public class ScriptMain : UserComponent

    //Initialize XML Document to read the XML file
    private XmlDocument xDoc = new XmlDocument();

    public override void PreExecute()

        //Provide the path to read the XML file and load the xml document
        xDoc.Load(@"C:\XML Sample\Input.xml");

    }

    public override void CreateNewOutputRows()
    {
        //Iterate through each node which has the value "Employee" 
        // "//Employee" is the xpath to fetch all occurences of Employee node in the XML
        foreach (XmlNode xNode in xDoc.SelectNodes("//Employee"))
        {
            //Add new row to the output buffer for each employee node in the XML file
            this.EmployeeBuffer.AddRow();

            //Assign values to the columns.

            //Read the 1st attribute of the node Employee
            this.EmployeeBuffer.EmpID= xNode.Attributes[0].Value;

            //Read the 1st Child node of the node Employee
            this.EmployeeBuffer.Name= xNode.ChildNodes[0].InnerText;

            //Read the 2nd Child node of the node Employee
            this.EmployeeBuffer.Age= xNode.ChildNodes[1].InnerText;
        }
    }

    public override void PostExecute()

        base.PostExecute();
    }
