How Do I...Infer an XML Schema?

This sample illustrates how to infer an XML schema from a given XML document by using the XmlSchemaInference class. An XmlSchemaInference object is used to infer an XML schema from a particular XML document, and then adds the inferred schema to an XmlSchemaSet object. The inferred schema is further refined by using schemas inferred from additional XML documents.

The following code creates the XmlSchemaInference and XmlSchemaSet objects.

XmlSchemaInference infer = new XmlSchemaInference(); XmlSchemaSet sc = new XmlSchemaSet(); Dim infer As New XmlSchemaInference() Dim sc As New XmlSchemaSet() XmlSchemaInference^ infer = gcnew XmlSchemaInference; XmlSchemaSet^ sc = gcnew XmlSchemaSet();

The following code infers an XML schema from an XML document.

sc = infer.InferSchema(new XmlTextReader("sample.xml")); sc = infer.InferSchema(new XmlTextReader("sample.xml")) sc = infer->InferSchema(gcnew XmlTextReader(L"sample.xml"));
