i trying value of temperature

echo '<b>temperature:</b> '. $xml->forecast->children('temperature')->attributes('value'); 

this im stuck

i appreciate answers :)

to value attribute of first occurence of temperature node, do:

$result = $xml->forecast[0]->time[0]->temperature["value"]; 

to take <time> account, use xpath:

$results = $xml->xpath("//time"); 

this select time nodes, loop:

foreach ($results $result)     echo "temperature $result[from] $result[to]: {$result->temperature['value']}<br />";
