So is generically processing child elements. Besides, if there is one
technology worth learning when it comes to processing XML its Xpath.
Its XML's SQL/regular expressions, draw what analogies to string processing
that you will, but I don't see:
$results = simplexml_query($element, '/child::node()');
foreach ($results as $result) {
echo $result;
}
Signifigantly more complex then:
$results = $element->getChildren();
foreach ($results as $result) {
echo $result;
}
And it comes with the advantage of being a *signifigantly* more
powerful abstraction.
