Extensions Class
This class contains the LINQ to XML extension methods for XSD validation.
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
| Name | Description | |
|---|---|---|
![]() ![]() | GetSchemaInfo(XAttribute) | Gets the post-schema-validation infoset (PSVI) of a validated attribute. |
![]() ![]() | GetSchemaInfo(XElement) | Gets the post-schema-validation infoset (PSVI) of a validated element. |
![]() ![]() | Validate(XDocument, XmlSchemaSet, ValidationEventHandler) | This method validates that an XDocument conforms to an XSD in an XmlSchemaSet. |
![]() ![]() | Validate(XAttribute, XmlSchemaObject, XmlSchemaSet, ValidationEventHandler) | This method validates that an XAttribute conforms to a specified XmlSchemaObject and an XmlSchemaSet. |
![]() ![]() | Validate(XDocument, XmlSchemaSet, ValidationEventHandler, Boolean) | Validates that an XDocument conforms to an XSD in an XmlSchemaSet, optionally populating the XML tree with the post-schema-validation infoset (PSVI). |
![]() ![]() | Validate(XElement, XmlSchemaObject, XmlSchemaSet, ValidationEventHandler) | This method validates that an XElement sub-tree conforms to a specified XmlSchemaObject and an XmlSchemaSet. |
![]() ![]() | Validate(XAttribute, XmlSchemaObject, XmlSchemaSet, ValidationEventHandler, Boolean) | Validates that an XAttribute conforms to a specified XmlSchemaObject and an XmlSchemaSet, optionally populating the XML tree with the post-schema-validation infoset (PSVI). |
![]() ![]() | Validate(XElement, XmlSchemaObject, XmlSchemaSet, ValidationEventHandler, Boolean) | Validates that an XElement sub-tree conforms to a specified XmlSchemaObject and an XmlSchemaSet, optionally populating the XML tree with the post-schema-validation infoset (PSVI). |
This class also contains methods to get the post-schema-validation infoset (PSVI) of a validated XML node.
When you validate an XDocument, XElement, or XAttribute, you can also optionally populate the XML tree with the post-schema-validation infoset. PSVI information is added as an annotation of type System.Xml.Schema::XmlSchemaInfo.
The XSD in Sample XSD File: Customers and Orders contains a schema that can be used to validate the XML document in Sample XML File: Customers and Orders (LINQ to XML). The following example loads the schema and the document, validates the document, changes the document so that the xs:key and xs:keyref relationship is not valid, and then attempts to validate again.
This example produces the following output:
Validating custOrd custOrd validated Validating custOrd The key sequence 'AAAAA' in Keyref fails to refer to some key. custOrd did not validate
