What kind of regex should I use for the following template?

Question

I'm writing a Java program that calculates a person's average salary, and prints the monthly deductions in a template. The template is something like this:

==============BILL==============
|  NAME: xXxX     BRANCH : xxx |
|                              |
|    Month 1 : xxx.xxx         |
|    Month 2 : xxxx.xx         |
|     <other Months>           |
|    Month 12 : xxx.xx         |
|                              |
|     TOTAL : ____________     |
================================

I am using the following pattern to try and capture the elements:

//template is stored in string.
String[] lines = msg.split("\n");
Pattern p = Pattern.compile("[xX\\._]+");
for(String line : lines){
    Matcher m = p.matcher(line);
    if(m.find()){
        System.out.println(m.group());
    }
    else{
        System.out.println("no match found...");
    }
}

The output I'm getting is something like this:

xXxX
xxx.xxx
xxxx.xx
xxx.xx
____________

However, I'm not able to match the 'xxx' of BRANCH. How do I extract that pattern?

Answer 1

Change

if(m.find()){
    System.out.println(m.group());
}

to

while(m.find()){
        System.out.println(m.group());
}

as NAME and BRANCH are on the same line.

Matcher#find() will find first match in string, not all matches. To get all matches you have to call find() multiple times.
