XML validation problem

[tinggg]

Hi

When I use a url with more than one = symbol e.g.

http://www.fis.org.nz/index.php?map=yes&app=BreakOut

the xml fails to validate. The reason given is that "the production 'entity ref' not satisfied"

- I looked up the entity escape character for = and got

& # 6 1 ;

[I had to seperate the & # 6 1 ; with a space between each character in order to get them to appear here]

- I replaced the = with the entity escape character but that didn't work either.

Can anyone help me with where I am doing wrong?

Many thanks
