PHP Remove Element from XML

Question

I want to remove tasks that are older than today, but I can\'t quite figure out how to remove elements from XML file yet.

$xml_file = simplexml_load_file(\'file.

It's actually very tricky. You have to unset() the appropriate variable, but it needs to be a reference to the parent node (i.e., unset($aTask) will not work). Additionally, if you do foreach ($xml_file->task as $index => $aTask) to keep track of the child position, you'll get task in every iteration!

You need some ugly code like this:

$index = 0;
$remove = array();
foreach ($xml_file->task as $aTask) {
    if ($aTask->date < $today) {
        $remove[] = $index;
    }
    $index++;
}

foreach($remove as $index){
    unset($xml_file->task[0]);
}

P.S. As already noted, your date handling routines do not work.

Edit: I've actually tried my own code and it works, so downvoter should explain himself.
