This is what i have tried:
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.UI;  
  6. using System.Web.UI.WebControls;  
  7. using System.Data.SqlClient;  
  8. using System.Data;  
  9. using System.IO;  
  10. using OfficeOpenXml;  
  11. using System.Xml;  
  12.   
  13. public partial class frm_analytics : System.Web.UI.Page  
  14. {  
  15.   
  16.     public Int32 XmlAnalytics(string mFileName, string mElements)  
  17.     {  
  18.         int cnt = 0;  
  19.         try  
  20.         {  
  21.             using (var reader = XmlReader.Create(mFileName))  
  22.             {  
  23.                 while (reader.Read())  
  24.                 {  
  25.                     if (reader.NodeType == XmlNodeType.Element && reader.Name == mElements)  
  26.                     {  
  27.                         cnt++;  
  28.                     }  
  29.   
  30.                 }  
  31.             }  
  32.   
  33.   
  34.   
  35.         }  
  36.         catch (Exception ex)  
  37.         {  
  38.             //webMessage.Show("Error Reading XML files");  
  39.         }  
  40.         return cnt;  
  41.   
  42.   
  43.     }  
  44.   
  45.     protected void Page_Load(object sender, EventArgs e)  
  46.     {  
  47.         //string directoryPath = "D:/TempDir/";  
  48.         string directoryPath = Server.MapPath(string.Format("~/{0}/", "NDRExport"));  
  49.         string[] filePaths = Directory.GetFiles(directoryPath, "*.xml"); //, SearchOption.AllDirectories  
  50.         string fileContent = "";  
  51.   
  52.         /*========================================= 
  53.          * this section is to initialise the Excel header and 
  54.          * the workbook in turn the worksheet

  56.         try  
  57.         {  
  58.             ExcelPackage ps = new ExcelPackage();  
  59.             ps.Workbook.Worksheets.Add("EMR-NDR");

  75.   
  76.             int t = 2;

  87.                // int PrescribedReg = XmlAnalytics(file, "PrescribedRegimen/code");  
  88.   
  89.                 ws.Cells[t, 1].Value = file;  
  90.                 ws.Cells[t, 2].Value = HIVEnCounter;  
  91.                 ws.Cells[t, 3].Value = LaboratoryCounter;

  94.                // ws.Cells[t, 5].Value = PrescribedReg;  
  95.                t++;  
  96.             }  
  97.             //============ Download Excel file =====================  
  98.             //Generate A File with Random name  
  99.             Byte[] bin = ps.GetAsByteArray();  
  100.             string files = directoryPath + "\\EMR-NDR.xlsx";  
  101.             File.WriteAllBytes(files, bin);  
  102.             Response.ClearContent();  
  103.             Response.Buffer = true;  
  104.             Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", files));  
  105.             Response.ContentType = "application/ms-excel";  
  106.             Response.WriteFile(files);  
  107.             Response.End();  
  108.   
  109.             lblErr.Text = "Success....";  
  110.         }  
  111.         catch (Exception ex)  
  112.         {

  114.         }  
  115.     }  
  116. }  
the code above is working very well, i want to in line 87 to test if it can find PrescribedRegimen/code which under the main element <Regimen>
bellow is the portion of the xml file 
  1. <Regimen>  
  2.        <VisitID>7038</VisitID>  
  3.        <VisitDate>2013-09-05</VisitDate>  
  4.        <PrescribedRegimen>  
  5.          <Code>1e</Code>  
  6.          <CodeDescTxt>TDF/3TC/NVP</CodeDescTxt>  
  7.        </PrescribedRegimen>  
  8.        <PrescribedRegimenTypeCode>ART</PrescribedRegimenTypeCode>  
  9.        <PrescribedRegimenDuration>56</PrescribedRegimenDuration>  
  10.        <PrescribedRegimenDispensedDate>2013-09-05</PrescribedRegimenDispensedDate>  
  11.        <DateRegimenStarted>2011-02-10</DateRegimenStarted>  
  12.      </Regimen>  
  13.      <Regimen>  
  14.        <VisitID>7598</VisitID>  
  15.        <VisitDate>2013-10-31</VisitDate>  
  16.        <PrescribedRegimen>  
  17.          <Code>1e</Code>  
  18.          <CodeDescTxt>TDF/3TC/NVP</CodeDescTxt>  
  19.        </PrescribedRegimen>  
  20.        <PrescribedRegimenTypeCode>ART</PrescribedRegimenTypeCode>  
  21.        <PrescribedRegimenDuration>84</PrescribedRegimenDuration>  
  22.        <PrescribedRegimenDispensedDate>2013-10-31</PrescribedRegimenDispensedDate>  
  23.        <DateRegimenStarted>2011-02-10</DateRegimenStarted>  
  24.      </Regimen>  
I appreciate any help.
