Remove a xml node in php

Question

my xml file:

<temporary>
  <users>
    <temp>
      <id>1</id>
      <title> Undercover</title>
      <author>Wiwit</author>
    </temp>
    <nissi>
      <confirm>3977678bce8515e8cdbfa64850904ad1</confirm>
      <firstname>hi</firstname>
      <lastname>hhey</lastname>
      <day>1</day>
    </nissi>
   </users>
</temporary>

my php:

<?php
$user="nissi";
$xml = simplexml_load_file("temporary.xml") 
       or die("Error: Cannot create object");
unset($xml->temporary->users->$user);
?>

Why is this not working. The unset is not working.The node ins'nt getting deleted.

What fails? The file loading or the `unset()` call? – Michael Berkowski Mar 07 '11 at 15:57 — Michael Berkowski, Mar 07 '11 at 15:57

It works like this :

$user="nissi";
$xml = simplexml_load_file("temporary.xml") 
       or die("Error: Cannot create object");
unset($xml->users->$user);
echo $xml->asXML();

You mustn't take the root of your xml in the "request" temporary here.

Exactly! Use the $xml object to proof! – powtac Mar 07 '11 at 16:57
Just call the variable the same name as the root node, it will prevent that kind of mixups. – Josh Davis Mar 07 '11 at 17:55
@Josh Davis : It's a great advice for beginners :) – Shikiryu Mar 07 '11 at 18:21
Yeah, that's just about the best advice I can ever give to any SimpleXML user :) That, and also that they don't consider SimpleXMLElement as some kind as array that they can inspect with `print_r()` but that one is a bit too cryptic. – Josh Davis Mar 08 '11 at 15:47

You cannot do it with SimpleXML alone, you have to use DOMElement conversion as explained here:

That's true. But here, there's no attribute in his XML :) – Shikiryu Mar 07 '11 at 16:48
