XmlSchemaFractionDigitsFacet Class
.NET Framework 3.0
Specifies a restriction on the number of digits that can be entered for the fraction value of a simpleType element. The value of fractionDigits must be a positive integer. Represents the World Wide Web Consortium (W3C) fractionDigits facet.
Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)
Assembly: System.Xml (in system.xml.dll)
The following example shows the use of the XmlSchemaFractionDigitsFacet class.
using System; using System.Xml; using System.Xml.Schema; class XMLSchemaExamples { public static void Main() { XmlSchema schema = new XmlSchema(); // <xs:simpleType name="RatingType"> XmlSchemaSimpleType RatingType = new XmlSchemaSimpleType(); RatingType.Name = "RatingType"; // <xs:restriction base="xs:number"> XmlSchemaSimpleTypeRestriction restriction = new XmlSchemaSimpleTypeRestriction(); restriction.BaseTypeName = new XmlQualifiedName("decimal", "http://www.w3.org/2001/XMLSchema"); // <xs:totalDigits value="2"/> XmlSchemaTotalDigitsFacet totalDigits = new XmlSchemaTotalDigitsFacet(); totalDigits.Value = "2"; restriction.Facets.Add(totalDigits); // <xs:fractionDigits value="1"/> XmlSchemaFractionDigitsFacet fractionDigits = new XmlSchemaFractionDigitsFacet(); fractionDigits.Value = "1"; restriction.Facets.Add(fractionDigits); RatingType.Content = restriction; schema.Items.Add(RatingType); // <xs:element name="movie"> XmlSchemaElement element = new XmlSchemaElement(); element.Name = "movie"; // <xs:complexType> XmlSchemaComplexType complexType = new XmlSchemaComplexType(); // <xs:attribute name="rating" type="RatingType"/> XmlSchemaAttribute ratingAttribute = new XmlSchemaAttribute(); ratingAttribute.Name = "rating"; ratingAttribute.SchemaTypeName = new XmlQualifiedName("RatingType", ""); complexType.Attributes.Add(ratingAttribute); element.SchemaType = complexType; schema.Items.Add(element); XmlSchemaSet schemaSet = new XmlSchemaSet(); schemaSet.ValidationEventHandler += new ValidationEventHandler(ValidationCallbackOne); schemaSet.Add(schema); schemaSet.Compile(); XmlSchema compiledSchema = null; foreach (XmlSchema schema1 in schemaSet.Schemas()) { compiledSchema = schema1; } XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable()); nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema"); compiledSchema.Write(Console.Out, nsmgr); } public static void ValidationCallbackOne(object sender, ValidationEventArgs args) { Console.WriteLine(args.Message); } }
The following XML file is generated for the preceding code example.
