XML looping

[Vince889]

Take a look here:

http://answers.yahooapis.com/AnswersService/V1/questionSearch?appid=YahooDemo&query=test

 

That is a generated XML file from Yahoo's API. If you take a look, it has a node titled "Question". With PHP, how can I loop through each "Question" node and grab all of it's children as well?

 

I tried this code, but apparently it did not work:

 

$req = "http://answers.yahooapis.com/AnswersService/V1/questionSearch?appid=YahooDemo&query=php";
$res = file_get_contents($req);
$xml = simplexml_load_string($res);

foreach ($xml->xpath('//Question') as $question) { // "//question" means for each question node
  echo((string)$question['Subject']." - ".(string)$question['Content']); // you get all the child nodes in $question
}

Not sure exactly what you're trying to do.  But if you want to loop through each question and all of its children then you can use something like:

 

ini_set ("display_errors", "1"); 
error_reporting(E_ALL);

$req = "http://answers.yahooapis.com/AnswersService/V1/questionSearch?appid=YahooDemo&query=php";
$res = file_get_contents($req);
$xml = simplexml_load_string($res);

foreach ($xml->xpath('/ResultSet/Question') as $question) 
{ // "//question" means for each question node
   foreach($question->children() as $name => $child)
   {   
      echo $name . "\n" . $child; // you get all the child nodes in $question
   }   
} 

?>

 

You may also want to write a cron job that collects the XML and stores it locally so it doesn't take as long to load the contents.
