PHP GMAIL Contacts XML Parsing with DOMDocument and cURL - php

Question

What I am trying to get currently is just the attribute of gd:email that is the "address=" only nothing else as of the moment. Which I can get to the xml portion, heck I can even get any given think per say as long as its within tags like but to get the attribute of any given one like in my case.. I am completely confused on. I used to know how to do it but its been so long since I did anything that wasn't simple for XML useage. so I done messed my own self up..

Answer 1

Have a look at DOMDocument and DOMXPath. In order to get nodes that are part of a particular namespace, like the email node which is part of the gd namespace, you need to register the namespace with the DOMXPath object using DOMXPath::registerNamespace(). The namespace URI can usually be found at the top of the 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 example above, $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's certificate.
$contents = curl_exec($curl);
curl_close($curl);
return $contents;
