Xmlvalidatingreader xsd

(For more information about the Xml Reader, see NIB: Reading XML Data with Xml Text Reader.) The Read Xml method reads the contents of the XML stream or document and loads the Data Set with data.

It will also create the relational schema of the Data Set depending on the Xml Read Mode specified and whether or not a relational schema already exists.

To fill a Data Set with data from XML, use the Read Xml method of the Data Set object.

The following table describes the options for the Xml Read Mode argument. Examines the XML and chooses the most appropriate option in the following order: - If the XML is a Diff Gram, Diff Gram is used.- If the Data Set contains a schema or the XML contains an inline schema, Read Schema is used.- If the Data Set does not contain a schema and the XML does not contain an inline schema, Infer Schema is used.

If you know the format of the XML being read, for best performance it is recommended that you set an explicit Xml Read Mode, rather than accept the Auto default.

The Xml Schema Set is a cache where XML Schema definition language (XSD) schemas can be stored and validated. Xml version 1.0, XML schemas were loaded into an Xml Schema Collection class as a library of schemas. Xml version 2.0, the Xml Validating Reader and the Xml Schema Collection classes are obsolete, and have been replaced by the Create methods, and the Xml Schema Set class respectively.

The Xml Schema Set has been introduced to fix a number of issues including standards compatibility, performance, and the obsolete Microsoft XML-Data Reduced (XDR) schema format.

This section will discuss the support in the Services Framework for working with XML in these ways.

At the highest level, the classes used to manipulate XML in the Services Framework are included in the namespace collectively supports the W3C standards XML 1.0 and DTDs, XML namespaces ( XML schemas ( XPath expressions ( XSL transformations ( DOM Level 2 Core ( and SOAP 1.1. However, the Services Framework implementation includes better standards compliance and a simpler programming model (especially for streamed access) that should make life easier.

Allow Xml Attributes; // Set the validation settings. Validation Event Handler = On Validation Event Handler; // Create the Xml Reader object. Create(_xml File Path, settings); // Parse the file.

NET Data Set can be created from an XML stream or document. NET Framework you have great flexibility over what information is loaded from XML, and how the schema or relational structure of the Data Set is created.

If any tables in the inline schema already exist in the Data Set, an exception is thrown.
