Implementing XML Product Feed on WordPress Site

Hi there,

My client (http://acticlo.ewebhosting.co.za/) requires an XML product feed to be implemented on their WordPress site. I have now tried about five different plugins, in order to reflect/implement the appropriate products on each page (i.e. http://acticlo.ewebhosting.co.za/sportswear-pretoria/). The following document describes how to implement the product feed, but clearly this is above me: https://www.dropbox.com/s/zs8lxw39x2oea70/Kevro%20Product%20Feed%20Documentation.pdf?dl=0. Does anyone know how I can display the appropriate products on each page via a WordPress plugin? The client’s login particulars, required in the XML string/URL, are as follows:
