JavaScript正则表达式：正确识别段落句子端点的方案求助

我在Stack Overflow上查阅了诸多解决方案，经测试后发现它们都难以完成段落句子端点识别的任务。当前使用的正则表达式/(?<![A-Z]\.)(?<=[.!?;])(?=[ A-Z])/已接近需求，但遇到Mr.、Mrs.这类缩写时会失效。希望实现两种效果：要么提取所有句子，要么按带标点的句子结尾进行分割。

优化后的正则方案 #

针对缩写导致的分割错误，我们在原正则基础上添加负向预查排除常见头衔缩写，避免在Mr.、Mrs.这类词后误分割句子：

/(?<!(Mr|Mrs|Ms|Dr|Sr|Jr)\.)(?<=[.!?;])(?=[ A-Z])/g

正则逻辑说明 #

• (?<!(Mr|Mrs|Ms|Dr|Sr|Jr)\.)：负向预查，排除前面是指定缩写加句号的情况，过滤头衔缩写的干扰
• (?<=[.!?;])：匹配句子结尾的标点符号（句号、感叹号、问号、分号）
• (?=[ A-Z])：匹配标点后紧跟空格和大写字母的位置，符合英文句子大写开头的规则

如果需要支持更多缩写，只需在括号内补充对应的缩写即可，例如(?<!(Mr|Mrs|Ms|Dr|Sr|Jr|Prof|Capt)\.)。

两种实现方式 #

1. 按句子结尾分割字符串 #

以JavaScript为例，使用split()方法完成分割：

const testStr = '上述测试字符串内容';
const regex = /(?<!(Mr|Mrs|Ms|Dr|Sr|Jr)\.)(?<=[.!?;])(?=[ A-Z])/g;
const splitResult = testStr.split(regex);
console.log(splitResult);

2. 提取所有完整句子 #

通过匹配直接提取包含结尾标点的完整句子：

const testStr = '上述测试字符串内容';
const extractRegex = /(.*?(?<!(Mr|Mrs|Ms|Dr|Sr|Jr)\.)[.!?;](?=[ A-Z]|$))/g;
const extractedSentences = testStr.match(extractRegex);
console.log(extractedSentences);
