probably use groupBy, or groupingBy if you want to avoid immediate collections.
