在vim下怎么复制正则表达式匹配的内容？

[PeterD]

比如，我想复制下面所有的 <p>.*</p>

anything google <p>this is sentence 1.</p>
anything git <p>this is sentence 2.</p>
anything py <p>this is sentence 3.</p>
this is a break.
anything v2ex <p>this is sentence 4.</p>

复制的输出要是：

<p>this is sentence 1.</p>
<p>this is sentence 2.</p>
<p>this is sentence 3.</p>
<p>this is sentence n.</p>

------------
有什么命令可以解决吗？
