The following steps show you how to grab a feed using Zend Framework's GData package and then grab the appropriate values.
PHP:
-
//Initiate an authorised http client
-
//See previous post on how to get an auth token and convert it to a session token
-
$client = Zend_Gdata_AuthSub::getHttpClient($authToken);
-
-
//Instantiate a new GData Calendar instance + set the identifiers and parameters
-
$gdata_cal = new Zend_Gdata_Calendar($client);
-
$gdata_cal->setUser('vinoajtest@gmail.com');
-
$gdata_cal->setVisibility('private');
-
$gdata_cal->setProjection('full');
-
-
//Returns an atom feed object represented by Zend_Feed_Atom
-
//The Zend_Feed_Atom object is an extension of DOMDocument
-
//Call Zend_Feed_Atom::saveXML() to acquire a fully-formed DOMDocument at any time
-
$gdata_cal_feed = $gdata_cal->getCalendarFeed();
-
-
//Let's spit out some basic FEED information
-
$n_entries = $gdata_cal_feed->count(); //int
-
$feed_title = $gdata_cal_feed->title(); //str
-
$feed_id = $gdata_cal_feed->id(); //str url
-
-
$feed_links = $gdata_cal_feed->link(); //array links
-
foreach ($feed_links as $ix => $link){
-
//Each item is of type DOMElement
-
$link_rel = $link->getAttribute('rel');
-
$link_type = $link->getAttribute('type');
-
$link_href = $link->getAttribute('href');
-
}
-
-
$feed_subtitle = $gdata_cal_feed->subtitle(); //Equivalent to a RSS' channel description
-
$feed_author_name = $gdata_cal_feed->author->name(); //str
-
$feed_author_email = $gdata_cal_feed->author->email(); //str email
-
-
//Now lets's spit out ENTRIES and their information
-
foreach ($gdata_cal_feed as $ix => $cal_entry){
-
$cal_entry_id = $cal_entry->id(); //str url

//category

-
$cal_entry_category_dom = $cal_entry_category->getDOM(); //Convert it to a DOM element so we can read off the attributes
