If you do not need data validation, the ability to resolve general entities, or support for default attributes, use Xml Text Reader.Write-only Sets the Xml Resolver used for resolving external DTD and schema location references.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.Xml Reader Settings o Settings = new Xml Reader Settings(); o Settings.However a validation event is not raised when the content has an undescore character in it.If the node is not a content node, the reader skips ahead to the next content node or end of file.It skips over nodes of the following type: Processing Instruction, Document Type, Comment, Whitespace, or Significant Whitespace.
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. For example, the reported node type may be different than the actual node type of the current node. Read State property to check whether a reader is in error state. After an exception is thrown the state of the reader is not predictable. Xml Validating Reader class is obsolete in dnprdnext.
