Hi @MahmudurRahman3!
Thank you for reaching out to us!
I understand that you would like more information on the XML code. As coding is a bit complex, we do have a valid example here and do recommend that you reach out to your webmaster to mirror this within your feed.
I hope this information is useful to you. If you would like further support, please do let me know and I will do my best to continue assisting you!
Thank you,
