I have a registered domain plus hosting and connect its ftp with blogger.com. Pages are uploaded via ftp on my hosting. I need to use passionduo blue template though when I downloaded the themplate I found .xml file instead of htm codes to replace with the default html code of default template of blogger.com .

what to do ? should I not use my own hosting space ?? should use only domain name point to blogger.com's hosting managing DNS ?

Please advice
