为什么XmlDocument Validate事件处理程序没有被击中？

Question

我有这样的代码：

// 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; 
    } 
} 

顶线我的XSD的：

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

任何想法？

Answer 1

我有一些代码验证xml使用这种结构。

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));

我不认为这是验证的正确方法;试试这个MSDN link。基本上，模式似乎与XmlReaderSettings相反。

XmlReaderSettings settings = new XmlReaderSettings(); 
settings.Schemas.Add(...); 
settings.ValidationType = ValidationType.Schema; 

XmlReader reader = XmlReader.Create(..., settings); 
XmlDocument document = new XmlDocument(); 
document.Load(reader); 

document.Validate(eventHandler);
