我正在尝试获取网页的 HTML 源代码,然后对其进行表述以获取 Javascript 标记内的数据。

该页面上的 Javascript 标记如下所示:

<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>

我正在寻找一种方法来获取其中的值,playlist:'*****',这意味着音轨的位置-/get.php?location=/audio/welcome.mp3

这是否可以使用 HTML DOM 短语,还是我需要抓取 Javascript 标记内的所有内容并将数据读取为 XML 或类似的东西?

试试这是一个正则表达式

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

样品的输出:

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

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

 )
