The number of deliveries is unknown, but if I found ALLOW or REJECT or MERGE or AGGREGATE that's mean there are no more deliveries. My idea was to extract each DELIVERY source code apart(which is the substring existing between two Delivery or substring existing between delivery and one of these words (ALLOW,REJECT,MERGE,AGGREGATE)) so tried this Pattern:

Pattern p = Pattern.compile("DELIVERY\\s.*?[\\nDELIVERY|\\nALLOW|\\nREJECT|\\nMERGE|\\nAGGREGATE]?",Pattern.DOTALL);

but it doens't works for me.

以下代码应该适合您：

Pattern p = Pattern.compile("(?s)(\\bDELIVERY\\b.+?(?=\\b(?:DELIVERY|ALLOW|REJECT|MERGE|AGGREGATE)\\b))");
Matcher m = p.matcher(str); // str is your input string
boolean found = false;
while (m.find()) {
    System.out.printf("Deliver: %s%n", m.group(1));
    found = true;
}

if (!found) {
    System.out.println("Didn't Match");
}
