“不许联想”mp3player.xml处理

johncan

今天想去下载王小峰博客上的音乐，像往常一样，把http://www.wangxiaofeng.net/mp3player.xml拉回来，发现格式都乱了，像以下，只有2行（<player ×××>到</player>为一行）。

<?xml version="1.0" encoding="UTF-8"?>

想过将http与mp3之间的内容提取出来，但不知道如何入手，最后想出先将它分行，再提出mp3地址

sed "s/<song/\n\r<song/g" mp3player.xml |cut -d\" -f2

输出,有首歌的歌名不是英文，乱码了，Andres_Cepeda-Faltar¨￠n.mp3
http://music.u148.net/Kris_Kristofferson-holy_woman.mp3

能不能不分行，然后直接把http与mp3之间的内容提取出来呢？

lucash

grep -oP '(?<=song path=")[^"]*(?=" title=)' mp3.xml

为什么是非"字符？http后跟的是://啊，想不明白
还请黑哥再解释下！

blackold

://都不是"啊，这就对了。

如果想深入了解，先看正则基础吧，看过你就明白了。
