要提取出 (只要这个镜像的链接)

http://11.bak.115cdn.com:8080/pickdown/7285214fb5739ab16a77acece4e5b6c54c1857f4/M00/26/E3/d5Nq-UvUR4kAAAAALuAAACzdBM43460900/%E9%98%BF%E5%87%A1%E8%BE%BE.Avatar.2009.BD.2Audio.MiniHD-TLF.part1.rar?file=%E9%98%BF%E5%87%A1%E8%BE%BE.Avatar.2009.BD.2Audio.MiniHD-TLF.part1.rar&key1=4c182dc4&key2=3230332e3132362e35362e36

用RegexBuddy研究了一下,如下表达式可以匹配出结果(RegexBuddy测试成功,兼容语法为perl)

http://\.bak\.115cdn\.com:8080/pickdown.*?(?=")

修改一下复制到cmd命令行中测试.

sed "/http:\/\/\.bak\.115cdn\.com:8080\/pickdown.*?(?=")" text.htm

出现如下语法错误:

sed: -e expression #1, char 70: unterminated address regex

测试过的sed版本包括GNU sed version 4.1.5(含cygwin1.dll的版本) 和GNU sed version 4.2(gnuwin32.sourceforge.net版本,含pcre3.dll-Perl-compatible regular-expression library).

请问正确的语法应该怎样写? 如果上述表达式有sed不支持的参数,应该如何改写(或更好的写法)?

谢谢
