查询存储在属性中的XML值并使用C＃导入到数据集中

Question

I am new to c# in general and new to parsing xml. I have an xml stream that I am getting from a web service that has values in attributes that I want to load into my SQL Server using a dataset/datatable. I am having a hard time getting the data in the structure that I want to import into SQL.

I would like to pull the data (for each into a tables in the following structure:

Columns: bounce_date cancellation_mailing_instance_id cancellation_message cancellation_date email, etc.

Rows: bounce_date "value" cancellation_mailing_instance_id "value" cancellation_message "value" cancellation_date "value" email "value", etc.

So far all I can accomplish is getting all the data into rows. I would like to create the column headers based on , etc

...and the Rows based on "Value" "Value", etc.

My XML is coming over as follows:

<?xml version="1.0" encoding="ISO-8859-1"?>

<Brand id="12345">ACME</Brand>

So far I am trying Linq To XML. I would be eternally grateful if someone could provide a little code sample to get me started! Thanks in advance.

He is some real simple Xml Linq that reads results into a dictionary

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;

namespace ConsoleApplication110
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            string xml = File.ReadAllText(FILENAME);
            XDocument doc = XDocument.Parse(xml);
            XElement root = doc.Root;
            XNamespace ns = root.GetDefaultNamespace();

            Dictionary<int, List<string>> results = doc.Descendants(ns + "Record")
                .GroupBy(x => (int)x.Attribute("row"), y => y)
                .ToDictionary(x => x.Key, y => y.Descendants(ns + "Field").Select(z => (string)z.Attribute("element")).ToList());
        }
    }
}
