the second run has to be a loop through the first array's contents:
+ (NSArray*) convertString:(NSString*) theString;
{
NSArray *anArray = [theString componentsSeparatedByString:@"\r"];
NSMutableArray *aMasterArray = [NSMutableArray array];
for(i=0; i<[anArray count]; i++)
{
NSString *aString = [anArray objectAtIndex:i];
[aMasterArray addObject:[aString componentsSeparatedByString:@"\t"]];
}
return aMasterArray;
}

you question went to the cocoa-list.
so no C++ answer here, only Objective-C.
try NSStrings - (NSArray *)componentsSeparatedByString:(NSString
*)separator
that breaks your string into parts and delivers an array. then run
that array, to separate the contained strings again.
the first run works very well with this code:
@implementation string2list
+ (NSArray*) konvertString:(NSString*) theString;
{
return [theString componentsSeparatedByString:@"\r"];
}
@end
but the second run gets an error.
what is wrong. how can i get a list of lists?

hi,
i need to make a list of lists from a tab and return delimited string
like : "data1 [tab] data2 [tab] data3 [return] data4 [tab] data5
[tab]
data6"
[tab] and [return] are the delimiters!!
this string should become a list like: {{"data1", "data2",
"data3"},{"data4", "data5", "data6"}}
i have an applescrip:
set x to (mysql's ExecuteMySQLCommand(sqlCommand))
set addressData to {}
set AppleScript's text item delimiters to return
repeat with i from 1 to count text items of x
if i - 1 then
set y to text item i of x
set AppleScript's text item delimiters to tab
set _name to text item 1 of y & " " & text item 2 of y
set end of addressData to {_name, text item 3 of y, text item 4 of
y, text item 5 of y}
set AppleScript's text item delimiters to return
end if
end repeat
but this is to slow.
i.e. the script needs for 188 text items of x about a minute on a
eMac
1Ghz!
i guess a c++ routine will be much faster bu i don't have any
experiences with c++ so anybody can help me?
