這里我們使用XMLReader擴展來解析和處理該文件，XMLReader還有一個好處是以Stream的形式讀取數(shù)據(jù)，即縱然面對超大的xml文件依然可以從容處理。下面是我們針對以上文件的處理方式：

復(fù)制代碼代碼如下:

$indexUrl='http://www.xxx.com/xxx.xml';   

$reader = new XMLReader();   

$reader->open($indexUrl);   

$countElements = 0;   

while ($reader->read()){   

        if($reader->nodeType == XMLReader::ELEMENT){   

            $nodeName = $reader->name;   

        }   

        if($reader->nodeType == XMLReader::TEXT && !empty($nodeName)){   

            switch($nodeName){   

                case 'name':   

                    $name = $reader->value;   

                    break;   

                case 'channel':   

                    $channel = $reader->value;   

                    break;   

                case 'start':   

                    $start = $reader->value;   

                    break;   

                case 'duration':   

                    $duration = $reader->value;   

                    break;   

            }   

        }   

 }   

$reader->close();
