I’m having trouble searching xml in a pure client-side fashion. I’ve been vacillating between using browser-based DOM functionality for this, trying to leverage Closure, and trying to leverage clojure.data.xml. I can get and read the XML in each of these ways, but I’m struggling to search it. In my …

You can convert the HTMLCollection object to a clojure sequence with array-seq, and then map over like you normally would. (comment (let [s "<title>one</title> <title>two</title> <title>three</title>" p (js/DOMParser.) doc (.parseFromString p s "text/html") html-collection…

Yeah, navigating XML is tedious… Feel free to contribute a CLJS or CLJC engine to xml-pull :wink:

I’m thinking of trying to port Enlive to CLJS; a real shame it isn’t here already

Have you considered an XPath library?

Hickory example: (ns demo.scratch (:require [hickory.core :as h] [hickory.select :as s])) (comment (let [s "<title>one</title> <title>two</title> <div><title>three</title></div>" tree (-> s h/parse h/as-hickory) title-elements (s/select (s/tag :title) tree)] (ma…

You can also use zippers. Here’s an example from Stack Overflow . Probably don’t need io/reader and instead of x/parse might have to use x/parse-str. Caveat: I haven’t tried this out yet myself.

[image] Webdev_Tory: I’ve been vacillating between using browser-based DOM functionality for this, trying to leverage Closure, and trying to leverage clojure.data.xml . In ClojureScript, clojure.data.xml uses the browser’s DOMParser. If the run-time cost of conversion to Clojure data is OK, …

+1 for showing me xml-seq. This works as a clojure-native searching method, but still lacks the advanced searching of something like xpath e.g. it’s non-trivial to perform a query like “All title nodes that are under doc.type=movie”. Or maybe I just need to embrace a more clojure way of thinking her…

Working in ClojureScript, in a browser, there’s no dishonor in using the browser’s built-in XPath. In “pure Clojure”, Enlive accomplished something more flexible than XPath with zippers, but Enlive’s notation will seem abstruse unless it’s obvious that XPath would have been harder. (The zippery pa…

sadly, xml-seq appears to be CLJ only, not cljs
