【问题描述】:
EDIT2:问题似乎出在我的 xsd 上。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示例。同样的问题,无论我比较什么 xml 和 xsd,它都没有发现错误。即使我使用随机不同的 xsd,它也会一直说一切都很好。
我发现了很多不使用 LINQ 的例子,但是你会如何使用 LINQ 呢?
我使用 Google 查找了一个示例,但它似乎在大多数情况下都跳过了验证每个 XML 的验证。 (它曾经进入它,拒绝该文件,但我无法重现它。)
有没有更好的方法,或者它是否有理由跳过验证?
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;
}
