    @atest = @myschema.validate (@mytmp)

    haml :upload, :layout => false 
    end 

    post '/upload' do

    while blk = tmpfile.read(65536) 
     # read tempfile with nokogiri and validate against xsd schema 
     @mytmp = Nokogiri::XML(tmpfile) 
     open_schema 
     check_file

    "#{@mytmp}" # returns <?xml version="1.0"?> 
    #{}"@test = #{@test} @atest = #{@atest}" # @test = false 
    end 

end 

xml 파일을 명령 줄에서 xsd 스키마와 비교하여 유효성 검사를 시도하면 문제없이 작동합니다.

xmlreader.rb (Ruby 스크립트 비시나) 내가 용액 발견

require 'nokogiri' 

doc = Nokogiri::XML(File.open('my.xml')) 
schema = Nokogiri::XML::Schema(File.open('my.xsd')) 
y = schema.valid? (doc) #returns false if invalid and true if valid 
x = schema.validate (doc) #returns a listing of errors 
puts "valid? #{y} errors: #{x}"

:

post '/upload' do 
    unless params[:file] && 
     (tmpfile = params[:file][:tempfile]) && 
     (name = params[:file][:filename]) 
    @error = "No file selected" 
    return haml(:upload) 
    end 
    STDERR.puts "Uploading file, original name #{name.inspect}" 
    @mytmp = Nokogiri::XML(tmpfile.read) 
    open_schema 
    check_file 
end
