Notepad ++正则表达式和替换

Question

I have a couple of sentences that need processing using regular expressions. They're in a text file and I'm opening it in notepad++.

<tag>There are two tags here</tag>
<tag>How am i supposed to
feel when this is happening?</tag>
<tag>I'm not sure.
But oh well<tag>

Is it possible to use notepad++'s regular expressions and replace functionality to produce an output like so:

<tag>There are two tags here</tag>
<tag>How am i supposed to feel when this is happening?</tag>
<tag>I'm not sure. But oh well<tag>

So that sentences that span over two or more lines are joined based on the fact that there is a > at the end of the sentence. Thanks.

[\r\n]+(?!<)

• (?!<) - negative lookahead to validate that the above match is not followed by an opening tag <
