Usage

require 'sitemaps'

# parse a sitemap from a string
Sitemaps.parse("<xml ns=\"...")

# fetch and parse a sitemap from a known url
sitemap = Sitemaps.fetch("http://termscout.com/sitemap.xml")

# fetch and parse sitemaps, excluding paths matching a filter, and limiting to the top 200 
sitemap = Sitemaps.fetch("https://www.digitalocean.com/sitemaps.xml.gz", max_entries: 200) do |entry|
  entry.loc.path !~ /blog/i
end

# attempt to discover sitemaps for a site without a known sitemap location. Checks robots.txt and some common locations.
sitemap = Sitemaps.discover("https://www.digitalocean.com", max_entries: 200) do |entry|
  entry.loc.path !~ /blog/i
