Esempio

Nell'esempio seguente viene creato l'elemento any .

using System;
using System.Xml;
using System.Xml.Schema;

class XMLSchemaExamples
{
    public static void Main()
    {

        XmlSchema schema = new XmlSchema();

        // <element name='htmlText'>
        XmlSchemaElement xeHtmlText = new XmlSchemaElement();
        xeHtmlText.Name = "htmlText";

        XmlSchemaComplexType ct = new XmlSchemaComplexType();

        XmlSchemaSequence sequence = new XmlSchemaSequence();

        // <any namespace='http://www.w3.org/1999/xhtml'
        //    minOccurs='1' maxOccurs='unbounded'
        //    processContents='lax'/>
        XmlSchemaAny any = new XmlSchemaAny();
        any.MinOccurs = 1;
        any.MaxOccursString = "unbounded";
        any.Namespace = "http://www.w3.org/1999/xhtml";
        any.ProcessContents = XmlSchemaContentProcessing.Lax;
        sequence.Items.Add(any);

        ct.Particle = sequence;
        xeHtmlText.SchemaType = ct;

        schema.Items.Add(xeHtmlText);

        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");
        schema.Write(Console.Out, nsmgr);
    }

    public static void ValidationCallbackOne(object sender, ValidationEventArgs args)
    {
        Console.WriteLine(args.Message);
    }
}

Class XMLSchemaExamples

    Public Shared Sub Main()

        Dim schema As New XmlSchema()

        ' <element name='htmlText'>
        Dim xeHtmlText As New XmlSchemaElement()
        xeHtmlText.Name = "htmlText"

        Dim ct As New XmlSchemaComplexType()

        Dim sequence As New XmlSchemaSequence()

        ' <any namespace='http://www.w3.org/1999/xhtml'
        '    minOccurs='1' maxOccurs='unbounded'
        '    processContents='lax'/>
        Dim any As New XmlSchemaAny()
        any.MinOccurs = 1
        any.MaxOccursString = "unbounded"
        any.Namespace = "http://www.w3.org/1999/xhtml"
        any.ProcessContents = XmlSchemaContentProcessing.Lax
        sequence.Items.Add(any)

        ct.Particle = sequence
        xeHtmlText.SchemaType = ct

        schema.Items.Add(xeHtmlText)

        Dim schemaSet As New XmlSchemaSet()
        AddHandler schemaSet.ValidationEventHandler, AddressOf ValidationCallbackOne

        schemaSet.Add(schema)
        schemaSet.Compile()

        Dim compiledSchema As XmlSchema = Nothing

        For Each schema1 As XmlSchema In schemaSet.Schemas()
            compiledSchema = schema1
        Next

        Dim nsmgr As New XmlNamespaceManager(New NameTable())
        nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema")
        compiledSchema.Write(Console.Out, nsmgr)
    End Sub


    Public Shared Sub ValidationCallbackOne(ByVal sender As Object, ByVal args As ValidationEventArgs)
        Console.WriteLine(args.Message)
    End Sub
End Class

Il file XML seguente viene generato per l'esempio di codice precedente.

<?xml version="1.0" encoding="IBM437"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name='htmlText'>
      <xs:complexType>
       <xs:sequence>
         <xs:any namespace='http://www.w3.org/1999/xhtml'
              minOccurs='1' maxOccurs='unbounded'
              processContents='lax'/>
       </xs:sequence>
      </xs:complexType>
    </xs:element>
</xs:schema>
