Question

现在，我正在尝试提供一些服务，以便我可以读取xml文件并将其解析为sql服务器，我已经阅读并看到了许多教程如何使用c＃将xml解析为sql服务器，但仍然无法使用数据。

<?xml version="1.0" encoding="utf-8" ?>
<Source 1 - Subject 17>
    SubjectType: Faces
    FaceConfidence: 100

        <Details available on frame 1050> 
            FrameIndex: 1050
            Status: Ok
            Eyes at: (260; 169) and (229; 169)

这是xml文件格式，这是我的尝试：

protected void Button1_Click(object sender, EventArgs e)
{
    string cs = @"Data Source=172.16.6.39;Initial Catalog=FC_SCAN;Persist Security Info=True;User ID=fc_adm;Password=P@ssw0rd";
    SqlConnection con = new SqlConnection(cs);

    XmlDocument doc = new XmlDocument();
    doc.Load("test.xml");

    var source = doc.DocumentElement.SelectNodes("Source").Cast<XmlElement>().ToList();

    var appeared = source[0].GetAttribute("Appeared");
    var disappeared = source[0].GetAttribute("Disappeared");
    var top = source[0].GetAttribute("Top");

    SqlCommand cmd;
    SqlDataAdapter da = new SqlDataAdapter();
    string sql = null;
    con.Open();
    sql = "Insert into Source values ('" + source + "','" + appeared + "','" + disappeared + "','"+top+"')";
    cmd = new SqlCommand(sql, con);
    da.InsertCommand = cmd;
    da.InsertCommand.ExecuteNonQuery();
    con.Close();
}

错误控制台始终显示在xml文件中，我非常感谢任何帮助，技巧或提示。

Answer 1

启动代码时，我立即在处收到异常

 doc.Load("test.xml");

行。异常消息很清楚：

An unhandled exception of type 'System.Xml.XmlException' occurred in System.Xml.dll
Additional information: Name cannot begin with the '1' character, hexadecimal value 0x31. Line 2, position 9.

显然，它不喜欢名为“源1-主题17”，“出现在02/08/2018 5:28:43 PM”等的XML标签。

更新：

您不能使用.Net XML操纵的东西，因为您的文件不是XML（它声称是带有标头的XML，但是有点儿谎言）。如果仍然需要将此文件的内容放入数据库，则必须编写一个自定义解析例程以读取该自定义数据格式，或者，如果可能的话，请与为您生成“ XML”的人员联系并说服他们将其数据格式更改为真实的XML。如果您在同一组织等中工作，这可能是最简单的方法。

您的xml太糟糕了。我将其固定在下面：

<?xml version="1.0" encoding="utf-8" ?>
<Source>
  <SubjectType>Faces</SubjectType>
  <FaceConfidence>100</FaceConfidence>
  <appeared>
    02/08/2018 5:28:43 PM>

    <Rectangle top="210" left="169" width="63" height="84"/>
  </appeared>

我对 jdweng 的回答不是100％，但是他的想法告诉我实际上应该有多个根元素。所以我的想法是，每个来源都有自己的来源和主题ID。

    <?xml version="1.0" encoding="utf-8" ?>

<Source id="1">
<Subject id="17">
