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>

Aaaaaaaand here goes HAML:

---
layout: false

---
- pages = sitemap.resources.find_all{ |page| page.source_file.match(/\.haml/) }
!!! XML
%urlset{ :xmlns => "http://www.sitemaps.org/schemas/sitemap/0.9" }
  - pages.each do |page|
    %url
      %loc
        =page.destination_path.gsub("/index.html", "")
      %priority
        0.7

If the !!!xml doesnt generate the corresponding tag, just write it in plain text.

Alternatively for people working with a navigation built on data files is an approach inspired by a blog post I just found:

---
layout: false

---
<?xml version="1.0" encoding="UTF-8"?>
-today = Time.new.iso8601
%urlset{ :xmlns => "http://www.sitemaps.org/schemas/sitemap/0.9" }
  -sitemap.app.data.navigation.items.each do |page|
    %url
      %loc
        =sitemap.app.config.deployment_url + page.url
      %priority
        0.7
      %changefreq
        "monthly"
      %lastmod
        = today

sitemap.app.config << means I :set deployment_url, "$actualUrl" in my config, another nice way I found worth mentioning.

For anyone stumbling across this who is using redirects, you might want to update the method which fetches pages to something like:

<% pages = sitemap.resources.reject{|r| r.is_a? Middleman::Sitemap::Extensions::Redirects::RedirectResource }.find_all{|p| p.source_file.match(/\.html/) } %>

Works great!

There are three things I would want to achieve further

• In case of using directory_indexes, the root path still shows index.html in the end
• How to hide certain pages from sitemap (preferably using frontmatter)
• How to set page specific priority (preferably using frontmatter)

Incase of directory_indexes using url instead of destination_path does the trick

<loc>http://youdomain.com<%=p.url.gsub('/index.html','')%></loc>

I tweaked this gist to the following code for sitemap.xml.erb it works with directory indexes and has ability to hide pages from sitemap and set priorities for each page from frontmatter, priority defaults to 0.5

---
layout: false
directory_index: false

---
<% pages = sitemap.resources.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>http://balcozy.com<%=p.url.gsub('/index.html','')%></loc>
    <changefreq>monthly</changefreq>
    <priority><%= p.data.sitemap_priority || 0.5 %></priority>
  </url>
<% end %>
</urlset>

In page.html.erb use sitemap_noindex: true and sitemap_priority: whenever needed

---
sitemap_noindex: true
sitemap_priority: 0.8

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>
