System.Xml.Schema.XmlSchemaObject Class

Assembly: System.Xml.dll
Namespace: System.Xml.Schema

Summary: Creates an empty schema.

C# Syntax:


        public abstract class XmlSchemaObject

Example

The following example displays each schema object.

using System;
using System.Xml;
using System.Xml.Schema;
using System.IO;
using System.Reflection;

public class ValidXSD {
    public static int Main() {
        
        string xsd = "example.xsd";

        FileStream fs;
        XmlSchema schema;
        try {
            fs = new FileStream(xsd, FileMode.Open);
            schema = XmlSchema.Read(fs, new ValidationEventHandler(ShowCompileError));

            schema.Compile(new ValidationEventHandler(ShowCompileError));
            if (schema.IsCompiled) {
                DisplayObjects(schema);
            }
            return 0;
        } catch (XmlSchemaException e) {
            Console.WriteLine("LineNumber = {0}", e.LineNumber);
            Console.WriteLine("LinePosition = {0}", e.LinePosition);
            Console.WriteLine("Message = {0}", e.Message);
            Console.WriteLine("Source = {0}", e.Source);
            return -1;
        }
        catch (Exception e) {
            Console.WriteLine(e);
            return -1;
        }
    }
    
    public static void DisplayObjects(object o) {
        DisplayObjects(o, "");
    }
    public static void DisplayObjects(object o, string indent) {
        Console.WriteLine("{0}{1}", indent, o);

        foreach (PropertyInfo property in o.GetType().GetProperties()) {
            if (property.PropertyType.FullName == "System.Xml.Schema.XmlSchemaObjectCollection") {
            
                XmlSchemaObjectCollection childObjectCollection = (XmlSchemaObjectCollection) property.GetValue(o, null);
                
                foreach (XmlSchemaObject schemaObject in childObjectCollection) {
                    DisplayObjects(schemaObject, indent + "\t");
                }
            }
        }
    }
    public static void ShowCompileError(object sender, ValidationEventArgs e) {
        Console.WriteLine("Validation Error: {0}", e.Message);
    }
}

The example uses the example.xsd file as input.

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:group name="testGroup">
  <xs:choice>
    <xs:any namespace="##any"/>
  </xs:choice>
  </xs:group>
  <xs:element name="myElement" >
  <xs:complexType>
    <xs:choice maxOccurs="unbounded">
      <xs:group ref="testGroup" />
    </xs:choice>
  </xs:complexType>
  </xs:element>
</xs:schema>
