Am I a doofus?

[Thomas P. N. <as...@mi...>]

Hi list,

I've noticed a lot of differences in migrating from v2.2 to v3.3.

For instance, this was possible in v2.2:

$myxpath = new xpath();
$myroot = $myxpath->appendChild("","superroot");

.. but not in v3.3. Furter, in v2.2 a query through evaluate() to an 
unique xpath would produce a string, whereas v3.3 produces an array
There are workarounds for it, but none the less - I've had numerous 
encounters of the odd kind to which I can seem to find no obvious solution.

Can anyone tell me if I can find documentation on the differences in 
implementation? Or, preferably; different examples on usage?

I suspect being a doofus, but I'd really like to get this sorted out.

Thank you for any help in advance.

Sincerely,

Thomas Pilgaard
