Xmlvalidatingreader schematype property

It is fait accompli that almost every programmer devotes about 50 to 70 percent of his time in determining whether the data he/she is dealing with, is in the right format or not.Thus, the mainstay of XML Schema is that it grants the programmer the liberty to write the rules of data validity and thereafter, he can conveniently leave it to the XML Validator to verify whether the data satisfies these conditions or not.

Since we are not using any name, a value of null is supplied for the namespace. Moreover, the event Validation Event Handler is initialized to a function abc, which is called each time an error occurs.

The namespace only comes into play whenever the owner of a certain tag is to be ascertained. Thus, while reading the file, the Read function will apply the validation rules contained in the file b.xsd, and in the event of an error, it will call the function abc.

You can then react to the error in any way you see fit. First we will add an XDR (XM- Data Reduced) schema namespace to our namespace.

This collection holds pre-loaded XSD and XDR schemas.

The other feature is the validation of an xml file with a schema. Therefore, one has to learn two diverse syntaxes; one for XML and the other for DTDs. The major flaw with the DTD world surfaces during the creation of new data types.

For instance, if there is an xml file, such as an invoice representing a purchase order, then this invoice must have a certain format or syntax, or else it must be bound by a set of rules. For instance, it is elementary to create a data type that restricts the value of an element to 1000.

This gives an easier and more intuitive programming model.

Another advantage to this is that a pull model can be selective about the data that is sent to the application: if you don't want all of the data, then you don't need to process it.

The Add function is used to add the validation to the Schemas property, since it is a collection object.

In the Add function, the first parameter is the namespace URI of the schema.

It could be lodging on some other site on the net and could have been created by some Standards Body.
