(newbie) definitive class/regex for stripping empty lines from text files?

[christek]

Hello all,
This would seem to be a common task but I can't seem to find an answer
on the web.
Is there a definitive/well tested class/library that can strip blank
lines and lines with nothing but spaces from a text file using
FileInputStream?
Regards,
Chris

How difficult can it be to add a one-line conditional to the standard
idiom...

BufferedReader br = new BufferedReader(...);
String line;

while ((line = br.readLine()) != null) {
if (line.trim().length() != 0) {
// whatever
}
}

br.close();

Note too that you should be using a Reader to handle text files, not
an InputStream.
