Hi, extracting Specific XML Node data from XML file and placing to DataTable is pretty simple, Find the below XML file where specific Node I have taken is <TABLES>, From <TABLES> Each <TABLE> information is collected to the DataTable.

XML: Myfile.xml

<BATCHEXTRACT>
  <DBDETAILS>
    <SQLCONNECTIONSTRING>server=dev.logs;database=DB;uid=admin;pwd=ast</SQLCONNECTIONSTRING>
    <CONNECTIONTIMEOUT>2000</CONNECTIONTIMEOUT>
  </DBDETAILS>

  <LOGFILE>
    <LOGFILEPATH>D:PURGE_BATCH/LogFile</LOGFILEPATH>
    <LOGFILENAME> BATCH_LogFile.log</LOGFILENAME>
  </LOGFILE>

  <TABLES>
    <TABLE>
      <Name>T_dATA_LOG</Name>
      <NoOfDay>18</NoOfDay>
      <dateColumn>CRT_DT</dateColumn>
    </TABLE>
    <TABLE>
      <Name>T_INBOUND_LOG </Name>
      <NoOfDay>18</NoOfDay>
      <dateColumn>CRT_DT</dateColumn>
    </TABLE>
    <TABLE>
      <Name>T_DELETE_LOG</Name>
      <NoOfDay>18</NoOfDay>
      <dateColumn>CRT_DT</dateColumn>
    </TABLE>
    <TABLE>
      <Name>T_MERGE_LOG</Name>
      <NoOfDay>28</NoOfDay>
      <dateColumn>CRT_DT</dateColumn>
    </TABLE>
    <TABLE>
      <Name>T_ALPHA_DETAILS</Name>
      <NoOfDay>18</NoOfDay>
      <dateColumn>CRT_DATE</dateColumn>
    </TABLE>
  </TABLES>

</BATCHEXTRACT>

C#

public DataTable GetTableNames()
        {
            try
            {
                XmlDocument Docs = new XmlDocument();
                Docs.Load("Myfile.xml");
                XmlElement root = Docs.DocumentElement;
                DataTable dt = new DataTable();
                dt.Columns.Add("Name");
                dt.Columns.Add("NoOfDay");
                dt.Columns.Add("dateColumn");
                XmlNodeList nodes = root.SelectNodes("//TABLES/TABLE");
                foreach (XmlNode node in nodes)
                {
                    dt.Rows.Add(node["Name"].InnerText.ToString(),
                                node["NoOfDay"].InnerText.ToString(),
                                node["dateColumn"].InnerText.ToString()
                               );
                }
                return dt;
            }
            catch (Exception es)
            {
                throw es;
            }
        }
