使用 XSD 架构进行 Xml 验证

以下代码帮助我使用 XSD 架构验证 XML 文件。

XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas.Add(null, xsdFilePath);
settings.ValidationType = ValidationType.Schema;
settings.ValidationEventHandler += new System.Xml.Schema.ValidationEventHandler(settings_ValidationEventHandler);
XmlDocument document = new XmlDocument();
document.Load(xmlFilePath);
XmlReader rdr = XmlReader.Create(new StringReader(document.InnerXml), settings);

while (rdr.Read())
{

}
isValid = true;

ValidationEventHandler 还告诉我错误是什么，但没有告诉我它们位于“哪里”或“哪一行”。有什么方法可以获取 XML 验证失败的行号吗？

这不正是你所追求的吗？

创建一个XmlReaderSettings对象并通过该对象启用警告。

不幸的是，似乎没有办法通过你自己的XmlReaderSettings反对XmlDocument.Validate().
相反，您可以使用验证XmlReader and an XmlNodeReader验证现有的XmlDocument（用一个XmlNodeReader with StringReader而不是一个XmlDocument)

XmlDocument x = new XmlDocument();
x.LoadXml(XmlSource);

XmlReaderSettings settings = new XmlReaderSettings();
settings.CloseInput = true;     
settings.ValidationEventHandler += Handler;

settings.ValidationType = ValidationType.Schema;
settings.Schemas.Add(null, ExtendedTreeViewSchema);
settings.ValidationFlags =
     XmlSchemaValidationFlags.ReportValidationWarnings |
XmlSchemaValidationFlags.ProcessIdentityConstraints |
XmlSchemaValidationFlags.ProcessInlineSchema |
XmlSchemaValidationFlags.ProcessSchemaLocation ;

StringReader r = new StringReader(XmlSource);

using (XmlReader validatingReader = XmlReader.Create(r, settings)) {
        while (validatingReader.Read()) { /* just loop through document */ }
}

和处理程序：

private static void Handler(object sender, ValidationEventArgs e)
{
        if (e.Severity == XmlSeverityType.Error || e.Severity == XmlSeverityType.Warning)
          System.Diagnostics.Trace.WriteLine(
            String.Format("Line: {0}, Position: {1} \"{2}\"",
                e.Exception.LineNumber, e.Exception.LinePosition, e.Exception.Message));
}
