Query XML with variable using PHP

Question

I've started parsing XML with PHP and got stuck with this problem. I've managed to query the XML with the following method:

echo $xml->textbox->item->id;

What's the syntax to use a variable instead of textbox?

I've tried (but didn't work):

echo $xml[$type]->item->id;
echo $xml->[$type]->item->id;

Any ideas?

$xml->{$variable}->item->id

will work. You may want to check first whether that path exists, e.g. using empty().

thanks - this works! i forgot to ask something else: how to put the variable inside the for each loop? foreach($xml as {$type]) doesnt work .. :(

@Fuxi to be honest, I'm not entirely sure: XML nodes have their own structure. Try to see what comes out of foreach ($xml as $key => $value) - see what $key and $value contain
