PHP simplexml problem

Answer 1

+2 A:

I believe its equivalent to the __toString() method on the object, so

echo $description[0];

Should display it, or you can cast it;

$str = (string) $description[0];

That does the tricky nicely. I still find it weird that using print_r still doesn't show any data, while it *is* there... Thanks for the tip !

I think there is some issue with CDATA and SimpleXML. If you try your XML example and remove the CDATA-wrappers, the text will show up. I can't figure out why though.

Answer 3

+8 A:

When you load the XML file, you'll need to handle the CDATA.. This example works:

<?php
$xml = simplexml_load_file('file.xml', NULL, LIBXML_NOCDATA);
$description = $xml->xpath("//item[@title='0x|Beschrijving']");
var_dump($description);
?>

Here's the output:

array(1) {
  [0]=>
  object(SimpleXMLElement)#2 (2) {
    ["@attributes"]=>
    array(4) {
      ["id"]=>
      string(15) "787900813228567"
      ["view"]=>
      string(5) "12000"
      ["title"]=>
      string(15) "0x|Beschrijving"
      ["engtitle"]=>
      string(14) "0x|Description"
    }
    [0]=>
    string(41) "Dit college leert studenten hoe ze een on"
  }
}

Answer 4

+2 A:

Take a look at the PHP.net documentation for "SimpleXMLElement" (http://uk.php.net/manual/en/function.simplexml-element-children.php) it looks like converting the node to a string "(string)$value;" does the trick.

Failing that, there's plenty of examples on that page that should point you in the right direction!
