Validate XML response against WSDL using Ruby Savon

问题

I am using Ruby/Cucumber/Savon to automate Soap webservice. I need to validate the response against the wsdl file. Savon docs don't mention validating XML response anywhere. Does anyone know a good solution to doing this?

Thanks, Harv Gill

The excellent Nokogiri library supports XML schema (XSD) validation which is used for SOAP messages (i.e. the "Types" section of the WSDL should contain a reference or inline XSD).

xsd = Nokogiri::XML::Schema(File.read(SCHEMA_FILE))
doc = Nokogiri::XML(File.read(XML_FILE))

xsd.validate(doc).each do |error|
  puts error.message
end

I've made a gem to simplify this process. It should extract all schemas from the WSDL and import any if needed. Let me know if it doesn't work for you.

require 'wsdl_validator'
wsld = WsdlValidator.new('path_to_wsdl')
# xml can be String, Nokogiri::XML::Document
wsdl.validate xml

This will return true if valid or raise an exception with the error message if it's not.

You can get the XML from a Savon response and pass by the following

wsdl = 'path_to_wsdl'
client = Savon::Client.new(wsdl: wsdl)  
response = client.call(:operation, message: { element: 'value' })
WsdlValidator.new(wsdl).validate response.xml
