Yap the row and column will change but i had already parse these lines into my code. However, i am still figuring on how to get the integer number 1,2,2,4 of the text file using while loop and not include the "</matrix>" in the reading. Can this be done?If the numbers you want are at fixed byte positions in the file that are known ahead of time, you can use java.io.RandomAccessFile to skip to those positions. However, that seems unlikely.
If, as is the more likely case, those are not at fixed positions, you'll have to read everything preceding them. (Note that this is not a Java issue. This is how file I/O works.) You'll need to ignore the lines that are meaningless to you (read those lines and do nothing with them) figure out, by whatever rules you have--line numbers, preceding tokens, whatever--when you're at the lines you do care about, and then read and process those lines accordingly.
