EDIT2:问题似乎是我的xsd。它几乎验证了每一个XML。我不能在这里发布XSD。为什么每个XML都对XSD有效?
编辑:在here的答案中找到了类似的例子。同样的问题,无论xml和xsd我比较,它都没有发现错误。即使我使用随机不同的xsd,它仍然说它一切都很好。
我发现很多例子都是在没有LINQ的情况下做的,但是你如何使用LINQ呢?
我使用Google查找示例,但似乎大多数情况下都会跳过验证来验证每个XML。 (它曾经进入它,拒绝该文件,但我无法重现它。)
是否有更好的方法可以做到这一点,还是有理由跳过验证?
public String ValidateXml2(String xml, String xsd)
{
String Message = String.Empty;
var ms = new MemoryStream(Encoding.Default.GetBytes(xml));
// Create the XML document to validate against.
XDocument xDoc = XDocument.Load(ms, LoadOptions.PreserveWhitespace);
XmlSchemaSet schema = new XmlSchemaSet();
bool isError = new bool(); // Defaults to false.
int countError = 1; // Counts the number of errors have generated.
Stream xsdMemoryStream = new MemoryStream(Encoding.Default.GetBytes(xsd));
// Add the schema file you want to validate against.
schema.Add(XmlSchema.Read
(xsdMemoryStream,
new ValidationEventHandler((sender, args) =>
{
Message = args.Exception.Message;
})
));
// Call validate and use a LAMBDA Expression as extended method!
// Don't you love .NET 3.5 and LINQ...
xDoc.Validate(schema, (sender, e) =>
{
switch (e.Severity)
{
case XmlSeverityType.Error:
Console.WriteLine("Error {0} generated.", countError);
break;
case XmlSeverityType.Warning:
Console.WriteLine("Warning {0} generated.", countError);
break;
}
Console.WriteLine(sender.GetType().Name);
Console.WriteLine("\r\n{0}\r\nType {1}\r\n", e.Message,
e.Severity.ToString());
Console.WriteLine("-".PadRight(110, '-'));
countError++;
isError = true; // If error fires, flag it to handle once call is complete.
}
, true); // True tells the validate call to populate the post-schema-validation
// which you will need later, if you want to dive a littel deeper...
if (isError == true) // Error has been flagged. Lets see the errors generated.
Console.WriteLine("You my friend have {0} error(s), now what?", countError);
else
Console.WriteLine("You rock! No errors...");
Console.Write("\r\n\r\nPress Enter to End");
Console.ReadKey();
return Message;
}

显然使用LINQ to XML,您必须让模式targetNamespace与您正在检查的xml的名称空间匹配,因为validate方法会查看一个模式集合,以验证文档名称空间。如果找不到,则验证文件。
