Xml namespace is probably the most significant of these namespaces if only because it includes classes such as Xml Document, Xml Node Reader, Xml Reader, and Xml Reader Settings, which are critical in validating XML data.Xml Serializer config section handler is the optimum approach for dealing with configuration in . You basically start definining your configuration in an XML Schema, then use or another even more cool approach, and finally get Xml Serializer-ready classes for it." _ & "&ent;" Private Sub Form1_Load(By Val sender As System. Load Dim reader As Xml Text Reader = New Xml Text Reader(New String Reader(target)) While reader. Being well-formed requires the XML data to be syntactically correct; otherwise, the XML parser will raise an error. It conforms to the World Wide Web Consortium (W3C) XML schema standards and recommendations. NET Framework 2.0 classes support the W3C XML schema recommendation.XML data is valid when the elements and the content of the individual elements in the XML data conform to the declared data types specified in the schema or DTD. NET is handled primarily by the classes present in a handful of namespaces: System. The classes that are commonly employed to validate the XML document are Xml Reader, Xml Reader Settings, Xml Schema Set, and Xml Node Reader.You specify the validation settings as well as a Validation Event Handler method using the Xml Reader Settings object. I won't explain how to validate XML data using DTDs because those are not typically used outside legacy applications.You then perform the validation during the reading and parsing operations of the factory-created Xml Reader object. Validation is the process of enforcing rules on the XML content either through an XSD schema or a DTD or XDR schema.
NET Framework gave you some capable tools for validating XML data. NET Framework 2.0 augments the original capabilities significantly. NET 1.x's XML validation features, providing new classes and methods that are not only standards-compliant, but also easy to use. An XML file is usually validated for its conformance to a particular schema or a DTD. NET Intellisense or something (auto-completing Load Xml instead of just Load) - doh! The variable "xml" was a full file path to an xml FILE I was trying to load, and silly me, you have to use doc Xml. Load Xml() - the typo must have gotten in there from a poor use of VS. NET / C# problem, but again I thought I'd post something about it in case it helps someone else searching about this issue.... Xml Exception: The data at the root level is invalid.
