Question

I’m trying to get all categories and push them into my array, so far I’m doing it this way:

  $doc = new DOMDocument();
  $doc->load('myxml.xml');
  $arr = array();
  foreach ($doc->getElementsByTagName('item') as $node) {
    $items = array ( 
      'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
      'date' => $node->getElementsByTagName('category')->item(0)->nodeValue
      );
    $arr [] = $items ;
  }

This works if we have only 1 cat, however, my xml has several categories per item. What would be a good way of doing this?

<item>
  <title>Submit</title>
  <category>Foo</category>
  <category>Bar</category>
</item> 

Thanks

This should help:

$doc = new DOMDocument();
$doc->load('myxml.xml');
$arr = array();
foreach ($doc->getElementsByTagName('item') as $node) {
    $item = array ( 
        'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
        'date' => array()
    );

    foreach($node->getElementsByTagName('category') as $catNode)
    {
        $item['date'][] = $catNode->nodeValue;
    }

    $arr[] = $item;
}
