Thanks a lot to all :)
Using DOM I can do what I need. Anyway I was trying the proposed solutions
with SimpleXML but none of them worked for me :(
I tried splitting $key and $value in the foreach command, but when I dump
the xml (with the asXML function) I still have the nodes that I supposed to
delete... And the same using references, cause I think using unset with
referenced variable names doesn't delete the referenced var, it just deletes
the link to the referenced var...
Concretely I tried:
TEST ONE:
foreach ($xmlDatabase as $key => $oneTable) if ($oneTable['name'] == 'one')
unset($xmlDatabase[$key]);
$sourceXML = $xmlDatabase->asXML(); // <----- node <table name='one'> is
still there
TEST TWO
foreach ($xmlDatabase as $key => &$oneTable) if ($oneTable['name'] == 'one')
unset($oneTable);
$sourceXML = $xmlDatabase->asXML(); // <----- node <table name='one'> is
still there
If there's no luck with xml I will use of course DOM for this, but I'm
really curious now :P
Again, thanks a lot for the help.

The answer is simple, everybody else seems to have missed it. foreach()
makes a copy of the array before working on it. Changes made to
$oneTable would obviously never affect the original. You're just
unsetting a temporary variable that's going to be overwritten next time
through the loop anyhow.
You should have better luck with this code:
$xmlDatabase = new SimpleXMLElement($myXML);
foreach ($xmlDatabase as $key => $oneTable)
fwiw, In php5 you can do something like:
foreach ($xmlDatabase as $key => &$oneTable)
//note the & ------------------^^^^
unset($oneTable);
