Question

I’m trying to use an xml file and retrieve all links from it. so far I have:

$xmlHeadline = $xml->channel[0]->item[3]->link;
print($xmlHeadline);

This works ok to print the single headline link for item[3] in the xml. But as you can see it is 2 levels deep. Then next one will be at channel[0]->item[4]->link. There is no channel 1, just channel[0].

All the examples on the internet only deal with 1 level deep. They all used a foreach loop, but I am not sure if that can be used here…

How can I cycle through all item’s in the xml and echo all links?

Answer 1

Try

foreach ($xml->channel[0]->item as $item) {
    echo $item->link;
}

or

foreach ($xml->xpath('/channel/item/link') as $link) {
    echo $link;
}
