我一直尝试使用其他方法从HTML表中提取数据，例如使用xpath。该表不包含任何类，因此我不确定如何在没有类或ID的情况下使用xpath。正在从rss xml文件中检索此数据。我目前正在使用DOM。提取数据后，我将尝试按职位对表格进行排序

这是我的PHP代码

$html='';
$xml= simplexml_load_file($url) or die("ERROR: Cannot connect to url\n check if report still exist in the Gradleaders system");

/*What we do here in this loop is retrieve all content inside the encoded content, 
*which includes the CDATA information. This is where the HTML and styling is included.
*/

foreach($xml->channel->item as $cont){
    $html=''.$cont->children('content',true)->encoded.'<br>';   //actual tag name is encoded 
}

$htmlParser= new DOMDocument();     //to parse html using DOMDocument
libxml_use_internal_errors(true);   // your HTML gives parser warnings, keep them internal
$htmlParser->loadHTML($html); …

所以我很难找到我的代码中哪里出了问题。我正在构建音频播放器。该功能无法找到我的设备中除2个文件以外的所有音频文件。我认为问题可能出在我的歌曲定位算法findSongs中。
