私のコードでは、XML リクエストを作成しています。ただし、次の単純なフラグメントではエラーが発生します。
def create_gateways_request
@request_xml = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml|
xml.gateways(:ua => "#{@plugin_name} #{@version}") {
xml.merchant {
xml.account MSP['merchant']['account_id']
xml.site_id MSP['merchant']['site_id']
xml.site_secure_code MSP['merchant']['site_code']
}
xml.customer {
xml.country @customer[:country]
}
}
end
@request_xml.to_xml
end
エラー:

ルートノードは<gateways>
ですよね?
ここで何が間違っていますか?
