Is XSD validation with substitution groups supported?

[Lars Vonk]

Hi,

I am trying to validate an xml file against an XSD that makes use of substitution groups but can't get it to work. It keeps failing on the first substitution it finds and reports that the element is not expected. Since that is a substitutiongroup I suspect it has something to do with it, so my question is if this is supposed to work?

Ruby code:

require 'nokogiri'
xsd = File.open('./xbrl-instance-2003-12-31.xsd')
schema = Nokogiri::XML::Schema(xsd)
xml_document = File.open('./VB-01_bd-rpt-ob-aangifte-2020.xbrl')
doc = Nokogiri::XML(xml_document) do |config|
   config.strict.nonet
   config.noblanks
end
# puts doc.to_xml(indent: 2)
result = schema.validate(doc)
puts result

I attached the relevant files, put xbrl-instance-2003-12-31.xsd in the same directory as xbrl-linkbase-2003-12-31.xsd, xl-2003-12-31.xsd and xlink-2003-12-31.xsd

We are using nokogiri 1.10.9 and ruby 2.6.5

Thanks in advance,

Lars
