我有一些我正在使用的 XML clojure.data.zip.xml。该 XML 具有与嵌套元素同名的元素:

<things>
  <thing>
    <thing>Want this</thing>
    <thingattr>...but not this</thingattr>
  </thing>
  <thing>
    <thing>Select this</thing>
    <thingattr>...again, not this</thingattr>
  </thing>
</things>

xml->但是,使用clojure.data.zip.xml 中的函数访问内部元素似乎超出了我的能力范围。但是,如果嵌套元素与父元素不使用相同的名称,则一切都按预期工作:

(ns xmlzip.core
  (:require [clojure.xml :as xml]
            [clojure.zip]
            [clojure.data.zip.xml :as z])
  (:gen-class))

(defn parse [s]
  (clojure.xml/parse
   (java.io.ByteArrayInputStream. (.getBytes s))))

(def example1 (clojure.zip/xml-zip (parse "
<things>
  <thing>
    <thing>Want this</thing>
    <thingattr>...but not this</thingattr>
  </thing>
  <thing>
    <thing>Select this</thing>
    <thingattr>...again, not this</thingattr>
  </thing>
</things>
")))

(def example2 (clojure.zip/xml-zip (parse "
<things>
  <thing>
    <subthing>Want this</subthing>
    <thingattr>...but not this</thingattr>
  </thing>
  <thing>
    <subthing>Select this</subthing>
    <thingattr>...again, not this</thingattr>
  </thing>
</things>
")))


(z/xml-> example2 :thing :subthing z/text)
;; ("Want this" "Select this") ;hooray!

(z/xml-> example1 :thing :thing z/text)
;; ("Want this...but not this" "Select this...again, not this") ;boo, hiss.

我怀疑这可能是一个未解决的案例clojure.data.zip.xml,但如果我只是误解了如何使用该库,我希望有人能告诉我正确的用法。
