PHP SimpleXml - Getting attributes of children with names

Question

I am parsing an external Atom feed, some entries contain a collection of children with names - I do not get attributes from these children. Short example:

$feed = <<<EOD
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:ai="http://activeinterface.com/thincms/2012">
  <entry>
    <title>Some Title</title>
    <ai:image>path/to/some/image</ai:image>
    <ai:ocurrence dateid="20120622" date="Fri, June 22, 2012" time="6:00 pm" />
    <ai:ocurrence dateid="20120720" date="Fri, July 20, 2012" time="6:00 pm" />
  </entry>
</feed>
EOD;


$xml = new SimpleXmlElement($feed);
foreach ($xml->entry as $entry){
  echo $entry->title;
  $namespaces = $entry->getNameSpaces(true);
  $ai = $entry->children($namespaces['ai']);
  echo $ai->image;
  foreach($ai->ocurrence as $o){
    echo $o['date'];
  }
}

Everything except the attribute for searching for children with names works fine - if the tags of the children do not take up space, they work fine. If you grab the node value (and not the attribute), even if the namespace works, it works fine. What am I missing?

Answer 1

try it

    $xml = new SimpleXmlElement($feed);
    foreach ($xml->entry as $entry)
    {

        $namespaces = $entry->getNameSpaces(true);
        $ai = $entry->children($namespaces['ai']);

        foreach ($ai->ocurrence as $o)
        {
            $date=$o->attributes();
            echo $date['date'];
            echo "<br/>";
        }
    }

I don’t know why, but apparently access to the array will not be here ... we need an attribute method:

echo $o->attributes()->date;
