regex remove everything between 2 strings
提问by Decrypter
I need a regex for my replaceAll that removes everything between 2 strings and the strings themselves.
我的 replaceAll 需要一个正则表达式来删除 2 个字符串和字符串本身之间的所有内容。
For example if I had something like.
例如，如果我有类似的东西。
stackoverflow is really awesome/nremove123/n I love it
I was trying to do a replaceAll like this line.replaceAll("/n*/n", ""); This should result in
我试图像这样 line.replaceAll("/n*/n", ""); 这应该导致
stackoverflow is really awesome I love it
I thought the asterisk meant anything but can't get it to work?
我认为星号意味着什么，但不能让它工作？
cheers
干杯

No, the .means any character. *means any number of the previous things. So anything is .*.
What you need is
不，这.意味着任何字符。*指任何数量的先前事物。所以任何事情都是.*。你需要的是
/n.*/n
If you want to leave an empty space between words use this instead
如果你想在单词之间留一个空格，请改用这个
replaceAll("/n.*/n *", " ")

I think you need a dot:
我认为你需要一个点：
replaceAll("/n.*/n")
replaceAll("/n.*/n")
回答by Sorter
This will remove anything between ab.
这将删除ab.
replaceAll("ab([;\s\w\"\=\,\:\./\~\{\}\?\!\-\%\&\#$\^\(\)]*?)ab","");
Please add any special character, if I'm missing it.
请添加任何特殊字符，如果我遗漏了它。
