Count number of rows XML?

[Oskare100]

Hello,
I need to be able to count the number of rows that an XML response contains, here is the code that receives the XML response:

$request = file_get_contents($request_url) or die("feed not loading");
{
    $xml = new SimpleXMLElement( $request );
    foreach ( $xml->data_list->data->agent_list->agent as $agent )
    {
        echo
            ( string ) $agent['index'], "\n",
            ( string ) ucwords(strtolower(utf8_decode($agent->name))), "\n",
            ( string ) ucwords(strtolower(utf8_decode($agent->address))), "\n",
            ( string ) ucwords(strtolower(utf8_decode($agent->address2))), "\n",
            ( string ) ucwords(strtolower(utf8_decode($agent->zipcode))), "\n",
            ( string ) ucwords(strtolower(utf8_decode($agent->city))), "\n",
            ( string ) $agent->agent_number, "\n",
            "<p>";    

    }
}

Now, I want to be able to count the number of agents (the number of returned arrays or what it is called, the number of times it will loop). How can I do that?

You could just stick in some sort of counter variable and increment it.

$counter = 0;
foreach(blah...blah...blah)
{
   $counter++;
   // rest of loop....
}
echo "You looped $counter times.";

Wouldn't it just be count($xml->data_list->data->agent_list->agent)? Or is $xml->data_list->data itself an array that needs to be iterated over as well?
