file io - Reading a specific text in Java -

this kind of followup other question simple java regex read between two

now code looks this. reading contents of file, scanning whatever between src , -t1. running code return 1 correct link source file contains 10 , can't figure out loop. thought way might write second file on disk , remove first link original source can't code either:

file workfile = new file("page.txt"); bufferedreader br = new bufferedreader(new filereader(workfile)); string line;  while ((line = br.readline()) != null) {     //system.out.println(line);       string url = line.split("<img src=")[1].split("-t1")[0];         system.out.println(url);    }   br.close(); 

i think want like

import java.util.regex.*;  pattern urlpattern = pattern.compile("<img src=(.*?)-t1");  while ((line = br.readline()) != null) {         matcher m = urlpattern.matcher (line);         while (m.find()) {             system.out.println(m.group(1));         } } 

the regular expression looks strings beginning <img src= , ending -t1 (and looks shortest substrings possible, more 1 can found in line). part in parentheses "capture group" capture text gets matched; called group 1. then, each line, loop on find() find occurrences in each line. each time find one, print what's in group 1.
