[jdom-interest] Cleaning up EOS marker

[Paul Philion]

Tim -

Here's my "CleanUpInputStream". Nothing fancy, but it works for me. I
recommend wrapping a BufferedInputStream around the input before this...

InputStream in = new CleanUpInputStream(new BufferedInputStream(new
FileInputStream("fileName")));

----

public class CleanUpInputStream extends FilterInputStream {
 public CleanUpInputStream(InputStream in) {
  super(in);
 }

 public int read() throws IOException {
  int ch = in.read();
  if (ch == 10 || ch == 13 || ch == 9 || ch == -1) {
   return ch;
  }
  else if (ch < 32 || ch > 126) {
   return ' ';
  }
  return ch;
 }

 public int read(byte[] data, int offset, int length) throws IOException {
  int result = in.read(data, offset, length);
  for (int i = offset; i < offset + length; i++) {
   int ch = data[i];
   if (ch == 10 || ch == 13 || ch == 9 || ch == -1) {
    // nothing
   }
   else if (ch < 32 || ch > 126) {
    data[i] = (byte)' ';
   }
  }
  return result;
 }
}
