XML parser in PHP problem

[SIZE=2]Ok so I did the xml parsing tutorial here (http://www.kirupa.com/web/xml_php_parse_intermediate.htm)and got everything to work.

Now i want to make my XML file an RSS file so people can subcribe to the file. Now the problem is: As soon as i put
[/SIZE][FONT=Arial][SIZE=3]<rss version=“2.0”>

underneath

[/SIZE][/FONT][SIZE=2][FONT=Arial][SIZE=3]<?xml version=“1.0”?>

the php file cant read the xml file anymore.

Does anyone know whats the problem here?[/SIZE][/FONT]
