xml builder in ruby- remove namespace etc

# xmlObject = setattribute_value(node,'key',"AUTI")
 def setattribute_value(node, attributename, valueto_assign)
  node.attributes[attributename].value = valueto_assign 
end




remove namespace from xml:
# xmlObject = get_xml_object("../Files/Product.xml") 
def get_xml_object(path)
  @file = File.read(path)
  xmlObj = Nokogiri::XML(@file, nil, 'utf-8')
  @get_namespaces = xml_obj.namespaces
  xmlObj.remove_namespaces!
  xmlObj 
end


in xml file:
<?xml version="1.0" encoding="utf-8"?>
 <order xmlns="http://testing.pic/party/export">


xmlns is the namespace..
