用 DOM API 解析 Google Calendar 事件摘要

<?php $confirmed = 'http://schemas.google.com/g/2010#event.confirmed'; $three_months_in_seconds = 60 * 60 * 24 * 28 * 3; $three_months_ago = date("Y-m-d\Th:i:sP", time() - $three_months_in_seconds); $three_months_from_today = date("Y-m-d\Th:i:sP", time() + $three_months_in_seconds); $feed = "http://www.google.com/calendar/feeds/xx%40gmail.com/" . "public/full?orderby=starttime&singleevents=true&" . "start-min=" . $three_months_ago . "&" . "start-max=" . $three_months_from_today; $doc = new DOMDocument(); $doc->load( $feed ); $entries = $doc->getElementsByTagName( "entry" ); foreach ( $entries as $entry ) { $status = $entry->getElementsByTagName( "eventStatus" ); $eventStatus = $status->item(0)->getAttributeNode("value")->value; if ($eventStatus == $confirmed) { $titles = $entry->getElementsByTagName( "title" ); $title = $titles->item(0)->nodeValue; $times = $entry->getElementsByTagName( "when" ); $startTime = $times->item(0)->getAttributeNode("startTime")->value; $when = date( "l jS \o\f F Y - h:i A", strtotime( $startTime ) ); $places = $entry->getElementsByTagName( "where" ); $where = $places->item(0)->getAttributeNode("valueString")->value; print $title . "\n"; print $when . " AST\n"; print $where . "\n"; print "\n"; } } ?>

用 SAX API 解析 Google Calendar 事件摘要

function startElement( $parser, $tagName, $attr ) { global $g_entries, $g_tagName, $g_confirmed, $g_is_confirmed, $g_in_entry, $g_in_originalevent; if ( $tagName == 'ENTRY' ) { if ($g_is_confirmed || count( $g_entries ) == 0) { $g_entries []= array(); } $g_is_confirmed = false; $g_in_entry = true; } else if ($tagName == 'GD:EVENTSTATUS') { if ($attr['VALUE'] == $g_confirmed) { $g_is_confirmed = true; } } else if ($tagName == 'GD:WHEN' && $g_is_confirmed && $g_in_originalevent == false) { $startTime = date( "l jS \o\f F Y - h:i A", strtotime($attr['STARTTIME']) ); $g_entries[ count( $g_entries ) - 1 ]['when'] = $startTime; } else if ($tagName == 'GD:WHERE' && $g_is_confirmed) { $g_entries[ count( $g_entries ) - 1 ]['where'] = $attr['VALUESTRING']; } else if ( $tagName == 'GD:ORIGINALEVENT' ) { $g_in_originalevent = true; } $g_tagName = $tagName; } function endElement( $parser, $tagName ) { global $g_tagName, $g_in_entry, $g_in_originalevent; if ( $tagName == 'ENTRY' ) { $g_in_entry = false; } else if ( $tagName == 'GD:ORIGINALEVENT' ) { $g_in_originalevent = false; } $g_tagName = null; } function textData( $parser, $text ) { global $g_entries, $g_tagName, $g_in_entry; if ($g_tagName == 'TITLE' && $g_in_entry) { $g_entries[ count( $g_entries ) - 1 ]['title'] = $text; } }

用 Zend PHP 类请求和处理 Google Calendar 事件摘要

<?php require_once 'Zend/Loader.php'; Zend_Loader::loadClass('Zend_Gdata'); Zend_Loader::loadClass('Zend_Gdata_Calendar'); $three_months_in_seconds = 60 * 60 * 24 * 28 * 3; $three_months_ago = date("Y-m-d\Th:i:sP", time() - $three_months_in_seconds); $three_months_from_today = date("Y-m-d\Th:i:sP", time() + $three_months_in_seconds); // Create an instance of the Calendar service without authentication, // for read-only access to a public feed $service = new Zend_Gdata_Calendar(); $query = $service->newEventQuery(); $query->setUser(xx%40gmail.com'); $query->setVisibility('public'); $query->setProjection('full'); $query->setOrderby('starttime'); $query->setStartMin($three_months_ago); $query->setStartMax($three_months_from_today); // Retrieve the event list from the calendar server try { $eventFeed = $service->getCalendarEventFeed($query); } catch (Zend_Gdata_App_Exception $e) { echo "Error: " . $e->getResponse(); } // Iterate through the list of events, outputting them as an HTML list print "<ul>\n"; foreach ($eventFeed as $event) { print "<li>" . $event->title . "</li>\n"; $startTime = $event->when->startTime; print "<li>" . date("l jS \o\f F Y - h:i A", strtotime( $startTime ) ); // Google Calendar API's support of timezones is buggy print " AST</li>\n"; print "<li>" . $event->where->valueString . "</li>\n"; }   print "</ul>\n";

用 XPath 和 SimpleXML 解析 Google Calendar 事件摘要

$s = simplexml_load_file($feed); foreach ($s->entry as $item) { $gd = $item->children('http://schemas.google.com/g/2010'); if ($gd->eventStatus->attributes()->value == $confirmed) { ?> <font size=+1><b> <?php print $item->title; ?> </b></font><br> <?php $startTime = ''; if ( $gd->when ) { $startTime = $gd->when->attributes()->startTime; } elseif ( $gd->recurrence ) { $startTime = $gd->recurrence->when->attributes()->startTime; } print date("l jS \o\f F Y - h:i A", strtotime( $startTime ) ); // Google Calendar API's support of timezones is buggy print " AST<br>"; ?> <?php print $gd->where->attributes()->valueString; ?> <br><br> <?php } } ?>
