Saving/reading large xml string to/from file

[staiple]

So, my app receives a large xml from a soap server. I wish to save this in a file, for later use. I managed to do this, and to read the file. BUT the result (after reading) is a garbled xml! A large portion of text (412 characters) from the latter part of the xml is copied and pasted at the end of my xml, and I can't figure out why this is happening. I have tried 2 ways to write the file and 2 ways to read the file, no dice! (will post code below) Note: xml is large 5000-20000 characters, so I used methods to keep eclipse from returning out of memory error.BOTTOM LINE:-input xml file is correct-output xml file is incorrect-tried 2 save methods-tried 2 read methods-wtf?!save code 1:\[code\] InputStream is = new ByteArrayInputStream(string.getBytes()); FileOutputStream fos = ctx.openFileOutput(filename, Context.MODE_PRIVATE); byte[] buffer = new byte[1024]; int length; while ((length = is.read(buffer))>0){ fos.write(buffer, 0, length); } fos.flush(); fos.close(); is.close();\[/code\]save code 2 :\[code\] InputStream is = new ByteArrayInputStream(string.getBytes()); BufferedReader reader = new BufferedReader(new InputStreamReader( is, "iso-8859-1"), 8); FileOutputStream fos = ctx.openFileOutput(filename, Context.MODE_PRIVATE); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { Log.e("stuff is good", "line: "+line); sb.append(line); if (sb.toString().length() > 10000) { fos.write(sb.toString().getBytes()); fos.flush(); sb = new StringBuilder(); } } fos.write(sb.toString().getBytes()); fos.flush(); is.close(); fos.close();\[/code\]read code 1:\[code\] FileInputStream fis = openFileInput("caca"); int c; StringBuilder fileContent = new StringBuilder(); while((c=fis.read())!=-1) { fileContent.append((char)c); } fis.close(); Log.e("TEST TEST", "XML length = " +String.valueOf(fileContent.length()) ); Log.e("TEST TEST", "XML = " +fileContent );\[/code\]read code 2 :\[code\] FileInputStream fis; fis = openFileInput("caca"); StringBuffer fileContent = new StringBuffer(""); byte[] buffer = new byte[1024]; int i =1; while (fis.read(buffer) != -1) { fileContent.append(new String(buffer)); Log.v("TEST"+ String.valueOf(i), new String(buffer) ); i++; } Log.e("TEST TEST", "XML length = " +String.valueOf(fileContent.length()) ); Log.e("TEST TEST", "XML = " +fileContent );\[/code\]save to file code :\[code\] File myFile = new File("/sdcard/mysdfile.txt"); myFile.createNewFile(); FileOutputStream fOut = new FileOutputStream(myFile); OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut); myOutWriter.append(fileContent); myOutWriter.close(); fOut.close(); Toast.makeText(getBaseContext(), "Done writing SD 'mysdfile.txt'", Toast.LENGTH_SHORT).show();\[/code\]Sorry for the long post, but after 3 days, I'm at my wits end. Any input would be nice, thank you!
