Question

我愿用2条新行的“<代码><br>”; tag。 i. 想要的是

$string=~s/br>/

/s;

but somehow it doesn t work. Whereas it works fine for a single new line. i.e. if i do this:

$string=~s/br>/
/s;

罚款。我做了什么错误?

If you re talking about vim s substitute command then you probably want to use in the replacement string instead of . In this context vim treats as NULL, not newline.

<代码>相关氮:求助次替代/特殊:

<CR>    split line in two at this point
        (Type the <CR> as CTRL-V <Enter>)          *s<CR>*

      idem                                       *s/
*
<CR>   insert a carriage-return (CTRL-M)
        (Type the <CR> as CTRL-V <Enter>)          *s/<CR>*

      insert a <NL> (<NUL> in the file)
