    Google 查到的都是无效或者不是想要的

    要求可以匹配 magnet:?xt=urn:btih:D2360003C0040BC98A6D9C4A136522FBE7FCAFFA 短的

    也可以匹配后面跟一大堆的如 magnet:?xt=urn:btih:8AC3731AD4B039C05000B5404AFA6E7397810B41&dn=ubuntu+11+10+oneiric+ocelot+desktop+cd+i386&tr=http%3A%2F%2Ftracker.openbittorrent.com%2



    PS.都是无效地址 ////

    @line
    然而HASH值0-9A-F，就不会有G-Z
    ^(magnet:\?xt=urn:btih:)[0-9a-fA-F]{40}.*$

    @popok 没有具体了解过去，楼主只是求个正则而已。感谢你，让我又学到一个知识。

    @ChoateYao 其实想想电脑中很多都是十六进制，就知道了啦。
