在Java中的两个单词之间查找文本

Question

我希望在两个单词之间得到所有文本.例如:

String Testing="one i am here fine two one hope your are also fine two one ok see you two";

从上面的字符串中,我想获取数组中"one"和"two"之间的单词:

我的结果应该像这样存储在数组中:

String result[1] = i am here fine
String result[2] = hope your are also fine  
String result[3] = ok see you

在java中怎么办？

Answer 1

String input = "one i am here fine two one hope your are also fine two one ok see you two;";
Pattern p = Pattern.compile("(?<=\\bone\\b).*?(?=\\btwo\\b)");
Matcher m = p.matcher(input);
List<String> matches = new ArrayList<String>();
while (m.find()) {
  matches.add(m.group());
}

这将创建"一"和"两"之间所有文本的列表.

如果你想要一个不使用lookaheads/lookbehinds的简单版本,请尝试:

String input = "one i am here fine two one hope your are also fine two one ok see you two;";
Pattern p = Pattern.compile("(\\bone\\b)(.*?)(\\btwo\\b)");
Matcher m = p.matcher(input);
List<String> matches = new ArrayList<String>();
while (m.find()) {
  matches.add(m.group(2));
}

注意: Java数组从零开始而不是基于一个,因此在您的示例中,第一个结果将result[0]不是result[1].在我的解决方案中,第一场比赛是在matches.get(0).
