importDataObject

I am trying to get importDataObject to import a text file and then parse the text stream to populate a drop down list.

(all code is being run in the console, I am using Adobe 9 Pro and LC2 Designer)
I am able to get the following to work perfectly
createDataObject("MyData.txt", "TXT\r\nDAT\r\nDOC\r\nDOCX");

But the following code (importing from a txt file) I have a problem with:
importDataObject("MyDataI.txt", "/c/temp/Test7.txt");
The txt file data file looks like this:
"TXT\r\nDAT\r\nDOC\r\nDOCX" // Same as the text stream using createDataObject
*******
Both file data get attached to the pdf checked with:
// list data objects
console.println("\nList of data objects:");
var d = dataObjects;
for (var i = 0; i < d.length; i++)
console.println("Data Object[" + i + "]=" + d[i].name);

List of data objects:
Data Object[0]=MyData.txt
Data Object[1]=MyDataI.txt
***********
When I list the contents I see both files but in different formats
using:
var oPropertyName = "MyDataI.txt"; // Change name to MyData.txt or MyDataI.txt
console.println("\nContents of data object: " + oPropertyName );
var oFile = getDataObjectContents(oPropertyName);
// convert to a string & print
var sContents = util.stringFromStream(oFile, "utf-8");
console.println("Length of contents: " + sContents.length);
console.println(sContents);

console.println("\nArray element contents " + oPropertyName);
var aContents = sContents.split("\r\n");
console.println("Number of arrays: " + aContents.length);
for (i = 0; i < aContents.length; i++)
console.println(i + ": " + aContents[i]);

Contents of data object: MyDataI.txt
Length of contents: 28
"TXT\r\nDAT\r\nDOC\r\nDOCX"

Array element contents MyDataI.txt
Number of arrays: 1
0: "TXT\r\nDAT\r\nDOC\r\nDOCX"

Contents of data object: MyData.txt
Length of contents: 19
TXT
DAT
DOC
DOCX

Array element contents MyData.txt
Number of arrays: 4
0: TXT
1: DAT
2: DOC
3: DOCX

Questions:
Why does the output data look different when reading the actual txt file?
When using LC2, and trying to import a text file, (to parse the text stream and pre load a drop down), is this the best function to use? I really do not want to use dynamic linking as do not want to deal with ODBC connect strings for this function.
What functions are available to LC2 designer for the importing of data as a text stream?
