<sizes>
−
<size name="original" width="300" height="300">

</size>
<size name="large" width="126" height="126">http://userserve-ak.last.fm/serve/126/2457865.jpg</size>
<size name="largesquare" width="126" height="126">http://userserve-ak.last.fm/serve/126s/2457865.jpg</size>
<size name="medium" width="64" height="64">http://userserve-ak.last.fm/serve/64/2457865.jpg</size>
<size name="small" width="34" height="34">http://userserve-ak.last.fm/serve/34/2457865.jpg</size>
<size name="extralarge" width="252" height="252">http://userserve-ak.last.fm/serve/252/2457865.jpg</size>
</sizes>

 

How would I get each size by their name? So if I wanted to call "small" or "extralarge"?

 

$xmlData->images->image->sizes->size

 

what comes after that? adding ['extralarge'] after size doesn't work.

You could do something similar to the following code snippet. They key thing is the use of the SimpleXMLElement::xpath method.

 

<?php

// ...

foreach ($xmlData->images->image as $image)
{
// SimpleXMLElement::xpath returns an array, we only want the first value
$thumb = current($image->sizes->xpath('size[@name="small"]'));
printf(
	'<img src="%s" width="%d" height="%d" alt="%s"><br>'."\n",
	$thumb,
	$thumb['width'],
	$thumb['height'],
	htmlspecialchars($image->title)
);
}

?>

 

The other option would be to manually loop over the different sizes available until you get to the small one, but the XPath way is much prettier.

I'll try that then, thanks I was considering looping, but I assumed it was simple enough to just add ['extralarge'] or an image size somewhere
