Trying to make a script that inserts/replace text at specifick lines in ex. ini files..

Can't get it to work..
How should the script look like?
is it possible to specify more where to insert/replace text?
line 2
number 15
DOREPLACE or DOINSERT

???


EXAMPLE:


E:\test.ini
--------------
[jalla]
1=box
2=mxm



menu.xml
-----------------------
callfile %abspath%\scripts\textedit.asx E:\test.ini line2 1=xob



something like that :?
