json-prune within an array

[Procyon-b]

I need to remove any element of an array based on the one of its child.
This works:
##+js(json-prune, mailListElements.2 , mailListElements.2.rawData.promotext)

but this doesn't:
##+js(json-prune, mailListElements.[] , mailListElements.[].rawData.promotext)

I don't want to do this:
##+js(json-prune, mailListElements.[].* , mailListElements.[].rawData.promotext)
because it leaves an empty object in that array element and the page's script doesn't like it.

Is it at all possible without using the array index? Fortunately, ads in this array are placed in fixed position.
