为什么XmlDocument的验证事件处理程序没有得到打？ [英] Why is the XmlDocument Validate event handler not getting hit?

问题描述

我有这个code：

  // Load the document
  XmlDocument xmlDocument = new XmlDocument();

  // use the stream and have it close when it is finished
  using ( argInputStream )
  {
    xmlDocument.Load( argInputStream );
    xmlDocument.Schemas.Add( XmlSchema.Read( argSchemaStream, null ) );
    xmlDocument.Validate( ValidationEventHandler );
  }

// this is not getting hit
void ValidationEventHandler( object sender, ValidationEventArgs e )
{
  switch ( e.Severity )
  {
    case XmlSeverityType.Error:
      Console.WriteLine( "Error: {0}", e.Message );
      break;
    case XmlSeverityType.Warning:
      Console.WriteLine( "Warning {0}", e.Message );
      break;
  }
}

我的XSD的第一行：

top line of my XSD:

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" 
xmlns:xs="http://www.w3.org/2001/XMLSchema">

任何想法？

推荐答案

我有一些code。使用这种结构验证XML。

I've got some code validating xml using this construction.

var schemaReader = new XmlTextReader(argSchemaStream);
var schema = new XmlSchemaSet();
schema.Add(null, schemaReader);

var settings = new XmlReaderSettings();
settings.ValidationType = ValidationType.Schema;
settings.Schemas.Add(schema);
settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
settings.ValidationEventHandler += new ValidationEventHandler(ValidationEventHandler);

var doc = new XmlDocument();
doc.Load(XmlReader.Create(argInputStream, settings));
