;; There should be no space between the \ and the &, but I don't know how ;; to create that in an example yet. (clojure.string/escape "I want 1 < 2 as HTML, & other good things." {\< "&lt;", \> "&gt;", \& "&amp;"}) "I want 1 &lt; 2 as HTML, &amp; other good things."

(ns test1.core (:require [clojure.string :as str])) (def text1 "Hello Clojure World!") ;; Escape each character '!' (str/escape text1 {\! "!!!"}) ;; => "Hello Clojure World!!!" ;; Escape each space character (str/escape text1 {\ "-"}) ;; => "Hello-Clojure-World!" ;; Escape each characters '!' or space (str/escape text1 {\! "!!!" \ "-"}) ;; => "Hello-Clojure-World!!!"

;; Note it correctly handles the case where a replacement string contains ;; a char that’s in the replacement map: (clojure.string/escape "123" {\1 "2" \2 "3" \3 "4"}) ;; => "234" (clojure.string/escape "ab" {\a "b" \b "a"}) ;; => "ba"

;; Escape can be called with a function as the second argument. (defn convert [val] (case val \a \B \b \A \C)) (clojure.string/escape "ab" convert) ;; => "BA" (clojure.string/escape "ak" convert) ;; => BC
