Question

I know this is very simple question, but I’m apparently terrible at coding and need a bit of advice as I just started using XPath.

I just used the Xpath function $xpath->query("//a[contains(@id, 'title_')]/@href"); to grab a bunch of links. I’m wondering how I manipulate this data, such as store it into an array? I know how to call each part individually (ie: $hrefs->item(0)->nodeValue;) but beyond that I have no clue.

Thanks a bunch!

The query method returns a DOMNodeList. While this itself isn’t an array, you can still iterate over it like an array. For example:

$values = array();
foreach ($hrefs as $node) {
    echo $node->nodeValue;
    $values[] = $node->nodeValue;
    // etc
}
