Question

我正在使用xml文件，我尝试将其解析为json格式，然后解码为数组。我主要使用内置的simplexml_load_string然后json_encode完成了这项工作。问题是在调用simplexml_load_string时，xml未完全保留。似乎video的子节点显示为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) {

我建议只尝试使用SimpleXML解析这些值并坚持使用它。只需正确访问这些属性。对于那些已包含字符数据的节点，将其转换为(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/>
    ";
}

Sample Output

simplexml_load_string - 未显示的子节点
