Question

I’m trying to retrieve the the HREF and echo it out using SimpleXML, but I keep getting the error message below.

Warning: Invalid argument supplied for foreach() in …

<?php

$url = 'file.xml';

foreach(simplexml_load_file($url)->info->content->item as $it) {
    echo $it->site-page-href;
}

?> 

<?xml version="1.0" encoding="utf-8"?>
<info>
    <content>
        <item>
            <site>
                <page>
                    <href>http://domain.com</href>
                </page>
            </site>
        </item>
    </content>
<info>

Can anyone spot the problem?

Answer 1

1. echo $it->site-page-href;
   should be echo
$it->site->page->href;
2. Your
   end tag should be </info>
3. You should not use ->info as you
   are already at the root element.
   ie.
   simplexml_load_file($url)->content->item
   not
   simplexml_load_file($url)->info->content->item

Btw, finding all of the href nodes can be achieved more easily if you use xpath.

 $xml = simplexml_load_file($url);
 $href = $xml->xpath(".//href");
 foreach($href as $h) {
    var_dump($h);
 }
