SimpleXML Question

[N-Bomb(Nerd)]

Hi, I'm new to SimpleXML and I'm trying to learn.

 

I'm trying to figure out how to delete a child ( and all sub-children ), however I'm not doing very good.

 

Was hoping someone could explain to me what I'm doing wrong..

 

test.xml:

<?xml version="1.0" encoding="ISO-8859-1"?>
<man>
<phone company="verizon">
	<r>empty</r>
</phone>

<phone company="att">
	<r>empty</r>
</phone>

<phone>
	<r>empty</r>
</phone>
</man>

 

test.php

$phones = array("verizon");
$xml = simplexml_load_file('test.xml');

foreach ($xml as $phone) {
if (in_array((string) $phone['company'], $phones)) {
	unset($xml->$phone);
}
}

print_r($xml);

 

As you can see the phone with the company = "verizon" is still in the xml.. how do I get it to remove?

 

Thanks

your loop should be

 

for ($i=0;$i<count($xml->phone);$i++) {
    if (in_array((string) $xml->phone[$i]['company'], $phones)) {
        unset($xml->phone[$i]);
    }
}
