Hello,
I posted this question to StackOverflow, and one commenter suggested that
this was a more appropriate place to ask this question
(http://stackoverflow.com/questions/42940811/select-nested-xml-element-where-nested-tag-is-the-same-name-using-clojure-data-z)
I have a bit of XML that I'm wrangling using clojure.data.zip.xml. That XML
has elements with the same name as nested elements:
<things>
<thing>
<thing>Want this</thing>
<thingattr>...but not this</thingattr>
</thing>
<thing>
<thing>Select this</thing>
<thingattr>...again, not this</thingattr>
</thing>
</things>
However, accessing the inner element seems to be beyond my reach with the
xml-> function in clojure.data.zip.xml. If, however, the nested element
does not share the same name as the parent, all works as expected:
(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.
I suspect that this may be an unaddressed case in clojure.data.zip.xml, but
I am hoping that someone can show me the proper usage if I am simply
misunderstanding how to use the library.
Kind regards,
Peter
