What do you want to do?

I’m pretty sure that running a small XPath snippet is the easiest way to do this.

Of course, you also can read the memoized results from REFCACHEDIR, but that structure is tied to a specific kramdown-rfc version and might change frequently (although it hasn’t for a while).  [I probably should write these out in CBOR and not in Ruby’s Marshal.dump…]

But XPath really is trivial, see below.

Grüße, Carsten


#!/usr/bin/env ruby
require 'rexml/document'

d = REXML::Document.new(ARGF)

REXML::XPath.each(d.root, "//svg:svg", {"svg" => "http://www.w3.org/2000/svg"}) do |x|
  puts x.to_s[0..200]
end
