[RESOLVED] Removing particular XML elements with SimpleXML

Hello everyone.

I am trying to edit an element on a XML file with SimpleXML, and as far as I am concerned I have to remove the old one and then add the new one. First of all, my XML file is like this:

Code:

---

<?xml version="1.0" encoding="UTF-8"?>
<Document>
<Placemark id="1000"><!-- children elements --></Placemark>
<Placemark id="1001"><!-- children elements --></Placemark>
<Placemark id="1002"><!-- children elements --></Placemark>
...
</Document>

---

I load the XML like this:

PHP Code:

---

$xmlfile= 'universities.xml';
$xml = simplexml_load_file($xmlfile) or die("Αρχείο XML δε βρέθηκε");
$institutions=$xml->children(); 


---

Now i find the <Placemark> element with the id attribute I want like this:

PHP Code:

---

foreach ($institutions as $institution)  {
if ($institution['id']==$id) {
$current_uni = $institution;
}
} 


---

What do I have to do to remove this particular element?

Thank you in advanced. :)

No worries, got it. Found out that I had to use DOM, simpleXML does not remove stuff.

Just for anyone interested:

PHP Code:

---

$id = $_POST["id"];

foreach($xml->Placemark as $uni)
{
    if($uni['id'] == $id) {
        $dom=dom_import_simplexml($uni);
        $dom->parentNode->removeChild($dom);
    }
}
if (($xml->asXml($xmlfile)) == 1)
    echo 'All good';
else
    echo 'Woopsie, try again';
