Sitemap (sitemaps.org) generator for Middleman

sitemap.xml.erb

<% pages = sitemap.resources.find_all{|p| p.source_file.match(/\.html/) } %>
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<% pages.each do |p| %>
  <url>
    <loc>http://youdomain.com/<%=p.destination_path.gsub('/index.html','')%></loc>
    <priority>0.7</priority>
  </url>
<% end %>
</urlset>

For anyone coming across this recently, I had to modify the suggestion above to work with redirects. My sitemap.xml.erb file looks like this:

---
layout: false
directory_index: false
---
<% pages = sitemap.resources.reject{|r| r.is_a? Middleman::Sitemap::Extensions::RedirectResource }.find_all{|p| p.source_file.match(/\.html/) && !p.data.sitemap_noindex == true } %>
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<% pages.each do |p| %>
  <url>
    <loc>https://example.com<%=p.url.gsub('/index.html','')%></loc>
    <changefreq>monthly</changefreq>
    <priority><%= p.data.sitemap_priority || 0.5 %></priority>
  </url>
<% end %>
</urlset>
