Hi, If I'm not mistaken the pattern match for the second meta.tag.xml rule is missing _ as a valid character for the attribute name. The correct match should be: match = ' (?:([-_a-zA-Z0-9]+):)?([_a-zA-Z-]+)' Regards, Aparajita www.aparajitaworld.com "If you dare to fail, you are bound to succeed." - Sri Chinmoy | www.srichinmoylibrary.com
