如何在Clojure中将Enlive对象转换为JSON对象？

(ns my-namespace
  (:require [clojure.data.json :as json]
            [clojure.java.io :as io]
            [net.cgrand.enlive-html :as enlive]))

(defn extract-data [html]
  (-> html
      (enlive/html-resource)
      (enlive/select [:div#my-div])
      (enlive/first)
      (enlive/text-content)))

(defn transform-data [data]
  {:content data})

(defn to-json [data]
  (json/write-str data))

(let [html "<div id='my-div'>Hello, World!</div>"
      data (extract-data html)
      json-object (to-json (transform-data data))]
  (println json-object))
