There will be three AccruedInterest under PositionDetail . one from the PositionDetail and other two from sub nodes SubAccountDetail

i have written some code to filter but its not working
here is my code
Please help.

C#

public static List<double> serviceaccrued(string cusip,string office,string account,string xmlstring)
     {
         XDocument doc = XDocument.Parse(xmlstring);
         List<double> aacruedlist = doc.Descendants("PositionSummary")
                      .Where(item =>
                      {
                          string cus = (string)item.Element("Cusip");
                          string ofc = (string)item.Element("PositionDetail").Element("Office").Value;
                          string acc = (string)item.Element("PositionDetail").Element("Account").Value;
                          return cus != null && cus == cusip && ofc == office && acc == account;
                      })
                      .ToList().Descendants("AccruedInterest")
                      .Select(acc => Convert.ToDouble(acc.Value)).ToList<double>();
         return aacruedlist;
     }

This is my XML formart

You need to apply filter on PositionDetail instead of PositionSummary.

Try the code below, it will work in your scenario:

C#

List<double> aacruedlist = doc.Descendants("PositionSummary").ToList().Descendants("PositionDetail")
.Where(item =>
{
   string cus = (string)item.Parent.Element("Cusip");
   string ofc = (string)item.Element("Office").Value;
   string acc = (string)item.Element("Account").Value;
   return cus != null && cus == cusip && ofc == office && acc == account;
}).ToList().Descendants("AccruedInterest")
.Select(acc => Convert.ToDouble(acc.Value)).ToList<double>();</double></double>

To get duplicates, try this:

C#

var doubles = xdoc.Descendants("PositionDetail")
            .Descendants("AccruedInterest")
            .GroupBy(item=>item.Value)
            .Select(grp=>new
            {
                AccruedInterest = grp.Key,
                Count = grp.Count()
            });

Result:

AccruedInterest               Count
0.000000000000000000000       2
-883.889000000000000000000    2
883.889000000000000000000     2
