PHP SimpleXML Namespace Problem

Question

I\'m trying to get the entry->id and entry->cap:parameter->value for every entry in the RSS feed.... below is the code I\'m using. It is displaying the id correctly however

Answer 1

The element is not in the same namespace as :

    VTEC
    /O.CON.KMPX.FL.W.0012.000000T0000Z-110517T1800Z/

So you have to call children() again.

Code (demo)

$feed = simplexml_load_file('http://alerts.weather.gov/cap/us.php?x=1');
foreach ($feed->entry as $entry){
    printf(
        "ID: %s\nVTEC: %s\n
",
        $entry->id,
        $entry->children('cap', true)->parameter->children()->value
    );
}
