How to insert data from XML to database

XML is a general purpose tag based language and very easy to transfer and store data across applications. The .Net technology is widely supported XML file format. The .Net Framework provides the Classes for read, write, and other operations in XML formatted files . Moreover the Dataset in ADO.NET uses XML format as its internal storage format.

Here we are going to insert the values of an XML file to a Database Table using SQL Insert Command . Here the Dataset using an XmlReader for read the content of the XML file - Product.XML . Locate the XML file using XmlReader and pass the XmlReader as argument of Dataset. Also establish a connection to the Database using a connectionstring . After getting the data from XML file to the Dataset , we can loop through the dataset values and use insert command to add the values to the Product table in the Databse.

            SqlConnection connection;
            SqlCommand command ;
            SqlDataAdapter adpter = new SqlDataAdapter();
            DataSet ds = new DataSet();
            XmlReader xmlFile ;
            string sql = null;

            int product_ID = 0;
            string Product_Name = null;
            double product_Price = 0;

            connetionString = "Data Source=servername;Initial Catalog=databsename;User ID=username;Password=password";

            connection = new SqlConnection(connetionString);

            xmlFile = XmlReader.Create("Product.xml", new XmlReaderSettings());
            ds.ReadXml(xmlFile);
            int i = 0;
            connection.Open();
            for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
            {
                product_ID = Convert.ToInt32(ds.Tables[0].Rows[i].ItemArray[0]);
                Product_Name = ds.Tables[0].Rows[i].ItemArray[1].ToString();
                product_Price = Convert.ToDouble(ds.Tables[0].Rows[i].ItemArray[2]);
                sql = "insert into Product values(" + product_ID + ",'" + Product_Name + "'," + product_Price + ")";
                command = new SqlCommand(sql, connection);
                adpter.InsertCommand = command;
                adpter.InsertCommand.ExecuteNonQuery();
            }
            connection.Close();
            MessageBox.Show("Done .. ");
        }
    }
}

You have to pass necessary database connection information to connection string.
