Question

How can I zip an XML file in Ruby?

For example i have a method:

def write_data(data)
  File.open(@filepath,"w") do |f|
    f.write(%[<?xml version="1.0" encoding="UTF-8"?>\n])
    f.write(%[<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">\n])
    f.write(data)
    f.write(%[</urlset>])
    f.close
  end
end

The file it creates is an XML file. I want to zip it so that it has a format test.xml.gz.

Answer 1

File.open(@filepath, 'w') do |f|
  gz = Zlib::GzipWriter.new(f)
  gz.write(%[<?xml version="1.0" encoding="UTF-8"?>\n])
  gz.write(%[<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">\n])
  gz.write(data)
  gz.write(%[</urlset>])
  gz.close
end
