Question

可能重复:
PHP Curl,提取XML响应

如何用curl php解析器xml？这是我的代码,如何获取xml每个项目的值？谢谢.

<?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

CURL与XML无关,它只是一种为您检索XML的交付机制.这就像说牛奶味道不同,因为一个送货司机使用汽车而一个人使用卡车.

要在PHP中处理XML,请使用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

您只需将结果加载到SimpleXML数据中并循环遍历数据即可.这是一个例子:

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";
    }
  }
}

这是一些示例输出:

$ php test.php
