pull all elements with specific name from a nested list

Question

I have some archived Slack data that I am trying to get some of key message properties. I\'d done this by stupidly flattening the entire list, getting a data.frame or tibble

Answer 1

As OP mentioned, this can solve the issue:

#Code
unlist(l)[grepl('.type',names(unlist(l)),fixed=T)]

Output:

folder_1.msg_1-1.type folder_1.msg_1-2.type folder_2.msg_2-1.type 
            "message"             "message"             "message" 

Another options are (Many thanks and credit to @Abdessabour Mtk)

#Code1
purrr::map(l, ~ purrr::map(.x, "type"))
