Contactos PHP GMAIL Análisis XML con DOMDocument y cURL

Question

Lo que estoy tratando de obtener actualmente es solo el atributo de gd: email que es la "dirección =" nada más a partir del momento. Lo cual puedo llegar a la porción xml, diablos, incluso puedo obtener cualquier idea por decir, siempre y cuando esté dentro de las etiquetas, pero para obtener el atributo de cualquier dado como en mi caso ... Estoy completamente confundido. Solía ​​saber cómo hacerlo, pero ha pasado tanto tiempo desde que hice algo que no era simple para el uso de XML. por lo que la pata I hecho mi propio auto hasta ..

con el código que se parece (esto es el todo del guión (actualmente))

$user = "xxxxxxxxxxxxxxxxxxx@gmail.com"; 
$password = "xxxxxxxxxxxx"; 

// ref: http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html 

// step 1: login 
$login_url = "https://www.google.com/accounts/ClientLogin"; 
$fields = array(
    'Email' => $user, 
    'Passwd' => $password, 
    'service' => 'cp', // <== contact list service code 
    'source' => 'test-google-contact-grabber', 
    'accountType' => 'GOOGLE', 
); 

$curl = curl_init(); 
curl_setopt($curl, CURLOPT_URL,$login_url); 
curl_setopt($curl, CURLOPT_POST, 1); 
curl_setopt($curl, CURLOPT_POSTFIELDS,$fields); 
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
$result = curl_exec($curl); 

$returns = array(); 

foreach (explode("\n",$result) as $line) 
{ 
    $line = trim($line); 
    if (!$line) continue; 
    list($k,$v) = explode("=",$line,2); 

    $returns[$k] = $v; 
} 

curl_close($curl); 

// step 2: grab the contact list 
$feed_url = "http://www.google.com/m8/feeds/contacts/$user/full?&max-results=5"; 

$header = array(
    'Authorization: GoogleLogin auth=' . $returns['Auth'], 
); 

$curl = curl_init(); 
curl_setopt($curl, CURLOPT_URL, $feed_url); 
curl_setopt($curl, CURLOPT_HTTPHEADER, $header); 
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 

$result = curl_exec($curl); 
curl_close($curl); 

$doc = new DOMDocument(); 
$doc->load($result); 
$arrFeeds = array(); 
foreach ($doc->getElementsByTagName('entry') as $node) { 
    $monkey = $node->getAttribute('{gd:email}'); 
    $itemRSS = array($monkey->nodeValue); 
array_push($arrFeeds, $itemRSS); 
} 
array_unique($arrFeeds); 

Answer 1

Tenga una mirada en DOMDocument y DOMXPath. Para obtener nodos que forman parte de un espacio de nombre particular, como el nodo email que forma parte del espacio de nombres gd, debe registrar el espacio de nombres con el objeto DOMXPath utilizando DOMXPath::registerNamespace(). El URI del espacio de nombre generalmente se puede encontrar en la parte superior del documento XML.

Ejemplo:

$doc = new DOMDocument; 
$doc->recover = true; 
$doc->loadXML($result); 

$xpath = new DOMXPath($doc); 
$xpath->registerNamespace('gd', 'http://schemas.google.com/g/2005'); 

$emails = $xpath->query('//gd:email'); 

foreach ($emails as $email) 
{ 
    echo $email->getAttribute('address'); 

    // To get the title. 
    // This could also be done using XPath. 
    // You can also use ->nodeValue instead of ->textContent. 
    echo $email->parentNode->getElementsByTagName('title')->item(0)->textContent; 
} 

En el ejemplo anterior, $result es el resultado de $result = curl_exec($ch);.

Answer 2

$url = 'https://www.google.com/m8/feeds/contacts//full?max-results='.$max_results.'&oauth_token='.$accesstoken.'&alt=json&updated-min=2007-03-16T00:00:00'; 
function curl_file_get_contents($url) 
{ 

$curl = curl_init(); 
$userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)'; 
//The URL to fetch. This can also be set when initializing a session with curl_init(). 
curl_setopt($curl,CURLOPT_URL,$url);  
curl_setopt($curl, CURLOPT_HTTPHEADER,array('GData-Version: 2.0')); 
curl_setopt($curl,CURLOPT_RETURNTRANSFER,TRUE); //TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly. 
curl_setopt($curl,CURLOPT_CONNECTTIMEOUT,5); //The number of seconds to wait while trying to connect.  
curl_setopt($curl,CURLOPT_HTTPGET,true); 
curl_setopt($curl, CURLOPT_USERAGENT, $userAgent); //The contents of the "User-Agent: " header to be used in a HTTP request. 
//curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE); //To follow any "Location: " header that the server sends as part of the HTTP header. 
//curl_setopt($curl, CURLOPT_AUTOREFERER, TRUE); //To automatically set the Referer: field in requests where it follows a Location: redirect. 
curl_setopt($curl, CURLOPT_TIMEOUT, 10); //The maximum number of seconds to allow cURL functions to execute. 
//curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); //To stop cURL from verifying the peer's certificate. 

$contents = curl_exec($curl); 

curl_close($curl); 
return $contents;
