我可以在加载xml文件时指定架构来构建XDocument吗？

Question

我是一个尝试从xml文件创建XDocument类型的xml新手。

我可以针对架构验证xml。

public class XmlHandler
{
    public XDocument Read(string filename, string schemaname)
    {
        var schemas = this.GetSchemas(schemaname);
        var doc = XDocument.Load(filename);

        var invalid = false;
        doc.Validate(schemas,
            (o, args) =>
                {
                    this.OnValidationErrors(o, args);
                    invalid = true;
                });

        return invalid ? new XDocument() : doc;
    }

    public XmlSchemaSet GetSchemas(string schemaname)
    {
        var schemas = new XmlSchemaSet();
        schemas.Add(null, schemaname);
        return schemas;
    }

    private void OnValidationErrors(object sender, ValidationEventArgs e)
    {
        Debug.Print("Errors: ", e);
    }
}

但是XDocument的结构似乎是错误的。

运行此代码时

    [Fact]
    public void Read_get_elements()
    {
        var sut = new XmlHandler();

        var result = sut.Read(this.TestFile, this.TestFileSchema);

        var root = result.Root;
        var elements = result.Elements();
        var nodes = result.Nodes();
        var descendants = result.Descendants();

        Assert.NotEmpty(elements);
    }

根变量包含完整的xml字符串，其他IEnumerable变量保持为空。我错过了什么？

编辑： 这是xml和xsd
