A valid document is one which, in addition to being well-formed, adheres to the rules laid out in a document type definition (DTD) or XML Schema.

By imposing some structure on an XML document, a DTD makes it possible for documents to conform to some standard rules, and for applications to avoid nasty surprises in the form of incompatible or invalid data.

Here, I need to first initialize a plain-vanilla Xml Text Reader object, and then pass this object as a parameter to the new Xml Validating Reader object, as shown below:[code][/code]You can set the “Validation Type” property of the Xml Validating Reader object to any one of the following: Validation Type. Auto – search for a file automatically; if available, carry out validation Validation Type.

DTD – perform validation using a DTDValidation Type.

In such situations, you’ll also need to know how you can use a DTD to validate an XML document instance.

In case you don’t remember what it looked like, here it is again:[code] attribute.

In such a scenario, it makes sense to use the Xml Node Reader object to read the contents of the node because of its speed and efficient performance. Take a look at an example that uses the Xml Node Reader object.[code] collection is an Xml Node object that can easily be used to create an instance of the Xml Node Reader object, the object that I’m interested in here.

Since there will be multiple nodes resulting from this process, it make sense to place the corresponding code in a separate function which can be invoked repeatedly; hence the Read Xml Node() function in the example above.

And the next example does just that, using the ever-popular “try-catch” mechanism to trap any errors that might arise.

Take a look:[code]Notice how the script take note of the absence of the XML file and displays a polite little message informing the user about the error.
