String Newline not displaying in Doors - ibm-doors

Question

I have csv file containing some data like:
374,Test Comment multiplelines \n Here's the 2nd line,Other_Data
Where 374 is the object ID from doors, then some commentary and then some other data.
I have a piece of code that reads the data from the CSV file, stores it in the appropriate variables and then writes it to the doors Object.
Module Openend_module = edit("path_to_mod", true,true,true)
Object o ;
Column c;
string attrib;
string oneLine ;
string OBJECT_ID = "";
string Comment = "";
String Other_data = "";
int offset;
string split_text(string s)
{
if (findPlainText(s, sub, offset, len, false))
{
return s[0 : offset -1]
}
else
{
return ""
}
}
Stream input = read("Path_to_Input.txt");
input >> oneLine
OBJECT_ID = split_text(oneLine)
oneLine = oneLine[offset+1:]
Comment = split_text(oneLine)
Other_data = oneLine[offset+1:]
When using print Comment the output in the DXL console is : Test Comment multiplelines \n Here's the 2nd line
for o in Opened_Module do
{
if (o."Absolute Number"""==OBJECT_ID ){
attrib = "Result_Comment " 2
o.attrib = Comment
}
}
But after writing to the doors object, the \n is not taken into consideration and the result is as follows:
I've tried putting the string inside a Buffer and using stringOf() but the escape character just disappeared.
I've also tried adding \r\n and \\n to the input csv text but still no luck

Answer 1

This isn't the most efficient way of handling this, but I have a relatively straightforward fix.
I would suggest adding the following:
Module Openend_module = edit("path_to_mod", true,true,true)
Object o ;
Column c;
string attrib;
string oneLine ;
string OBJECT_ID = "";
string Comment = "";
String Other_data = "";
int offset;
string split_text(string s)
{
if (findPlainText(s, sub, offset, len, false))
{
return s[0 : offset -1]
}
else
{
return ""
}
}
Stream input = read("Path_to_Input.txt");
input >> oneLine
OBJECT_ID = split_text(oneLine)
oneLine = oneLine[offset+1:]
Comment = split_text(oneLine)
Other_data = oneLine[offset+1:]
//Modification to comment string
int x
int y
while ( findPlainText ( Comment , "\\n" , x , y , false ) ) {
Comment = ( Comment [ 0 : x - 1 ] ) "\n" ( Comment [ x + 2 : ] )
}
This will run the comment string through a parser, replacing string "\n" with the char '\n'. Be aware- this will ignore any trailing spaces at the end of a line.
Let me know if that helps.
