Validating xml file against schema

Specifically, after successful validation, schema defaults are applied, text values are converted to atomic values as necessary, and type information is associated with validated information items.

The result is a previously un-typed XML sub-tree in the Xml Document replaced with a typed sub-tree.

To validate an XML document, construct an Xml Reader Settings object that contains an XML schema definition language (XSD) schema with which to validate the XML document. For more information on validating XML documents with LINQ to XML, see How to: Validate Using XSD.

An individual schema or a set of schemas (as an Xml Schema Set) can be added to an Xml Schema Set by passing either one as a parameter to the Add method of Xml Schema Set.

Hello, I am trying to validate a xml file against a schema using SAX. This change is also visible using the online validator.

My problem is, that no error messages is thrown, even if I change the xml file to not match the schema. The result of the validation: The structure of the Xml Document is NOT valid. Xml Message: The element 'Catalogue Item Specification Update' in namespace 'urn:oasis:names:specification:ubl:schema:xsd: Catalogue Item Specification Update-2' has invalid child element 'UBLVersion ID2' in namespace 'urn:oasis:names:specification:ubl:schema:xsd: Common Basic Components-2'.

Recently I got a question from one of our customers: how do we validate XMLs against their XSD definition?

Note that when validating a document the target namespace of the document must match the target namespace of the schema in the schema set. CODE [XSDInference Examples#5](../Code Snippet/VS_Snippets_Data/XSDInference Examples#5)]The following is the schema that validates the example XML document.[!

CODE [XSDInference Examples#6](../Code Snippet/VS_Snippets_Data/XSDInference Examples#6)]In the code example that follows, the schema above is added to the Xml Schema Set Schemas property of the Xml Reader Settings object.

Process Schema Location; Xml Reader XMLvalidator = Xml Reader.

XML Schema definition language (XSD) schema validation is implemented using the validity constraints defined in the World Wide Web Consortium (W3C) XML Schema Recommendation. NET Framework supports the W3C XML Schema 2001 Recommendation.
