How to add line in xml file

Question

I want to add one line in xml file. My xml file contains as follows:

<?xml version="1.0" encoding="UTF-8"?> 
<configuration>     
  <ftp_destination_ip>0.0.0.0</ftp_destination_ip>
  <ftp_destination_user>root</ftp_destination_user>
  <ftp_destination_pass>undefined</ftp_destination_pass>        
  <other_unix_backup_path>/root/BACKUP</other_unix_backup_path>
  <other_backup_folder>BACKUP</other_backup_folder>
  <source_confirmation_needed>false</source_confirmation_needed>
  <keep_ems_running_after_restore>false</keep_ems_running_after_restore>
  <remote_connection_timeout>120000</remote_connection_timeout >
    <history>
        <manage_backup_history>true</manage_backup_history>
        <backup_history_num_of_days>7</backup_history_num_of_days>
    </history>
</configuration>

And I want to add two lines that will be 3th and 4th line in the XML:

  <remote_connection_protocol>sftp</remote_connection_protocol>
  <ftp_destination_ip>0.0.0.0</ftp_destination_ip>

The output should be like that:

<?xml version="1.0" encoding="UTF-8"?> 
<configuration>     
  <!--remote connection protocol>false|ftp|sftp</remote connection protocol-->
  <remote_connection_protocol>sftp</remote_connection_protocol>
  <ftp_destination_ip>0.0.0.0</ftp_destination_ip>
  <ftp_destination_user>root</ftp_destination_user>
  <ftp_destination_pass>undefined</ftp_destination_pass>        
  <other_unix_backup_path>/root/BACKUP</other_unix_backup_path>
  <other_backup_folder>BACKUP</other_backup_folder>
  <source_confirmation_needed>false</source_confirmation_needed>
  <keep_ems_running_after_restore>false</keep_ems_running_after_restore>
  <remote_connection_timeout>120000</remote_connection_timeout >
    <history>
        <manage_backup_history>true</manage_backup_history>
        <backup_history_num_of_days>7</backup_history_num_of_days>
    </history>
</configuration>

Thanks

Try this,

sed '4i\  <remote_connection_protocol>sftp</remote_connection_protocol>\n  <ftp_destination_ip>0.0.0.0</ftp_destination_ip>' file.xml

• 4i to add the content at the 4th line of the file.
• \n for a newline.

if it works, add -i option for inline edit.
