如何替换引号之间出现的任何单词 [英] How to replace any occurrence of a word between quotes

问题描述

我需要能够在单引号之间替换所有出现的单词and。例如，在字符串中用XXX替换和：

I need to be able to replace all occurrences of the word "and" ONLY when it occurs between single quotes. For example replacing "and" with "XXX" in the string:

这和那个'和你我和别人'而不是'她和他'

结果：

这那个'和你XXX我XXX他人'而不是'她XXX他'

我能够提出正则表达式几乎得到了所有案例，但我在两组引用文本之间没有和。

I have been able to come up with regular expressions which nearly gets every case, but I'm failing with the "and" between the two sets of quoted text.

我的代码：

String str = "This and that 'with you and me and others' and not 'her and him'";

String patternStr = ".*?\\'.*?(?i:and).*?\\'.*";
Pattern pattern= Pattern.compile(patternStr);
Matcher matcher = pattern.matcher(str);
System.out.println(matcher.matches());
while(matcher.matches()) {
    System.out.println("in matcher");
    str = str.replaceAll("(?:\\')(.*?)(?i:and)(.*?)(?:\\')", "'$1XXX$2'");
    matcher = pattern.matcher(str);
}

System.out.println(str);

推荐答案

试用此代码：

str = "This and that 'with you and me and others' and not 'her and him'";
Matcher matcher = Pattern.compile("('[^']*?')").matcher(str);
StringBuffer sb = new StringBuffer();
while (matcher.find()) {
   matcher.appendReplacement(sb, matcher.group(1).replaceAll("and", "XXX"));
}
matcher.appendTail(sb);
System.out.println("Output: " + sb);

OUTPUT

OUTPUT

Output: This and that 'with you XXX me XXX others' and not 'her XXX him'
