I'm still new at this, thanks for any help. The following line extracts a value from a data structure:
(:value (first (filter #(= (:name %) "abc") input-attrs))) *input-attrs* is a seq of hashes that for example looks like: ({:src "a.png", :name "abc", :value "a"} {:name "def", :src "b.gif", :value "b"}) This is test data; the real data will have this structure but have more hashes. My goal is to return the :value value when a specific :name value is specified. The first line above is how to extract the :value value when :name = "abc". The problem is that I need to extract 2 :value values for 2 distinct :name values from this one structure. The structure is moderately expensive to construct, so while I have it built I'd like to pull everything out of it that I need at once. It struck me that I should pass a vector of :name values to this function and have some sort of *for *or *map *process the vector over this extraction. But I cannot seem to write that correctly. It also struck me that once I can do the extractions correctly that I should probably pass a list of hashes back that has the result, such as: ({name "abc", :value "a"} {:name "def" :value "b"}) But then that looks curiously very similar to the original structure (minus unmatched hashes and some unneeded other values). Am I just thinking about this "wrongly"? Thanks for any help. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
