DomDocument; hasChildNodes but Foreach not showing children?

[redgenieuk]

Morning! I have started using DOMdocument for a job but hit an issue with this code snippet.

 

 

     if ($txtnode1->parentNode->hasChildNodes()) {
                                Echo "***Has Children Start***<br>";
                                foreach ($txt1->parentNode as $child) {
                                    Echo "NodeChild<br>";        
                                }
                                Echo "***Has Children End***<br>";
      }

I get the output:

***Has Children Start***
***Has Children End***

So 

($txtnode1->parentNode->hasChildNodes())

is true;

But

foreach ($txtnode1->parentNode as $child)

Isn't looping.... I think indicating  there are no children?

But there must be a child.... because we are going to $txtnode1's parentNode... so in summary i am very confused!

Any help greatly appreciated. TIA.

Stupidity has been found. I am answering my own question as I cannot see how to remove it; but hopefully it might help someone else one day!

Answer is:

foreach ($txtnode1->parentNode as $child)

should be

foreach ($txtnode1->parentNode->childNodes as $child)
