如何在每个父节点中包含一个子节点的情况下编写XML文件？

Question

我想要做的是，标题说的是，在文件具有的每个E1EDL24中写入一个E1EDL11标签。仅适用于第一个E1EDL24和E1EDL11标签。从第二个E1EDL11标签开始，下一个被写入第一个E1EDL24标签内。

这是C＃中我所拥有的代码的一部分：

getchar

这是我用来读写文件的XSD文件：

foreach (var vvActualProtDetail in vvProtDetails)
{
    MstProduct vvProduct = new MstProduct()
    { 
        MstBusinessPartnerId = vvCustomerInternalCode, 
        Code = vvActualProtDetail.Product.Trim()
    };

    vvProduct.SelectNew();

    if (vvProduct.Id > 0)
    {
        vvDsSchema.Tables["E1EDL24"].Rows.Add(new object[] {
                                                                "1",
                                                                vvActualProtDetail.RowNumber.ToString().Length < 6 ? vvActualProtDetail.RowNumber.ToString().PadLeft(6, '0') : vvActualProtDetail.RowNumber.ToString(),       //POSNR
                                                                vvActualProtDetail.Product,                                             //MATNR
                                                                "CO01",                                                                 //WERKS
                                                                vvActualProtDetail.WH,                                                  //LGORT
                                                                vvActualProtDetail.Lot,                                                 //CHARG
                                                                vvActualProtDetail.QuantitySent/vvActualProtDetail.Incoming_Quantity,   //LFIMG
                                                                vvActualProtDetail.UoM,                                                 //VRKME
                                                                null,
                                                                "0"
                                                            });

        if (vvActualProtDetail.SN != null && vvActualProtDetail.SN.Trim() != "")
        {
            vvDsSchema.Tables["E1EDL11"].Rows.Add(new object[] {
                                                                    "1",
                                                                    vvActualProtDetail.SN.Trim(),   //SERNR
                                                                    "0"
                                                                });
        }
    }
}

这是我现在得到的：
