The XmlSchemaPatternFacet type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | XmlSchemaPatternFacet | Initializes a new instance of the XmlSchemaPatternFacet class. |
| Name | Description | |
|---|---|---|
![]() ![]() | Annotation | Gets or sets the annotation property. (Inherited from XmlSchemaAnnotated.) |
![]() ![]() | Id | Gets or sets the string id. (Inherited from XmlSchemaAnnotated.) |
![]() ![]() | IsFixed | Gets or sets information that indicates that this facet is fixed. (Inherited from XmlSchemaFacet.) |
![]() ![]() | LineNumber | Gets or sets the line number in the file to which the schema element refers. (Inherited from XmlSchemaObject.) |
![]() ![]() | LinePosition | Gets or sets the line position in the file to which the schema element refers. (Inherited from XmlSchemaObject.) |
![]() ![]() | Namespaces | Gets or sets the XmlSerializerNamespaces to use with this schema object. (Inherited from XmlSchemaObject.) |
![]() ![]() | Parent | Gets or sets the parent of this XmlSchemaObject. (Inherited from XmlSchemaObject.) |
![]() ![]() | SourceUri | Gets or sets the source location for the file that loaded the schema. (Inherited from XmlSchemaObject.) |
![]() ![]() | UnhandledAttributes | Gets or sets the qualified attributes that do not belong to the current schema's target namespace. (Inherited from XmlSchemaAnnotated.) |
![]() ![]() | Value | Gets or sets the value attribute of the facet. (Inherited from XmlSchemaFacet.) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The following example shows the use of the XmlSchemaPatternFacet class.
#using <System.Xml.dll> using namespace System; using namespace System::Xml; using namespace System::Xml::Schema; ref class XMLSchemaExamples { private: static void ValidationCallbackOne(Object^ sender, ValidationEventArgs^ args) { Console::WriteLine(args->Message); } public: static void Main() { XmlSchema^ schema = gcnew XmlSchema(); // <xs:simpleType name="ZipCodeType"> XmlSchemaSimpleType^ ZipCodeType = gcnew XmlSchemaSimpleType(); ZipCodeType->Name = "ZipCodeType"; // <xs:restriction base="xs:string"> XmlSchemaSimpleTypeRestriction^ restriction = gcnew XmlSchemaSimpleTypeRestriction(); restriction->BaseTypeName = gcnew XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema"); // <xs:pattern value="[0-9]{5}(-[0-9]{4})?"/> XmlSchemaPatternFacet^ pattern = gcnew XmlSchemaPatternFacet(); pattern->Value = "[0-9]{5}(-[0-9]{4})?"; restriction->Facets->Add(pattern); ZipCodeType->Content = restriction; schema->Items->Add(ZipCodeType); // <xs:element name="Address"> XmlSchemaElement^ element = gcnew XmlSchemaElement(); element->Name = "Address"; // <xs:complexType> XmlSchemaComplexType^ complexType = gcnew XmlSchemaComplexType(); // <xs:attribute name="ZipCode" type="ZipCodeType"/> XmlSchemaAttribute^ ZipCodeAttribute = gcnew XmlSchemaAttribute(); ZipCodeAttribute->Name = "ZipCode"; ZipCodeAttribute->SchemaTypeName = gcnew XmlQualifiedName("ZipCodeType", ""); complexType->Attributes->Add(ZipCodeAttribute); element->SchemaType = complexType; schema->Items->Add(element); XmlSchemaSet^ schemaSet = gcnew XmlSchemaSet(); schemaSet->ValidationEventHandler += gcnew ValidationEventHandler(ValidationCallbackOne); schemaSet->Add(schema); schemaSet->Compile(); XmlSchema^ compiledSchema = nullptr; for each (XmlSchema^ schema1 in schemaSet->Schemas()) { compiledSchema = schema1; } XmlNamespaceManager^ nsmgr = gcnew XmlNamespaceManager(gcnew NameTable()); nsmgr->AddNamespace("xs", "http://www.w3.org/2001/XMLSchema"); compiledSchema->Write(Console::Out, nsmgr); } }; int main() { XMLSchemaExamples::Main(); return 0; }
The following XML file is generated for the preceding code example.
<?xml version="1.0" encoding="IBM437"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:simpleType name="ZipCodeType">
<xs:restriction base="xs:string">
<xs:pattern value="[0-9]{5}(-[0-9]{4})?"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="Address">
<xs:complexType>
<xs:attribute name="ZipCode" type="ZipCodeType"/>
</xs:complexType>
</xs:element>
</xs:schema>
