finding a substring

Hello all, I need to read lines within a text file that might have a " value='somevalue' " string the position of "value=" varies from line to line but there's only one "value=" in each line. So what I need to do is to parse the file and find the "value=" and put their values in an array. Suposse I have the following text file with 3 lines : snLADEFEFfdgvalue="1234"rwgjngrgj value="23456"gkerlgwg 132fngdhbvalue="5678"bfl928 I would like to get an array like this: array[0] = 1234; array[1] = 23456; array[2] = 5678; The value is delimited always by double quotes but its position on the line varies. I need to extract these values and put them on a string. Any ideas or help is appreciated. Thanks in advance.
