Question

I am new to java regex.Please help me. Consider the below paragraph,

Paragraph :

            Name abc
            sadghsagh
            hsajdjah N         


        

Answer 1

String s = "Name abc sadghsagh hsajdjah !!! Name ggg dfdfddfdf !!! Name hhhh sahdgashdg asjdhjasdh sadasldkalskd asdjhakjsdhja !!!!! ";
String startsWith = "Name";
String endsWith = "!!!";

// non-greedily get all groups starting with Name and ending with !!!
String pattern = String.format("(%s).*?(%s)", Pattern.quote(startsWith), Pattern.quote(endsWith));
System.out.println(pattern);

Matcher m = Pattern.compile(pattern, Pattern.DOTALL).matcher(s);
while (m.find()) 
  System.out.println(m.group());

output:

(\QName\E).*?(\Q!!!\E)
Name abc sadghsagh hsajdjah !!!
Name ggg dfdfddfdf !!!
Name hhhh sahdgashdg asjdhjasdh sadasldkalskd asdjhakjsdhja !!!
