PHP GMAIL Contact Us XML Parsing with DOMDocument and cURL

Question

What I'm trying to get at the moment is just the gd: email attribute, which is "address =", only from the moment it appears. Which I can get in the xml part, damn it, I can even get any given opinion for everyone, as long as I like it inside the tags, but get the attribute of any given, as in my case. I am completely confused. I used to know how to do this, but for so long I did everything that was not easy to use XML. so I ruined everything for myself.

with code that looks like (this is a whole script (currently))

 $user = " [e-mail] "; $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

See DOMDocument and DOMXPath . In order to get nodes that are part of a specific namespace, for example email node, which is part of the gd namespace, you need to register a namespace with a DOMXPath object using DOMXPath::registerNamespace() . Namespace URIs can usually be found at the top of an XML document.

Example:

 $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; } 

In the above example, $result is the result of $result = curl_exec($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 certificate. $contents = curl_exec($curl); curl_close($curl); return $contents; }
