How do I loop through multiple child nodes of XML?

Question

I am having some trouble trying to loop through an XML document. The XML looks like this:

My code (below) whilst it loops through all 'weather' nodes, it only picks out the first 'hourly' child node and completely skips the second. Would someone be able to help me as if I am honest, I do not know enough about looping to fix it and its driving me nuts! Grr.

Here is my PHP code which loads an XML document from online and then formats the XML results into div tags and obviously loops through the XML but as I said only loops through the first 'hourly' node of each 'weather' node.


    
Time
    
Temp C
    
Temp F
    
Wind Speed MPH
    
Wind Speed KMPH

EOF;
foreach($data as $weather) // loop through our hours
{
echo <<
        
{$weather->time}
        
{$weather->tempC}
        
{$weather->tempF}
        
{$weather->hourly->windspeedMiles}
        
{$weather->hourly->windspeedKmph}
EOF;
}
echo    '';
?>

EDITED CODE:

$str = "";
foreach($data->weather as $weather)
{
    foreach ($weather->hourly as $hour)
    {
        $str .= "
    ";

        if ($hour->time == "0") {
            $str .= "
        
$weather->date
        
$weather->maxtempC
        
$weather->mintempC";
        }

        $str .= "
        
$hour->time
        
$hour->tempC
        
$hour->tempF
        
$hour->windspeedMiles
        
$hour->windspeedKmph
    
    ";
    }
}
echo $str;

Using a slenderized version of your XML feed, that generates this:
