A pseudo attribute name is expected solution

A pseudo attribute name is expected

If you get the message "A pseudo attribute name is expected" when validating your xml file you have probably done a mistake typing your encoding declaration.
The culprit code should look like :

view source

print?

1.<?xml version="1.0" encoding="UTF-8">

instead of

view source

print?

1.<?xml version="1.0" encoding="UTF-8"?>

There is a very small difference and it has nothing to do with the description of the error message. You have forgotten a question mark at the end of your encoding declaration.
