PHP parsing xml with node children-CodePudding

The RSS feed https://moxie.foxnews.com/feedburner/world.xml contains items like:

<link></link>
<title></title>
<media:group>
  <media:content url="*.jpg" medium="image" isDefault="true"/>
  <media:content url="*.jpg" medium="image" width="60" height="60"/>
</media:group>
<media:thumbnail url="*.jpg" width="60" height="60"/>

I know how to display the contents of <link> and <title> but can anyone help me display the media URLs inside <media:group><media:content> and <media:thumbnail>? Thanks

CodePudding user response：

I've cleaned up the badly formed XML so it parses and provided a way to see what the errors are.

$xml = '<media:group>
  <link></link>
  <title></title>
  <media:content url="*.jpg" medium="image" isDefault="true"></media:content>
  <media:content url="*.jpg" medium="image" width="60" height="60"></media:content>
</media:group>';

libxml_use_internal_errors(true);
$doc = simplexml_load_string($xml);
if ($doc === false) {
  $errors = libxml_get_errors();
  print_r($errors);
} else {
  print_r($doc);
}

result

SimpleXMLElement Object
(
    [link] => SimpleXMLElement Object
        (
        )

    [title] => SimpleXMLElement Object
        (
        )

    [media:content] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [url] => *.jpg
                            [medium] => image
                            [isDefault] => true
                        )

                )

            [1] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [url] => *.jpg
                            [medium] => image
                            [width] => 60
                            [height] => 60
                        )

                )

        )

Thanks for the clarification.
