我有以下xml字符串，我试图根据动态列集查询数据表。我没有对xml的任何控制，它是从外部源传入的。

输出中所需的动态字段列表（这是从DB读入并且可以更改）：
ParameterName ParameterPath
AdjusterEmail //MasterCarrierInfo//AdjusterEmail
EmpCode //MasterCarrierInfo//EmployerCode
SOJ //MessageBody//SOJ
DOI //MessageBody//DOI
GPI //MessageBody//Details//Detail//GPI
BlockCode //MessageBody//Details//Detail//Blocks//Block//BlockCode
我需要把它读成一个看起来像这样的表：
AdjusterEmail EmpCode SOJ DOI GPI BlockCode
STEPHAN.WILLIAMS@example.COM 00000016 OH 20131006 75100012333720 75*ndc
STEPHAN.WILLIAMS@example.COM 00000016 OH 20131006 75100012333720 76*ndc
STEPHAN.WILLIAMS@example.COM 00000016 OH 20131006 12345678901234 75*ndc
每个MessageBody可以有多个详细记录，每个详细信息可以有多个Block记录
我真的不知道从哪里开始，我已经尝试了很多不同的东西，包括linq（我不知道）并且无法解决这个问题......

有效：
XDocument xd = null;
using (StreamReader oReader = new StreamReader(xmlFilePath, Encoding.GetEncoding("ISO-8859-1")))
{
xd = XDocument.Load(oReader);
}
var records = from root in xd.Descendants("MessageBody")
from details in root.Elements("Details").Elements("Detail")
select new
{
AdjusterEmail = root.Element("AdjusterEmail").Value,
EmpCode = root.Element("MasterCarrierInfo").Element("EmployerCode").Value,
SOJ = root.Element("SOJ").Value,
DOI = root.Element("DOI").Value,
GPI = details.Element("GPI").Value,
BlockCode = details.Element("Blocks").Element("Block").Element("BlockCode").Value
};
创建数据表以保存记录：
DataTable dt = new DataTable();
dt.Columns.Add("AdjusterEmail", typeof(string));
dt.Columns.Add("EmpCode", typeof(string));
dt.Columns.Add("SOJ", typeof(string));
dt.Columns.Add("DOI", typeof(string));
dt.Columns.Add("GPI", typeof(string));
dt.Columns.Add("BlockCode", typeof(string));
DataRow dr = null;
foreach (var readValue in records)
{
dr = dt.NewRow();
dr["AdjusterEmail"] = readValue.AdjusterEmail;
dr["EmpCode"] = readValue.EmpCode;
dr["SOJ"] = readValue.SOJ;
dr["DOI"] = readValue.DOI;
dr["GPI"] = readValue.GPI;
dr["BlockCode"] = readValue.BlockCode;
dt.Rows.Add(dr);
}
dt包含如下：
AdjusterEmail EmpCode SOJ DOI GPI BlockCode
STEPHAN.WILLIAMS@COMP.COM 00000016 OH 20131006 75100012333720 75*ndc
STEPHAN.WILLIAMS@example.COM 00000016 OH 20131006 75100012333720 76*ndc
STEPHAN.WILLIAMS@example.COM 00000016 OH 20131006 12345678901234 75*ndc

您可以使用下面的方法并将您的xml文件路径作为输入传递
DataSet ds = new DataSet();
ds.ReadXml("Your File Path");
您将拥有数据集，其中包含xml的相应数据集对象。
