XmlSitemap

XmlSitemap is a ruby library that provides an easy way to generate XML sitemaps and indexes.

It does not have any web-framework dependencies and could be used in any ruby-based application.

Installation

Install via rubygems:

gem install xml-sitemap

Or using latest source code:

rake install

Configuration

Add gem to your Gemfile and you're ready to go:

gem 'xml-sitemap'

Usage

Simple usage:

map = XmlSitemap::Map.new('domain.com') do |m|
  # Adds a simple page
  m.add '/page1'  

  # You can drop leading slash, it will be automatically added
  m.add 'page2'

  # Set the page priority (default is 0.5)
  m.add 'page3', :priority => 0.2

  # Specify last modification date and update frequiency
  m.add 'page4', :updated => Date.today, :period => :never
end

Render map output:

# Render the sitemap XML
map.render

# Render and save XML to the output file
map.render_to('/path/to/file.xml')

# You can also use compression
map.render_to('/path/to/file.xml.gz', :gzip => true)

# If you didnt specify .gz extension to the filename,
# XmlSitemap will automatically append it
# => content will be saved to /path/to/file.xml.gz
map.render_to('/path/to/file.xml', :gzip => true)

You can also create a map via shortcut:

map = XmlSitemap.new('foobar.com')
map = XmlSitemap.map('foobar.com')

By default XmlSitemap creates a map with link to homepage of your domain.

Homepage priority is 1.0. Default page priority is set to 0.5

List of available update periods:

• :none
• :always
• :hourly
• :daily
• :weekly
• :monthly
• :yearly
• :never

Generating Maps

When creating a new map object, you can specify a set of options.

map = XmlSitemap::Map.new('mydomain.com', options)

Available options:

• :secure - Will add all sitemap items with https prefix. (default: false)
• :home - Disable homepage autocreation, but you still can do that manually. (default: true)
• :root - Force all links to fall under the main domain. You can add full urls (not paths) if set to false. (default: true)
• :time - Provide a creation time for the sitemap. (default: current time)
• :group - Group name for sitemap index. (default: sitemap)

Render Engines

XmlSitemap has a few different rendering engines. You can select one passing argument to render method.

Available engines:

• :string - Uses plain strings (for performance). Default.
• :builder - Uses Builder::XmlMarkup.
• :nokogiri - Uses Nokogiri library. Requires nokogiri gem.

Sitemap Indexes

Regular sitemap does not support more than 50k records, so if you're generating a huge sitemap you need to use XmlSitemap::Index.

Index is just a collection of links to all the website's sitemaps.

Usage:

map = XmlSitemap::Map.new('domain.com')
map.add 'page'
    
index = XmlSitemap::Index.new

# or via shortcut
index = XmlSitemap.index

# Add a map to the index
index.add(map)

# Render as XML
index.render

# Render XML to the output file
index.render_to('/path/to/file.xml')
