Question

Hey.
I have an XML file and would like to use PHP to display the medium size only. The part of the XML looks like this:

<image size="small">/small23.png</image>
<image size="medium">/medium23.png</image>
<image size="large">/large23.png</image>

I’d like to display the image on the page using <img src="" />, but I’m not sure how to put only the medium image. Within a forloop going through all the other elements, I tried this:

if($file->image->attributes()->size == "medium")
   echo "<img src=$file->image />";

but nothing is drawn.

thanks

Based on your example I assume you’re using SimpleXML, so try this:

$mediums = $file->xpath("image[@size='medium']");
if (count($mediums)) {
    echo '<img src="' . (string) $mediums[0] . '" />';
}
