如何使用curl進行php解析器xml？這裏是我的代碼，如何獲取xml每個項目的值？謝謝。

<?php 
define("EMAIL_ADDRESS", "youlichika@hotmail.com"); 
$ch = curl_init(); 
$cv = curl_version(); 
$user_agent = "curl ${cv['version']} (${cv['host']}) libcurl/${cv['version']} ${cv['ssl_version']} zlib/${cv['libz_version']} <" . EMAIL_ADDRESS . ">"; 
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent); 
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt"); 
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); 
curl_setopt($ch, CURLOPT_ENCODING, "deflate, gzip, identity"); 
curl_setopt($ch, CURLOPT_HEADER, FALSE); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_HTTPGET, TRUE); 
curl_setopt($ch, CURLOPT_URL, "http://en.wikipedia.org/w/api.php?action=opensearch&search=tokyo&format=xml&limit=2"); 
$xml = curl_exec($ch); 
curl_close($ch); 
var_dump($xml); 
?>

Answer 1

捲曲無關與XML，它只是一個傳遞機制，爲你檢索XML。這就像說牛奶的味道不同，因爲一個送貨司機使用汽車，一個使用卡車。

在PHP中處理XML，使用DOM或SimpleXML

$dom = new DOMDocument(); 
$dom->loadXML($xml); // where $xml is the result from curl 
... do whatever you want with the DOM object here ... 

Answer 2

您可以將結果只加載到SimpleXML和環比數據。這裏有一個例子：

define("EMAIL_ADDRESS", "youlichika@hotmail.com"); 
$ch = curl_init(); 
$cv = curl_version(); 
$user_agent = "curl ${cv['version']} (${cv['host']}) libcurl/${cv['version']} ${cv['ssl_version']} zlib/${cv['libz_version']} <" . EMAIL_ADDRESS . ">"; 
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent); 
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt"); 
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); 
curl_setopt($ch, CURLOPT_ENCODING, "deflate, gzip, identity"); 
curl_setopt($ch, CURLOPT_HEADER, FALSE); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_HTTPGET, TRUE); 
curl_setopt($ch, CURLOPT_URL, "http://en.wikipedia.org/w/api.php?action=opensearch&search=tokyo&format=xml&limit=2"); 
$xml_data = curl_exec($ch); 
curl_close($ch); 

// Make sure we actually have something to parse 
if($xml_data) { 
    $parser = simplexml_load_string($xml_data); 

    foreach($parser->Section as $section) { 
    foreach($section->Item as $item) { 
     echo "{$item->Text}\n\n{$item->Description}\n--------------------\n"; 
    } 
    } 
} 

下面是一些示例輸出：[！從來沒有人問過這個]
