如何在Java中将整个子字符串从“”(How to remove entire substring from '' in Java)

如何在Java中将整个子字符串从“<”移动到“>”(How to remove entire substring from '<' to '>' in Java)

我有一个输入字符串的程序。 我想删除字符'<'和'>'中的任何内容。 例如，如果字符串说

"P.S.<!-- BODY { color:white; background-color: transparent; font-family:sans-serif; } --> Hello how are you today?"

我希望输出字符串只包含"PS Hello how are you today?" 。 有没有简单的方法来在Java中做到这一点？ 谢谢

I have a program that takes an input string. I want to delete anything inside the characters '<' and '>'. For example if the string says

"P.S.<!-- BODY { color:white; background-color: transparent; font-family:sans-serif; } --> Hello how are you today?"

I want the output string to only contain "P.S. Hello how are you today?". Is there a simple way to do this in Java? Thanks

使用正则表达式：

newstr = str.replaceAll("<[^>]*>", "");

这意味着找到每个以<开始的子串，然后是任何数量的不是>的字符，然后是字符> 。 然后用空字符串""替换所有这些子字符串。

参考： java.lang.String.replaceAll（）

Use a regular expression:

newstr = str.replaceAll("<[^>]*>", "");

What this means is to find every substring beginning with <, then any number of characters that are not >, and then the character >. Then replace all these substrings with the empty string, "".
