Validating xml against dtd dating site with email

A simple program can be written to transform the above to XML, and most models already have many online transformers from them to XML.
But it is rarely something that directly or powerfully improves the software.
In fact, the use of validation against DTDs and XML Schemas is counter-productive to creating good software in many different situations.
I am currently dealing with such a service: they tell you how to form the input, but then they return the response as a string. Said complex XML has no schema to validate against, so I have no idea what I am guaranteed to get back from the server, what is optional, or what types are possibly returned.
It is effectively useless, as it tells me nothing useful. because you don't want to write validators yourself, and if you do, it is very likely you aren't experienced in doing so, and when you need to change it to meet new requirements, you'll have an awful time.
Validation by DTD or XML Schema is often used for the sake of industry compliance or simply because developers think that to use XML you must formally validate it.helps knowing what the inputs and outputs for the web service are.Then there are the badly-formed web services: they tell you what they expect from you, but then return some nonsense.Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.Visit Stack Exchange Software Engineering Stack Exchange is a question and answer site for professionals, academics, and students working within the systems development life cycle.
