when I want to test php array I use the following code

```
    print_r($myarray);

```

but know I want to see the data of an object
my object is 

```
    $xpath = new DOMXPath($doc);
    $myobject = $xpath->query('//*[ancestor-or-self::a]');

```

when I use

```
    print_r($myobject);

```

I get that output

```
    DOMNodeList Object ( )

```

I want to iterate through the values of this object to test the result of my query?
