php - simplexml_load_string - 子节点不显示

Question

我正在处理一个 xml 文件，我试图将其解析为 json 格式，然后解码为一个数组。我主要使用内置的 simplexml_load_string 和 json_encode 来完成此操作。问题是在调用 simplexml_load_string 时，xml 未完全保留。 video 的子节点似乎显示为 object(stdClass)。我怎样才能获得 xml 文件的所有值？链接到 XML

代码:

$xml = simplexml_load_string( file_get_contents('http://foxsoccer2go.mobilefeeds.performgroup.com/fox/api/videos.xml/channel/home') );
$json = json_encode($xml);

结果:

["results"]=>
  object(stdClass)#183 (4) {
    ["previousPage"]=>
    object(stdClass)#184 (1) {
      ["@attributes"]=>
      object(stdClass)#185 (1) {
        ["exists"]=>
        string(5) "false"
      }
    }
    ["nextPage"]=>
    string(1) "2"
    ["total"]=>
    string(2) "40"
    ["resultList"]=>
    object(stdClass)#186 (1) {
      ["video"]=>
      array(20) {

          object(stdClass)#188 (2) {

            }

              ["@attributes"]=>
              object(stdClass)#194 (3) {

                ["uploaded"]=>
                string(4) "true"
              }
            }
          }
          ["categories"]=>
          object(stdClass)#198 (1) {

            string(21) "UEFA Champions League"
          }
        }

我建议只尝试单独使用 SimpleXML 来解析这些值并坚持下去。只需正确访问这些属性即可。对于那些已经用字符数据包裹的节点，将它们转换为(string)。

$xml = simplexml_load_string( file_get_contents('http://foxsoccer2go.mobilefeeds.performgroup.com/fox/api/videos.xml/channel/home'));
foreach($xml->results->resultList->video as $video) {
    $description = (string) $video->description;
    $created = $video->created;
    $duration = $video->duration;
    $image = $video->images->image;
    $thumbnail = (string) $video->images->image;
    $video_file = (string) $video->videoFiles->file;
    $categories = (string) $video->categories->category;

    echo "
    Description: $description <br/>
    Created: $created <br/>
    Duration: $duration <br/>
    Categories: $categories <br/>
    <hr/>
    ";
}
