如何将XML个子节点添加到父节点c#

My current xml file looks like this:

 <?xml version="1.0" encoding=""?>
<sheet1>


  <rd>
    <id>45</id>
    <name>alex</name>
    <last>chali</last>
    <phone>33666998565</phone>
    <refF>
      <adresse>41301 US Hwy 280, Sylacauga AL 35150</adresse>
      <citie>NY</citie>
    </refF>
    <age>30</age>
    <mp>
      <degree>2</degree>
    </mp>
    <dpa>1</dpa>
  </rd>
  <rd>
    <id>89</id>
    <name>anna</name>
    <last>marie</last>
    <phone>336465798465</phone>
    <refF>
      <adresse>30 Memorial Drive, Avon MA 2322</adresse>
      <citie>LA</citie>
    </refF>
    <age>28</age>
    <mp>
      <degree>2</degree>
    </mp>
    <dpa>1</dpa>
  </rd>

</sheet1>

What am looking for:

<?xml version="1.0" encoding=""?>
<sheet1>

**<table>  // i want that contain all table rows**

  <rd>
    <id>45</id>
    <name>alex</name>
    <last>chali</last>
    <phone>33666998565</phone>
    <refF>
      <adresse>41301 US Hwy 280, Sylacauga AL 35150</adresse>
      <citie>NY</citie>
    </refF>
    <age>30</age>
    <mp>
      <degree>2</degree>
    </mp>
    <dpa>1</dpa>
  </rd>

  **</table>**
</sheet1>

This is my code:

  string header = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><Sheet1></Sheet1>";
            XDocument doc = XDocument.Parse(header);
            XElement sheet1 = doc.Root;

            foreach (DataRow row in dt.AsEnumerable())
            {
                XElement rd = new XElement("rd", new object[] {
                    new XElement("id", row["id"]),
                    new XElement("name", row["name"]),
                    new XElement("last", row["last"]),
                    new XElement("phone", row["phone"]),
                    new XElement("refF", new object[] {
                        new XElement("adresse", row["adresse"]),
                        new XElement("citie", row["citie"]),
                    }),
                    new XElement("age", row["age"]),
                    new XElement("mp", new XElement("degree", row["mp"])),
                    new XElement("dpa", row["dpa"])
                });

                sheet1.Add(rd);
            }

            doc.Save(FILENAME);

        }

代码显示 'sheet1' 作为包含 'rd' 的根元素，但实际上我希望它作为 'table 中的子元素。我应该如何重新构造它？注意，我只能使用 xDocument 而不是 xmlDocument

Answer 1

1 - 您可以将 table 标签添加到 header，例如：

string header = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><Sheet1><table></table></Sheet1>";

2 - 而不是获取 Root，而是获取 table 元素，例如：

XDocument doc = XDocument.Parse(header);
XElement table = doc.Root.Element("table");

结果

string header = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><Sheet1><table></table></Sheet1>";
XDocument doc = XDocument.Parse(header);
XElement table = doc.Root.Element("table");

foreach (DataRow row in dt.AsEnumerable())
{
    XElement rd = new XElement("rd", new object[] {
        new XElement("id", row["id"]),
        new XElement("name", row["name"]),
        new XElement("last", row["last"]),
        new XElement("phone", row["phone"]),
        new XElement("refF", new object[] {
            new XElement("adresse", row["adresse"]),
            new XElement("citie", row["citie"]),
        }),
        new XElement("age", row["age"]),
        new XElement("mp", new XElement("degree", row["mp"])),
        new XElement("dpa", row["dpa"])
    });

    table.Add(rd);
}
doc.Save(FILENAME);

希望对您有所帮助。
