A simpler test script:
<?php
$sx = new \SimpleXMLElement ('<x></x>');
$node = $sx->node;
echo '1: $node = $sx->node => ', get_class ($node), "<br />\n";
$node = $node->node;
echo '2: $node = $node->node => ', gettype ($node), "<br />\n";

Description:
------------
When we invoke a non existent sub-node, SimpleXMLElement returns a
SimpleXMLElement object. But when we try to get a non existent sub-node on that
object, it returns NULL.
IMO this renderes it inconsistent.
Test script:
---------------
<?php
class XXX {
public function test () {
$sx = new \SimpleXMLElement ('<x></x>');
$node = $sx->node;
echo '1: $node = $sx->node => ', $node === $this ? 'this' :
gettype ($node) . ':' . get_class ($node), ' node->count: ', $node->count (),
"<br />\n";
$node = $sx->node->node;
echo '2: $node = $node->node => ', $node === $this ? 'this' :
gettype ($node), "<br />\n";
}
}
$x = new XXX;
$x->test ();
Expected result:
----------------
Or both ($sx and $node) SimpleXMLElement objects should return NULL for a non
existent sub-node or both sould return a SimpleXMLElement object. As it is,
it's a surprise lurking.
I think the second option is best. It makes things like this possible:
if ($products = $sx->Catalog->Products->Product) {
// Never gets here if there's no <Catalog>, or if it has no sub-nodes
// named <Products>, or if it has no sub-nodes named Product.
}
else die ('No products');
Actual result:
--------------
$node it's a SimpleXMLElement, then it is NULL.
1: $node = $sx->node => object:SimpleXMLElement node->count: 0<br />
2: $node = $node->node => NULL<br />
