Extract string between two strings in java

Question

I try to get string between <%= and %>, here is my implementation:

String str = \"ZZZZL <%= dsn %> AFFF <%= AFG %>\";
Pattern pattern = Patter         


        

Answer 1

Your pattern is fine. But you shouldn't be split()ting it away, you should find() it. Following code gives the output you are looking for:

String str = "ZZZZL <%= dsn %> AFFF <%= AFG %>";
Pattern pattern = Pattern.compile("<%=(.*?)%>", Pattern.DOTALL);
Matcher matcher = pattern.matcher(str);
while (matcher.find()) {
    System.out.println(matcher.group(1));
}
