Using Enlive for sitemaps - multilingual/regional sitemaps having xhtml:link tags

[Kai]

Hi all,

I'm trying to use Enlive to generate a multilingual, multi-regional sitemap following the Google spec/example here: 

https://support.google.com/webmasters/answer/2620865?hl=en

...and not having much progress.  Say my template file looks like this,

<?xml version="1.0" encoding="UTF-8"?>

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"

        xmlns:xhtml="http://www.w3.org/1999/xhtml">

    <url>

        <loc>http://www.example.com/english/</loc>

        <xhtml:link

            rel="alternate"

            hreflang="de"

            href="http://www.example.com/deutsch/" />

        <xhtml:link

            rel="alternate"

            hreflang="en"

            href="http://www.example.com/english/" />

    </url>

</urlset>

Now, it looks to me like one deftemplate (for urlset tag) and two snippets (outer loop of url tag, inner loop of xhtml:link tags) should do the job, but exactly what selectors to use, is stumping me.  This code, for example, does not work to produce the expected/desired sitemap:

(require '[net.cgrand.enlive-html :as html])

(html/defsnippet xhtml-link-snippet "sitemap-mlmr.xml"

  [:xhtml:link]

  [hreflang-m]

  [:xhtml:link] (html/set-attr :hreflang (:hreflang hreflang-m)

                               :href (:href hreflang-m)))

(html/defsnippet url-snippet "sitemap-mlmr.xml"

  [:url] 

  [url-m]

  [:loc] (html/content (:loc url-m))

  [[(html/nth-last-child 1)]] (html/content (map xhtml-link-snippet

                                                 (:hreflang-list url-m))))

(html/deftemplate sitemap-mlmr "sitemap-mlmr.xml"

  [url-list]

  [:urlset] (html/content (map url-snippet url-list)))

(def sample-urls

  [{:loc "http://example.com/de/de"

    :hreflang-list [{:hreflang "en" :href "http://example.com/de/en"}

                    {:hreflang "de-de" :href "http://example.com/de/de"}]}

   {:loc "http://example.com/de/en"

    :hreflang-list [{:hreflang "de-de" :href "http://example.com/de/de"}

                    {:hreflang "en" :href "http://example.com/de/en"}]}

   ])

(reduce str (sitemap-mlmr sample-urls))

The self-closing xhtml:link tag seems to cause issues, but is not the only problem.  Any tips/help appreciated, thanks!
