[XML] XML格式【有道翻译】API 的数据转化输出

<?php
header("content-type:text/html;charset=utf-8");
//echo "飞飞仔超级智障";
$content= "When there is no desire, all things are at peace. - Laozi";

$url = "http://fanyi.youdao.com/openapi.do?keyfrom=keyform&key=key&type=data&doctype=xml&version=1.1&q=".$content;  

$list = file_get_contents($url);
//xpath方法解析xml
$dom = new DOMDocument('1.0','utf-8');

$dom->loadXML($list);

$xpath = new DOMXPath($dom);

$path = '/youdao-fanyi/translation/paragraph';    //要查询的节点路径

var_dump($xpath->query($path)->item(0)->nodeValue);



die;

这是我获得一个翻译接口的数据转化，还是XML的好获取转化！

得到的结果是：

string(52) "当没有欲望,一切都是和平的。——老子"
