使用Xml Linq：

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

namespace ConsoleApplication139
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            string[] changeRows = { "field62", "field63", "field64", "field65", "field66" };
            XDocument doc = XDocument.Load(FILENAME);

            foreach(XElement row in doc.Descendants().Where(x => changeRows.Contains(x.Name.LocalName )))
            {
                row.SetValue("1");
            }

        }
    }
}
