</picture>
</pictures>
</ad>
</treeplat>

I parse the xml file in this way:

$xml = simplexml_load_file(storage_path('app'.DIRECTORY_SEPARATOR.'public'.DIRECTORY_SEPARATOR.$percorso_file.'test.xml')); 
foreach ($xml->ad as $immobile) {
...
}

My problem is tag. I try to extract the first only using this code:

$picture_url_1 = (string)$immobile->pictures->picture->picture_url

but I don't try to extract every picture_url.

How can I parse all the pictures tag?

Many thank's!

Answer 1

you are looping over the wrong variable. what you need is:

$pictures = $xml->ad->pictures->picture;
foreach ($pictures as $picture) {
    echo $picture->picture_url;
}

(you can replace echo with whatever command you need)

Answer 2

Gilad almost had it!

$pictures = $xmlData->ad->pictures;
foreach($pictures as $picture)
{
   foreach($picture as $pic)
   {
      echo (string) $pic->picture_url;
   }
}
