I have downloaded a xml file for my site from a online xml file generator site but their site is saying you have to manually udate the file after some time or by using php or asp this will be updated automatically I have download two files in php "client.php and sitemap.php". But I don't know about php and asp and I also want to submit this in google sitemap which only accept xml format.
Please help me to how to use these two php files.
