If you have file names of the fashion alpha characters followed by
underscore followed by numerals, dot and alpha characters, the following
code will provide you the number part of file name:

 \makeatletter
 \def\parseFile#1{\@parseFile#1\@nil}
 \def\@parseFile#1_#2.#3\@nil{#2}
 \makeatother

\parseFile{D:/vinoth/obes/jbi_1221.tex}  ==> 1221
