Validate XML with xsd => no error when delete row in the xml file

Question

I want to validate xml file with an xsd. It's already work when i put an incorect type but it's doesn't work when i delete row in my xml document. How do this?

<Test>
    <TestNode1>1</TestNode1>
    <TestNode2>true</TestNode2>
    <TestNode3>true</TestNode3>
    <TestNode4>true</TestNode4>
    <TestNode5>true</TestNode5>
</Test>

<xs:element name="Test">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="TestNode1" type="xs:boolean"/>
      <xs:element name="TestNode2" type="xs:boolean"/>
      <xs:element name="TestNode3" type="xs:boolean"/>
      <xs:element name="TestNode4" type="xs:boolean"/> 
      <xs:element name="TestNode5" type="xs:boolean"/>     
    </xs:sequence>
  </xs:complexType>
</xs:element>

When i remove the row who contains testnode4 for exemple... and when i use this =>

XmlReaderSettings xmlSettings = new XmlReaderSettings();
xmlSettings.IgnoreWhitespace = true;
xmlSettings.Schemas = new System.Xml.Schema.XmlSchemaSet();
xmlSettings.Schemas.Add(null, xsdUri);
xmlSettings.ValidationType = ValidationType.Schema;
using (var xmlStream = File.OpenRead(xmlUri))
{
    var xmlFile = XmlReader.Create(xmlStream, xmlSettings);
    while (xmlFile.Read()) { }
}

It's work but i don't want this.I want to get error when row is missed.

Thanks.

As you can see here http://www.w3schools.com/schema/el_sequence.asp .

The sequence element specifies that the child elements must appear in a sequence. Each child element can occur from 0 to any number of times.

If you want your element to be present every time, you have to specify a minOccurs attribute.
