The sequence of steps to validate an XML document is given as follows: This article explained about the XML document, XSD schema, and how to validate XML document against XSD schema using Microsoft .

The previous article in this series discussed the DOM API for XML data access in the . It models an XML document as a tree of nodes kept in memory while a client is using the document.

The top part of Figure 1 shows how the DOM parser produces a tree of nodes.

The client access methods allow forward and backward movement, much like the client-side, static cursor in ADO data access on the Microsoft platform.

Another limitation is that the client must implement all interface methods, and the methods are always called by the parser, regardless of whether the client is interested in them.

Microsoft recognized the state of parsers in the XML world and designed an efficient XML API that was also simple to use.

Microsoft borrowed a concept from the "firehose" cursor used in ADO.

The class has properties and methods that return the values and move the cursor across the document content.

I modified the code to use the Xml Reader Settings() class, then added the schemas to it's Schema collection: var settings = new Xml Reader Settings(); // Code removed settings. Add(" @"C:\tmp\textxml\Formdom.xsd"); // Code removed var validating = Xml Reader. This type of API is called a "push model" because the document information is pushed from the parser to the client.The middle part of Figure 1 illustrates the SAX approach to parsing.You can access value, node type, and namespace information quickly and easily using the properties shown in the following list. I am working with a fairly complex third-party XSD format - XSDs refer to types in another XSD which refers to types in yet another XSD.Xml Validating Reader implements the Xml Reader class and provides support for data validation. Schemas property to have the reader validate using schema files cached in an Xml Schema Collection. Validation Type property specifies what type of validation the reader should perform. To read XML data from an Xml Node, use Xml Node Reader. If you do not need data validation, the ability to resolve general entities, or support for default attributes, use Xml Text Reader.XSD schema for the above XML document, address.xsd, can be given as follows: The Validation Event Handler event is used to define an event handler for receiving the notification about XSD schema validation errors.The validation errors and warnings are reported through the Validation Event Handler call-back function.The cost of this type of capability is the resource requirements needed to keep each node in memory. The SAX API was one of the first attempts in the XML community to solve the problem of parsing large XML documents.This can present a real problem when document sizes become too large to fit in memory in an efficient manner. The SAX parser uses a streaming model that moves through a document piece by piece and doesn't retain a copy of the nodes once they are traversed.
