Ox adapter XML to object mapper not working with xml header specified

[tomkra]

Example XML:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<PACKAGE>
  <version>2</version>
  <empty_offers>1</empty_offers>
  <definictions>definictions.xml</definictions>
  <FILES>
    <file>13467_20230926_100629_001.xml</file>
  </FILES>
</PACKAGE>

Shale mapper:

require 'shale/adapter/ox'
Shale.xml_adapter = Shale::Adapter::Ox

module Asari::XmlParser
  class Cfg < Shale::Mapper
    attribute :version, Shale::Type::Integer
    attribute :empty_offers, Shale::Type::Integer
    attribute :definictions, Shale::Type::String

    xml do
      map_element 'version', to: :version
      map_element 'empty_offers', to: :empty_offers
      map_element 'definictions', to: :definictions
    end
  end
end

When the XML header <?xml version="1.0" encoding="utf-8" standalone="yes"?> is included in XML file, attributes are not mapped correctly:

# with XML header included
Asari::XmlParser::Cfg.from_xml(xml))
=> #<Asari::XmlParser::Cfg:0x00007f82971aa038 @version=nil, @empty_offers=nil, @definictions=nil>

# without XML header included
Asari::XmlParser::Cfg.from_xml(xml))
=> #<Asari::XmlParser::Cfg:0x00007f8299c22d10 @version=2, @empty_offers=1, @definictions="definictions.xml">

When I try for example Nokogiri adapter, everything works as expected with or without XML header. I've tried to specify root element, but It's not working either.

Am I doing something wrong? All examples are without XML header tag, but It's possible to generate XML document with XML header included, so I think It should work.

Thanks for pointing it out. The fix is ready on master.
