After you determine the application's behavior and all its constituent modules, you can optimize the application's performance by dropping the code that validates data because you don't need to continuously validate the format of data that survived the test cycle.Dropping validation code is a common practice that isn't much different from removing debug information when you're ready to ship any Windows application.After creating an instance, you simply call the Read method of the class to read the document. Reading an XML file Getting Node Information The Name Property returns the name of the node with the namespace prefix, and the Local Name property returns the name of the node without the prefix. The Value property returns the value of a current node. So if you call the Move To Content method, it skips other types of nodes besides the content type nodes.

For example, if the supplied reader had Whitespace Handling. This constructor can handle strings returned from A networked XML document is comprised of chunks of data aggregated by using various World Wide Web Consortium (W3C) standard inclusion mechanisms and therefore contains nodes that come from different places.

None set, this validating reader also ignores white space. document type definition (DTD) entities are an example of this, but this is not limited to DTDs.

Xml Parser Context context = new Xml Parser Context(null, nsmgr, null, Xml Space. reader = new Xml Validating Reader(xml Frag, Xml Node Type. Has Attributes){ for (int i=0; i Option Strict Option Explicit Imports System Imports System. Xml Public Class Sample Public Shared Sub Main() Dim reader As Xml Validating Reader = Nothing Try ' Create the string to parse. Value) Next i ' Move the reader back to the node that owns the attribute. Move To Element() End If Finally If Not (reader Is Nothing) Then reader.

Element, context); //Read the attributes on the root element. Dim xml Frag As String = " " ' Create the Xml Namespace Manager. Close() End If End Try End Sub ' Main ' End class End Class ' Sample The Xml Validating Reader class is obsolete in . You can create a validating Xml Reader instance by using the Xml Reader Settings class and the Create method.

But the Xml Text Reader class doesn't do data validation. To gain more speed while parsing, XML readers don't provide for data validation.

To validate data, you need to use the Xml Validating Reader class. But in general, data validation against a Document Type Definition (DTD), XML Data Reduced (XDR), or schema is useful, particularly during the development cycle.

Element, context) ' Read the attributes on the root element.

NET Framework provides you with tools that are not only powerful but easy to use.

If it finds the document is not a valid XML schema, it generates the error telling the problem in the schema.

After an exception is thrown the state of the reader is not predictable.

But when you develop XML applications, some exceptions make data validation necessary every time a piece of code is called to action.
