Nokogiri XSD validation issues

Hi All,
I am using nokogiri gem(1.4.1) for xsd validation, it works well in my
local machine and doesn’t in my server, it didn’t validate some of the
xml
tags can anybody help, below is my code.

          inut_xml=request.raw_post
           errors =[]

xsd =
Nokogiri::XML::Schema(File.read("#{Rails.root}/public/dwp-integration-resource.xsd"))
doc = Nokogiri::XML(input_xml)
xsd.validate(doc).each do |error|
errors << error.message
end

regards,
Loganathan
