System.Xml.Schema.XmlSchemaRedefine Class

Summary

Allows simple and complex types, groups, and attribute groups from external schema files to be redefined in the current schema. This class provides versioning for the schema elements. Represents the World Wide Web Consortium (W3C) redefine element.

C# Syntax:

public class XmlSchemaRedefine : XmlSchemaExternal

This class does the following:

The redefine element requires that the external elements exist in the same target namespace as the redefining schema. Schemas without a namespace can also be redefined using the redefine element, in which case the redefined components become part of the target namespace of the schema.

The definitions within the redefine element itself must use their current definitions as their base type definition. Attribute group definitions and model group definitions must include one and only one reference to themselves. Note that not all the definitions of the redefined schema document must be redefined.

Redefining elements may cause unexpected results, such as ill-formed definitions, on other type definitions that are based on the redefined definitions.

This provides a mechanism for versioning of schema types.

Summary

Gets the XmlSchemaObjectTable, for all groups in the schema, which holds the post-compilation value of the Groups property.

C# Syntax:

public XmlSchemaObjectTable Groups {get;}

Return to top

Inherited
See base class member description: System.Xml.Schema.XmlSchemaExternal.Id

Summary

Gets or sets the string id.

C# Syntax:

public string Id {get; set;}

Return to top

Summary

Gets the collection of the following classes: XmlSchemaAnnotation, XmlSchemaAttributeGroup, XmlSchemaComplexType, XmlSchemaSimpleType, and XmlSchemaGroup.

C# Syntax:

public XmlSchemaObjectCollection Items {get;}

Return to top

Inherited
See base class member description: System.Xml.Schema.XmlSchemaObject.LineNumber

Summary

Gets or sets the line number in the file to which the schema element refers.

C# Syntax:

public int LineNumber {get; set;}

LineNumber is used to store the line number when a schema is read from a file. This is reported through XmlSchemaException for error handling.

Inherited
See base class member description: System.Xml.Schema.XmlSchemaObject.LinePosition

Summary

Gets or sets the line position in the file to which the schema element refers.

C# Syntax:

public int LinePosition {get; set;}

This is used to store the line position when a schema is read from a file. This is reported through XmlSchemaException for error handling.

Summary

Gets or sets the XmlSchema for the referenced schema.

C# Syntax:

public XmlSchema Schema {get; set;}

Inherited
See base class member description: System.Xml.Schema.XmlSchemaExternal.SchemaLocation

Summary

Gets or sets the URI location for the schema, which tells the schema processor where the schema physically resides.

C# Syntax:

public string SchemaLocation {get; set;}

Imported schemas that do not have this attribute allow the imported schema's namespace to be determined by the XML document that is an instance of the containing schema or the application that is processing the schema.

Included schemas use this attribute as the URI reference to the location of a schema document that should be included in the target namespace of the containing schema.
