sed 搜索并替换为 2 conditions/patterns

Question

我有一个文件：

<a href="http://www.gnu.org/software/coreutils/">http://www.gnu.org/software/coreutils/</a>
<a href="../../3/glob.html" rel="nofollow">glob</a>
<a href="lxc-ls.html" rel="nofollow">lxc-ls</a>

我只需要替换下面：

<a href="lxc-ls.html" rel="nofollow">lxc-ls</a>

与

<a href="../lxc-ls.html" rel="nofollow">lxc-ls</a>

lxc-ls 可以是任何单词，因为我在需要替换的多个文件中有多个这样的链接。

我不想对其他 2 个链接进行任何更改。即

<a href="http://www.gnu.org/software/coreutils/">http://www.gnu.org/software/coreutils/</a>
<a href="../../3/glob.html" rel="nofollow">glob</a>

我尝试过的是：

$ sed '/html/ i\
..' file

但这附加到行首，另外排除2个URL的其他条件也没有填满。

这是来自其中一个文件的更真实的示例。

<b><a href="../../1/echoping.html" rel="nofollow">echoping</a></b>(1),
<b><a href="../../3/getaddrinfo.html" rel="nofollow">getaddrinfo</a></b>(3),
<b><a href="../../3/getaddrinfo_a.html" rel="nofollow">getaddrinfo_a</a></b>(3),
<b><a href="../../2/getpeername.html" rel="nofollow">getpeername</a></b>(2),
<b><a href="../../2/getsockname.html" rel="nofollow">getsockname</a></b>(2),
<b><a href="../../3/ping_setopt.html" rel="nofollow">ping_setopt</a></b>(3),
<b><a href="../../5/proc.html" rel="nofollow">proc</a></b>(5),
<b><a href="rds.html" rel="nofollow">rds</a></b>(7),
<b><a href="../../2/recv.html" rel="nofollow">recv</a></b>(2),
<b><a href="rtnetlink.html" rel="nofollow">rtnetlink</a></b>(7),
<b><a href="sctp.html" rel="nofollow">sctp</a></b>(7),
<b><a href="../../3/sctp_connectx.html" rel="nofollow">sctp_connectx</a></b>(3),
<b><a href="../../2/send.html" rel="nofollow">send</a></b>(2),
<b><a href="udplite.html" rel="nofollow">udplite</a></b>(7)
<a href="http://gnu.org/licenses/gpl.html">http://gnu.org/licenses/gpl.html</a>
<a href="http://translationproject.org/team/">http://translationproject.org/team/</a>

这里我只需要替换：

<b><a href="rds.html" rel="nofollow">rds</a></b>(7),
<b><a href="rtnetlink.html" rel="nofollow">rtnetlink</a></b>(7),
<b><a href="sctp.html" rel="nofollow">sctp</a></b>(7),
<b><a href="udplite.html" rel="nofollow">udplite</a></b>(7)

与：

<b><a href="../rds.html" rel="nofollow">rds</a></b>(7),
<b><a href="../rtnetlink.html" rel="nofollow">rtnetlink</a></b>(7),
<b><a href="../sctp.html" rel="nofollow">sctp</a></b>(7),
<b><a href="../udplite.html" rel="nofollow">udplite</a></b>(7)
