Ruby XML::Builder with hyphen in Element name

Question

I'm trying to generate some XML using XML::Builder, but my element names need to have hyphens in it.

When I try I get undefined methods, with the element name being truncated at the hyphen

xml.instruct!

xml.update-manifest do
  xml.latest-id @latest_version_update.guid
  xml.download-url @latest_version_update.download_url
  xml.release-information-url version_guid_url(@latest_vesrion_update.guid)
end

The fixed version is

xml.instruct!

xml.tag! 'update-manifest' do
  xml.tag! 'latest-id', @latest_version_update.guid
  xml.tag! 'download-url', @latest_version_update.download_url
  xml.tag! 'release-information-url', version_guid_url(@latest_vesrion_update.guid)
end

Answer 1

xml.tag! 'latest-id', "latest ID with hiphen."
