替换 Java 中的子字符串

Question

What is a proper way to replace a part of string, matching some criteria, for example, if I have this text:

"some_text1((some_text2) and 1)some_text3"

I want to convert it into:

"some_text1(some_text2)some_text3"

In this example, the criteria is: if there is ( ... and 1) , I want to replace it with ... (some text, I don't know what is it).

Edit: According to answers I've written this function:

static String replaceRecursive(String str, String pattern, String matcher) {
    String res = str.replaceAll(pattern, matcher);
    if (res == str) {
        return res;
    }
    return replaceRecursive(res, pattern, matcher);
}

usage:

String str = "((((X and 1) and Y) and 1) or Z)";

System.out.println(replaceRecursive(str, "\\((.*) and 1\\)", "$1"));

It seems to be working

Update: It still doesn't work. There is problem in brackets. For example, if str = "((some_text1)((some_text2) and 1))" , the first opening bracket will be removed, instead of the third one.

Answer 1

How about something like this:

String s = "some_text1((some_text2) and 1)some_text3";
System.out.println(s.replaceAll("\\(.*?(\\(.*?\\)).*?\\)", "$1"));

This matches nested parenthesis and puts the inner parenthesis in match group 1, which is then used in the replacement string, effectively discarding the outer parenthesis (and its contents).

Needless to say, if either some_text1 or some_text3 contains parenthesis, things will go wrong.
