How to view object's data in php

Question

Hello

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?

Thanks

Answer 1

var_dump($myobject); may be what you're looking for

Answer 2

Your xpath query is not matching anything in your XML.

From the DomXPath::query manual page:

Returns a DOMNodeList containing all nodes matching the given XPath expression . Any expression which do not return nodes will return an empty DOMNodeList.

Answer 3

How about a recursive function?

Function XMLPrint_r($d_DomNode) {
    print $d_DomNode->$nodeName." ".$d_DomNode->$nodeValue."<br>";
    Foreach($d_DomNode->$childNodes as $d_ChildNode) {
        print " ";
        XMLPrint_r($d_ChildNode);
    }
}

I did not test this, but you get the idea.
