java - java 两个特定单词之间的文本

Question

如何在“谢谢”和“此致”之间添加字符串文本

String emailtext= "Dear (RECIPIENT_PREFIX) (RECIPIENT_FIRST_NAME) (RECIPIENT_LAST_NAME), 
Thank you for being a part.....................more text ......

Thank you for your time. Filling out these sections with ...more     text....      for which you are chosen.

Sincerely,

xyz
adresss"

我尝试过:

String pattern = "(Thank)((.|\n)*)(?=Sincerely,)";

Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(emailtext);

if (m.find( )) {
    System.out.println("Found value:" + m.group(0));
    System.out.println("Found value:" + m.group(1));
    System.out.println("Found value:" + m.group(2));
} else {
    System.out.println("NO MATCH");
}

错误显示:

java.lang.StackOverflowError at java.util.regex.Pattern$CharProperty.match(Pattern.java:3692) at java.util.regex.Pattern$Branch.match(Pattern.java:4502) at java.util.regex.Pattern$GroupHead.match(Pattern.java:4556) at java.util.regex.Pattern$Loop.match(Pattern.java:4683) at java.util.regex.Pattern$GroupTail.match(Pattern.java:4615) at java.util.regex.Pattern$BranchConn.match(Pattern.java:4466) at java.util.regex.Pattern$CharProperty.match(Pattern.java:3694) at java.util.regex.Pattern$Branch.match(Pattern.java:4502) at java.util.regex.Pattern$GroupHead.match(Pattern.java:4556) at java.util.regex.Pattern$Loop.match(Pattern.java:4683)

正确的 ans 应显示:

"Thank you for being a part.....................more text ......

Thank you for your time. Filling out these sections with ...more text.... for which you are chosen."
