Question

This is driving me crazy, I am trying to get to a specific part of this object and it is driving me crazy, here is the object contents:

XMLHandler Object
(
    [doc:XMLHandler:private] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [state] => Live
                )

            [newsListItem] => Array
                (
                    [0] => SimpleXMLElement Object
                        (
                            [@attributes] => Array
                                (
                                    [href] => http://api.contentplus.co.uk/6cb5ea15-d6b1-4c40-9db7-cb2a3315080b/news/800773226/
                                )

                            [id] => 800773226
                            [publishDate] => 2011-10-24T10:04:49
                            [lastModifiedDate] => 2011-10-24T11:20:40
                            [headline] => Relationships matter on social media
                        )

                )

        )

    [format] => html
) 

I want to get the value of [id] I am trying to access it like this:

echo $niList->doc->newsListItem[0]->id;

but this is giving me nothing, I know I am close (well I hope I am) but I just cant quite get it right, could anyone help please.

Thanks all.

Your object dump says

doc:XMLHandler:private

which means doc is a private property of XMLHandler. As such, you can only access it from within that object via $this. But you are trying to access it from outside the object when you do

echo $niList->newsListItem[0]->id;

This wont work. Add a method to that XMLHandler object that does what you want to do with that newslistitem id. Also see the chapter on Visibility in the PHP Manual:
