  i have this code, i want to implement it to asp.net and call a button function so that when you click on it, it will generate a PDF with the result of that id.

  this is my code. I'm open for any help and ideas 

  thanks in advance

  using System;
  using System.Linq;
  using System.Xml;
  using System.Xml.Linq;
  
  public class Program
  {
  public static void Main()
  {
      string str = @"<?xml version='1.0'?>
                      <information>
                      <details>
                      <id>01</id>
                      <empname>qwer</empname>
                      <empid>001</empid>
                      <dept>Accounts</dept>
                      <date>2011-01-15 12:21:25</date>
                      </details>
                      <details>
                      <id>02</id>
                      <empname>jdfklgd</empname>
                      <empid>002</empid>
                      <dept>Finance</dept>
                      <date>2011-01-20 10:21:25</date>
                      </details>
                      </information>";
  
      var str1 = XElement.Parse(str);
  
      //Search ID
      string searchID = "01";
  
      //Get Result
      var result = str1.Elements("details").Where(x => x.Element("id").Value.Equals(searchID)).ToList();
  
      if(result.Count() > 0)
      {
          //Get Specific element value
          string s = result[0].Elements("empname").FirstOrDefault().Value;           
          Console.WriteLine(s);
      }
  }
  }

  Hi tandohtakyie,

  I suggest you could refer to the following code:

  After parsing the XML element, you could use the DetailsView control or some Label control to display the result, then, using the ITextsharp  library to export the web page to PDF file.

  Code as below:

  <%@ Page Language="C#" AutoEventWireup="true" EnableEventValidation="false" CodeBehind="ExportToPDF.aspx.cs" Inherits="WebSample.General.ExportToPDF" %>
  
  
          <div>
              <table>
                  <tr>
                      <td>ID:</td>
                      <td>
                          <asp:Label ID="lblID" runat="server" Text=""></asp:Label>
                      </td>
                  </tr>
                  <tr>
                      <td>Name:</td>
                      <td>
                          <asp:Label ID="lblName" runat="server" Text=""></asp:Label>
                      </td>
                  </tr>
              </table>
  
              <asp:Button ID="btnExport" runat="server" Text="Export" OnClick="btnExport_Click" />
          </div>

  Code behind:

  using System.Xml.Linq;
  using iTextSharp.text;
  using iTextSharp.text.html.simpleparser;
  using iTextSharp.text.pdf;
  
          protected void Page_Load(object sender, EventArgs e)
          {
              string str = @"<?xml version='1.0'?>
                      <information>
                      <details>
                      <id>01</id>
                      <empname>qwer</empname>
                      <empid>001</empid>
                      <dept>Accounts</dept>
                      <date>2011-01-15 12:21:25</date>
                      </details>
                      <details>
                      <id>02</id>
                      <empname>jdfklgd</empname>
                      <empid>002</empid>
                      <dept>Finance</dept>
                      <date>2011-01-20 10:21:25</date>
                      </details>
                      </information>";
  
              var str1 = XElement.Parse(str);
  
              //Search ID
              string searchID = "01";
  
              //Get Result
              var result = str1.Elements("details").Where(x => x.Element("id").Value.Equals(searchID)).ToList();
              if (result.Count() > 0)
              {
                  lblID.Text = searchID;
                  lblName.Text = result[0].Elements("empname").FirstOrDefault().Value;
              }
          }
  
          protected void btnExport_Click(object sender, EventArgs e)
          {
              Response.ContentType = "application/pdf";
              Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
              Response.Cache.SetCacheability(HttpCacheability.NoCache);
              StringWriter sw = new StringWriter();
              HtmlTextWriter hw = new HtmlTextWriter(sw);
              this.Page.RenderControl(hw);
              StringReader sr = new StringReader(sw.ToString());
              Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
              HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
              PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
              pdfDoc.Open();
              htmlparser.Parse(sr);
              pdfDoc.Close();
              Response.Write(pdfDoc);
              Response.End();
          }
