The answer to this partly depends on what kind of cells the code is
contained in.  Your solution assumes that the cells in question are ,
for example, Text cells or Program cells.  And in this case the Cell's
cell expression has a string as its first argument as long as there is
no formatting in the cell.  I wouldn't consider your solution a hack--
it is a sensible starting point for doing what you want to do.
Mathematica has all sorts of notebook manipulation functions that are
specifically in place for this sort of thing.  And "A WorkLife
FrameWork " is built out of thousands of instances of this sort of

Here is another example of how to do it

nb= the notebook object of your notebook


  NotebookFind[nb, "Java", All, CellTags];

 nbr = NotebookRead[nb];

 nbr /. Cell[x_, ___] :> x

Hope that this helps...
