Dears,
I have one text file contains many lines, I’m searching for a word inside it, and whenver found I will delete all lines before and after that line, How to achieve this ?
Thanks in advance
Hi @hsendel
First read the text file and store in string varible
Then split the string based on new line as
Stringvariable.Split(Environment.NewLine.TocharArray) will split the lines based on new line and store in array
After that use for each loop and loop through line
Inside that use the if activitiy with condition line.contains(word)
If line contains that word , in then section
Assign that line to a string variable ‘Line’ and also array index to integer variable ‘index’ and then use break activitiy to exit out of loop
create integer variable step , intalise it with zero
Create another string variable a , assign it with “”
After that create another while loop with condition step <=index
inside the while loop , put if condition with condition as step <index:
if this condition satisfies in then section ,
Assign a = a+ Environment.NewLine
Assign step = step+1
In else condition put like this
Assign a = a+ Line
Out of loop use write text activitiy to.write the string ‘a’ to same notepad file in the same position earlier it was
Hope you got the logic
Mark it as solution if you got it

No need to delete ALL lines before and after. That’s the same as taking ONLY that line. Follow the beginning steps @NIVED_NAMBIAR mentioned: Split string on new line, for each str in ArrStr if str.toupper.contains(“MYWORD”) Then assign MyLine = str, break activity.
Now you have a string variable called MyLine that contains only the nth Line containing MyWord

Thanks a lot @NIVED_NAMBIAR , Possile to generate an example for the same?
I have started the process and fail to continue due to some points that still not clear for me.Main.xaml (9.8 KB) Thanks in advance
Thanks @ Dave, but what if we have the word repeated many times ? the aim of doing this is to keep only the 1st line where the word occurs for the 1st time and following procedure shared by @NIVED_NAMBIAR this can be achieved I guess, still only some steps not clear for me.
Because of the break activity, it will stop after it finds the first line containing the word

Hello @NIVED_NAMBIAR, Seems there is a missing package as per the bellow error msg :
That is split string activitiy provided by workflow manager package , I had disabled it
U can use this to split the string
Already I had used the string manipulation to split the string
So delete that split string activitiy. I add that activitiy for testing ,
I will share the updated workflow now

Strange!!! I see you’re using newer version of Studio, Can this be an issue?
