Do I need to write my own validator for xml validation against xsd schema?

[thePrado]

I'm trying to support my users in creating an xml based on an xsd (xml schema).So I show possible elements and the user can add it to an xml.However, i have problems to determine the possible elements or to validate that what the user adds is correct. How do I check complex elements?Let's say we have a sequence element. How am I going to check that the user adds an element at the right place? Let's say we have a choice element. How am I going to check that an element from the other particle has been added already?I can validate the xml against the schema in c# but the errors it returns can (maybe) be showed to the user but I can't use them in my code since the format is inappropriate for that and it just doesn't return enough details.Do I need to write my own validator (and implement all the w3c specs)??Thanks!
