replace empty function from the old format to the new format

I have about 300 files which has the function getDBBackend().
How to write a program to change the empty function from the old format to the new format?

Old empty function format are either:
function getDBBackend()
{
// Not available
} // getDBBackend

or:
function getDBBackend()
{

} // getDBBackend

New empty function format is:
function getDBBackend()
{
// DB backend not applicable, use test backend
getTestObject();
} // getDBBackend

If the function is not empty, then it will not be changed:
function getDBBackend() {
$msg = db_start_dget(MIO_DGET_DATA);
//...
}

I think it's easiest in python

Code:

oldform1 = "function getDBBackend()\n{\n ..."
oldform2 = """function getDBBackend()
{

} // getDBBackend"""
filenames = ["file1", "file2", ]
for fname in filenames:
 data = file(fname).read()
 data = data.replace(oldform1, newform)
 data = data.replace(oldform2, newform)
 file(fname, "w").write(data)

with appropriate values of filenames, oldform{1,2} and newform.

to lowpro2k3:
sed struck me first too--but I can't seem to be able to do it in a fairly simple way (i.e. without stuffing lines into the holding space and doing nasty things with them there).

So if you have a script of about, say, 1-5 lines, please post it

Agreed, I know it can be done but I'm far from slick enough to write a pretty one liner. It would be a mess of temp files that would work for me - ugly, but gets the job done
