Noob Needs Help! Importing xml files

[محروم.كوم]

I know this is probably a dumb question, but being the noob I am, I was wondering if anyone could fill me in on how to import the XML file from the server I'm using over into Vbulletin. I have already used the FTP to transfer all the files, however I am lost after that part trying to import the XML files. I am aware that I have to enter the path to the Product-XML-File however, I have no idea how to do that or where to began. If someone could please help assist me, I would really appreciate it. Thank you x)

Side note: If you require this information as well, I am trying to add on, one of the hacks from vbulletin.org. http://www.vbulletin.org/forum/showthread.php?t=101554 __DEFINE_LIKE_SHARE__
