Question

I have an xml string below that I’ve turned into an object using

$content = mb_convert_encoding($content, "ASCII");
$obj = new SimpleXMLElement($content);

The structure of obj is perfectly matching the xml. However trying to get an array of sets without the parent “set” node is causing me issues.
I do

foreach($obj->group as $currentGroup)
{

From inside here if I do $currentGroup->sets I then see a set node with numbering under it, 0 and 1, and under it the structure of the subtest.
My problem is it I try to do $currentGroup->sets->set (to try to get an array of sets without the parent then I get the first set automatically and none of the others ones.

                    <subset name="bla2"/>
                    <subset name="bla3"/>

Answer 1

So you want an array of the set nodes? Should be $currentGroup->sets->children() unless I’m missing something.
