Php 如何将以下XML数据转换为数组（JSON或其他格式）

虽然有很多将“普通”XML转换成数组的选项，但我非常希望找到一种方法，将这些数据转换成一个可以用PHP处理的数组（目前设计为由JQuery处理）

这个xml字符串中还有大约99个对象，因此为了简单起见，我只包含了1个

---

我想把数组转换成JSON或PHP数组——谢谢：）

不要。只需在DOM上使用Xpath来获取部分，在您的例子中是CDATA部分中的JSON结构

该结构不是真正的JSON，而是Javascript，缺少属性名称周围的引号。这是PHP手册中一个很好的正则表达式，可以修复它

$xml = <<<'XML'
<?xml version="1.0" encoding="ISO-8859-15"?><root><data><![CDATA[ [{title_id: "284270",
          track_id: "1548617",
          artist: [[20670, 1, "Matthias Vogt", "matthias-vogt"]],
          title: "The Wobble Track",
          title_url: "/title/284270/the-wobble-track",
          track_url: "/track/1548617/the-wobble-track",
          label: [88, "Large Music", "large-music"],
          genre: "Deep House",
          genre_url: "/genre/13/deep-house",
          catnumber: "LAR181",
          promo: false,
          duration: "5:54",
          r_date: "2014-02-17",
          price: {hbr: 1.99, wav: 2.74},
          bought: false,
          image: "http://static.traxsource.com/files/images/271306_large.jpg",
          thumb: "http://static.traxsource.com/scripts/image.php/44x44/271306.jpg",
          mp3: "http://preview.traxsource.com/files/previews/88/1324290-p.mp3",
          waveform: "http://static.traxsource.com/files/wf/1324290-wf.png",
          bpm: "120",
          keysig: "Bmin"}
] ]]></data></root>
XML;

function javascript_decode($json, $assoc = FALSE){
  $json = str_replace(array("\n","\r"),"",$json);
  $json = preg_replace('(([{,]+)(\s*)([^"]+?)\s*:)','$1"$3":',$json);
  return json_decode($json,$assoc);
} 

$dom = new DOMDocument();
//$dom->load($xmlFile);
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);

$json = javascript_decode($xpath->evaluate('string(/root/data)'));
var_dump($json);

---

考虑到我无法用任何解决方案解决问题，我继续挖掘并做了一些测试。我的解决方案并不漂亮，但肯定很实用。 我删除了所有XML数据，留下了相当原始的JSON。在本例中，JSON数据的问题是字符串没有包装在“”中，所以我做了一个str_替换来修复这个问题，并且一切正常。 $content=str_replace（“”，“，”，str_replace（“\”，“'”，$content））

---

然后我就可以循环并正常处理了。

谢谢，但是var_dump只给了我NULL，我是否遗漏了什么？如果没有加载XML，或者JSON无效，可能会发生这种情况。我编辑了答案，并添加了示例数据和一个实时链接。你能用我问题中包含的实际数据来实现这一点吗？还是数据格式不正确？如果没有，那么你对如何解决我的问题有什么想法吗？不完整的问题？不，当然JSON不能被解码，它是不完整的。XML阅读部分对它起作用，但是：好的，但是我仍然不清楚您的答案如何解决我遇到的问题。。。？
