Want to make live XML link for price comparision website like Junglee,mysmartprice,buyhatke etc and want to integrate shipping service API to my prestashop website -- 2

Job 1) I am using prestashop V1.6.0.6 and using a free module "PrestaCenter XML Export Free v1.2.3.1" which makes XML live link for price comparison website like [login to view URL], [login to view URL], [login to view URL] etc, but here I am stuck, there is some line of code it is asking me to write, I wrote some script looking at the sample and made one link but when i tried uploading the same to [login to view URL] and [login to view URL] so it didn't get accepted and got an error, it seems that all price comparison website needs different format XML link for my products to flow in their website seamlessly, i need your help on this, i want you to write some link of codes and make 10 XML links for 10 best price comparison website, so that whatever product i put on my website it should get uploaded on these website seamlessly.. Job 2) I am using an automated shipping service called [login to view URL], they have ready made module for opencart and magento but they do not have any ready made module for prestashop so I would like you to make that module for me using their API, so that I don't have to manually add orders into their admin panel, checkout attached photos for XML module
