可以在运行时使用代码针对 xsd 验证 xml 吗?

问题描述

我有在运行时读入的 xml 文件，是否可以在运行时针对 xsd 文件验证 xml?使用c#

I have xml files that I read in at runtime, is is possible to validate the xml against an xsd file at runtime? using c#

推荐答案

试试这个:

public void ValidateXmlDocument(
    XmlReader documentToValidate, string schemaPath)
{
    XmlSchema schema;
    using (var schemaReader = XmlReader.Create(schemaPath))
    {
        schema = XmlSchema.Read(schemaReader, ValidationEventHandler);
    }

    var schemas = new XmlSchemaSet();
    schemas.Add(schema);

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

    using (var validationReader = XmlReader.Create(documentToValidate, settings))
    {
        while (validationReader.Read())
        {
        }
    }
}

private static void ValidationEventHandler(
    object sender, ValidationEventArgs args)
{
    if (args.Severity == XmlSeverityType.Error)
    {
        throw args.Exception;
    }

    Debug.WriteLine(args.Message);
}
