Add a dtd using nokogiri builder

I am using nokogiri to generate svg pictures. I would like to add the correct xml preamble and svg DTD declaration to get something like:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> 
<svg>
...

With builder I could use instruct! and declare! but I want to stick with nokogiri because I use it for other purpose in my project and I want to stay low on requirements. Do you have some ideas ?

Thanks

Solution

  • You can now (don't know from which version) use Node#create_internal_subset to create the DTD node. For more info see: https://nokogiri.org/rdoc/Nokogiri/XML/Builder.html

    And scroll down to the "Document Types" section for an example.
