;Task:
Given the name of a language on Rosetta Code, find all tasks which are not implemented in that language.
Note: Implementations should allow for fetching more data than can be returned in one request to Rosetta Code.
You'll need to use the Media Wiki API, which you can find out about locally, [http://rosettacode.org/mw/api.php here], or in Media Wiki's API documentation at, [http://www.mediawiki.org/wiki/API_Query API:Query]

This uses a couple of core libraries, and a Java method for URL encoding.
<syntaxhighlight lang="clojure">(require
'[clojure.xml :as xml]
'[clojure.set :as set]
'[clojure.string :as string])
(import '[java.net URLEncoder])</syntaxhighlight>
The ''titles-cont'' function fetches and parses an XML response, and walks over it extracting titles. It also extracts the ''cmcontinue'' value, if present. Returns a pair ''[titles,cmcontinue]''.
<syntaxhighlight lang="clojure">(defn titles-cont [url]
(let [docseq (-> url xml/parse xml-seq)]
((juxt #(filter string? %), #(-> (filter map? %) first :cmcontinue))
(for [{:keys [tag attrs content]} docseq :when (#{:cm :query-continue} tag)]
(if (= tag :cm)
(attrs :title)
(-> content first :attrs))))))</syntaxhighlight>
The ''get-titles'' function has 1- and 2-argument versions. The former takes the name of a category, composes the appropriate URL query, and calls the 2-argument version. The 2-argument version gets a title list (with possible ''cmcontinue'' value), chaining further calls as necessary into the lazy sequence result.
<syntaxhighlight lang="clojure">(defn urlencode [s] (URLEncoder/encode s "UTF-8"))
(defn param [p v] (str p (urlencode v)))
(defn get-titles
([category]
(let [urlbase "http://www.rosettacode.org/w/api.php"
params ["action=query"
"list=categorymembers"
"format=xml"
"cmlimit=200"
(param "cmtitle=Category:" category)]
url (str urlbase "?" (string/join "&" params)]
(get-titles url nil)))
([url continue-at]
(let [continue-param (if continue-at (param "&cmcontinue=" continue-at))
[titles continue] (titles-cont (str url continue-param))]
(if continue
(lazy-cat titles (get-titles url continue))
titles))))</syntaxhighlight>
The ''unimplemented'' function gets a set of all titles and of language-implemented titles and returns the difference. It uses ''future'' in order to do the necessary URL requests in parallel.
<syntaxhighlight lang="clojure">(defn unimplemented [lang-name]
(let [title-set #(future (apply sorted-set (get-titles %)))
all-titles (title-set "Programming_Tasks")
lang-titles (title-set lang-name)]

The isolation of in-browser JavaScript from system resources, and the association of JavaScript code files with particular (and already loaded) documents may mean that JavaScript is not the right tool for the broader case envisaged by this task.
For the narrower context of a browser in which the 'not implemented' page has been fetched for a particular language, we can however, evaluate an XPath expression in JavaScript to generate an array of titles for the unimplemented tasks.
<syntaxhighlight lang="javascript">(function (strXPath) {
var xr = document.evaluate(
strXPath,
document,
null, 0, 0
),
oNode = xr.iterateNext(),
lstTasks = [];
while (oNode) {
lstTasks.push(oNode.title);
oNode = xr.iterateNext();
}
return [
lstTasks.length + " items found in " + document.title,
''
].concat(lstTasks).join('\n')
})(
