As part of the validation process, software called a validating parser is used to examine the subject XML, and compare it to these rules.The rules may be specified to the parser, either as a reference to a file (a URI) or by passing the rules as part of the XML documentreferred to as inline.The Validation Error method is called if the document being read is found to be invalid or an error occurs (for example, the document cannot be found).Failure to register a method with Validation Event Handler causes an exception (Xml Exception) to be thrown when the XML document is found to be invalid or missing.In this example, we demonstrate how to activate such validation.The illustration validates an XML document that the user chooses, either or catelog1against the XML Schema document There are two different measures of correctness of an XML document: well-formed and valid.A well-formed XML document adheres to a few basic rules: A valid XML document is, first of all, a well-formed XML document.
Somehow, though, I can't seem to validate it automatically in C# without specifying the schema to validate against like so: Xml Document asset = new Xml Document(); Xml Text Reader schema Reader = new Xml Text Reader("relative Schema Path"); Xml Schema schema = Xml Schema. I try using 7 several methods for validate XML using XSD, but all fails for me. I try using 7 several methods for validate XML using XSD, but all fails for me.It assigns a new Xml Schema Set object to variable schemas, and calls this object's Add method to add a schema to the collection.The Add method receives as arguments a namespace URI that identifies the schema ( and the name and location of the schema file (in the current directory).However, when the user selects the XML document catalog1.xml, validation fails for the book element in the lines containing more than one title element.When the program encounters the invalid node, the method Validation Error is called that displays a message explaining why validation failed. An object of the class Xml Schema Set stores a collection of schemas that an Xml Reader can be validated against.
