用於獲取Javascript標記中的數據的HTML源代碼

Question

我試圖獲取網頁的HTML源代碼，然後用它來獲取Javascript標記中的數據。

頁面上的JavaScript代碼是這樣的：

<script> 
fullplayer("player", { 
      src:"full_width_player.swf", 
      wmode:"window" 
     }, { 
    key: '#$0c4de1874473849ff8a', 
    canvas: { 
     backgroundGradient: "none", 
     backgroundColor: "#000000" 
    }, 
    audio: { 
     provider: 'servstat', 
     q: '128' 
    }, 
    playlist: '/get.php?location=/audio/welcome.mp3', 
    plugins: { 
     youtube: { } 
    } 
}); 
</script> 

我正在尋找一種方式來獲得內部playlist:'*****',值，這意味着音軌的位置 - /get.php?location=/audio/welcome.mp3

這是可能與HTML DOM短語，或者我需要抓住JavaScript標籤內的整個東西，並讀取數據爲XML或類似的東西？

嘗試，這是一個正則表達式

preg_match_all('~playlist:[ ]*[\'|"](.*?)[\'|"]~si',$HTML,$Match); 
print_r($Match); 

輸出爲您的樣品：

Array 
(
    [0] => Array 
    (
     [0] => playlist: '/get.php?location=/audio/welcome.mp3' 
    ) 

    [1] => Array 
    (
     [0] => /get.php?location=/audio/welcome.mp3 
    ) 

)
