Well, delete the '@' and it works for tags too :)

Hi Darren!

That's not completely righ.
Your tests check if the attribute named "tagname" exists, 
not the tag named "tagname".

I've found that the test needs to encompass three possibilities:

1. That the tag is not present;
2. That the tag is empty (ie. tagname=''), or;
3. That the tag is present and contains a value.

If you use test="@tagname", the test will be true in cases 2 and 3. However,
if you use test="not(@tagname='')" (or test="@tagname!=''") then it will
only be true for case 3, at least this is the case with the parser I use. So
it depends on whether or not you want different behaviour when the tag is
missing than you want when the tag is present but empty.

I did not solve the problem, I was going to add the
line that I said oops on in the original message,
sorry for the confusion. I will try this and see if it
works.

Thanks,

Bryan
