Question

How do I return the value of the owner and id attributes respectively from an XML result set using PHP?

Answer 1

A:

I use XML_Unserializer from PEAR


$options = array(
    'complexType' => 'object',
    'encoding' => 'utf-8',
    'parseAttributes' => TRUE,
    'returnResult' => TRUE
);
$xr = new XML_Unserializer($options);
$images = $xr->unserialize($images);

$flickrPhotoUrl = 'http://www.flickr.com/photos/';

foreach($images->photos as $photo)
{
$flickrPhotoUrl .= $photo->owner;
}

I tried this a few different ways myself, and failed every time (getting a "Invalid document end at XML input line 1:1" error, even with validated XML/RSS contents). Also, I found that I needed to add "require_once 'XML/Unserializer.php';" before calling the XML_Unserializer object.

Yes the require is how to include the PEAR library. If we are looking at the sample data above - there is no finishing </photos> - I use this PEAR object on a production site that runs unserializations all day long with no problems - it might be the version you have installed

Answer 2

+1 A:

You can use PHP's SimpleXML to manipulate/traverse to your XML easily. Assuming you have your resulting your resulting xml string stored in $images,

$images_xml = simplexml_load_string($images);
$flickr_url = "http://flickr.com/photos/";

foreach($images_xml->children() as $image)
{
     $attributes = $image->attributes();
     $image_url = $flickr_url . $attributes->id;
     //Do whatever you want to do with the link
     //for example, echo it
     echo "<br /><a href=\"". $image_url ."\">" . $attributes->title . "</a>";

     //Not sure if the link points to an actual image, but is the idea :)
}

Hope that helps.
