私の結果をどのようにトラバースできますか？

Question

これは私が現在持っているものです。

私は結果からこれを持って、それを横断したかったです。

Answer 1

いいえ、XMLではありません。 get-inを使用すると、ネストされた構造をトラバースできます。

Answer 2

@jmargolistvtによると、xmlではなく、Clojureデータ構造（ネストされたマップ&配列）があります。

printlnなどの代わりにprnを使用して印刷してください。「Harper Voyager」のような文字列に二重引用符を使用することが重要です。得

(ns clj.core 
    (:require 
    [tupelo.core :as t] 
    [clojure.pprint :as pp] 
    ) 
    (:gen-class)) 
(t/refer-tupelo) 

(def data 
    {:total-pages 1, :total-results 1, :items 
    [ {:item-atributes 
      {:title "Tolkien Calendar 2017", :product-group "Book", 
      :manufacturer "Harper Voyager" 
      :author "J. R. R. Tolkien" }, :SalesRank 12016, :item-links [{:description "Technical Details" } ] 
    } ] }) 


(pp/pprint data) 

(defn -main [& args] 
) 

：

~/clj > lein run  
{:total-pages 1, 
:total-results 1, 
:items 
[{:item-atributes 
    {:title "Tolkien Calendar 2017", 
    :product-group "Book", 
    :manufacturer "Harper Voyager", 
    :author "J. R. R. Tolkien"}, 
    :SalesRank 12016, 
    :item-links [{:description "Technical Details"}]}]} 

をこの時点では、あなたが取得する

(newline) 
(doseq [item (data :items) ] 
    (newline) 
    (pp/pprint item) 
    (newline) 
    (spyx (item :SalesRank)) 
    (spyx (get-in item [:item-atributes :title]))) 

を追加することができます。

は、私がデータを少し単純化し、これを持って

{:item-atributes 
{:title "Tolkien Calendar 2017", 
    :product-group "Book", 
    :manufacturer "Harper Voyager", 
    :author "J. R. R. Tolkien"}, 
:SalesRank 12016, 
:item-links [{:description "Technical Details"}]} 

(item :SalesRank) => 12016 
(get-in item [:item-atributes :title]) => "Tolkien Calendar 2017" 

あなたproject.cljこれは(spyx ...)パートの仕事にするために含まれている必要があります

:dependencies [ 
    [tupelo "0.9.9"] ...
