How can I change one or more line breaks to something in ruby?
如何将一个或多个换行符更改为ruby中的某些内容？
article.content.gsub(/\n/, "<br />")
above code will change every 1 line break to <br /> tag, however, I want to change one or more \n to <br /> tag. In that way, continuous line breaks with empty lines will be substitued into a single <br /> tag. How can I do that?
上面的代码会将每1行中断更改为
标记，但是，我想将一个或多个\ n更改为
标记。这样，带有空行的连续换行将被替换为单个
标签。我怎样才能做到这一点？

article.content.gsub(/\n+/, "<br />")
Note the plus sign after the \n. That will change any sequence of one or more newlines to a single <br>.
注意\ n后面的加号。这会将一个或多个换行符的任何序列更改为单个
。
