Have you considered using ant(see the replace task) or sed or something to 
do this?

IF you you antlr possibly you could just lex it provided you knew the 
version string you were looking for was unique enough  Otherwise you will 
need to parse it and then search through the resulting AST, do the replace 
then print the AST  out again....remembering to preserve whitespace etc
