Thread: open text file and edit any line start with name

Why is createNewFile being called inside of the loop? Why is it trying to create the input file?
What is in oq.txt when the program finishes?

What is shown on the console when the program is executed?

Please copy what is printed on the console and paste it here.

Why is createNewFile being called inside of the loop?

Is there other code that reads/writes the output file? I don't see any statements that would remove the space.
The code does not remove a space for me.

run:
File already exists.
File already exists.
File already exists.
File already exists.
File already exists.

<AzanID="1">
<AzanID="2">

must be

<Azan ID="1">
<Azan ID="2">

like original file

Why is createNewFile being called inside of the loop? where i must write that?

--- Update ---

in the oq.txt file is:

<Azan ID="1">
<Day>Sunday</Day>
<date>1400/01/01</date>
<morning>04:43:02
<Sunrise>06:06:49
<Noon>12:12:09
<sunset>18:17:30
<evening>18:35:33
<midnight>23:30:16
</Azan>
 
<Azan ID="2">
<Day>Monday</Day>
<date>1400/01/02</date>
<morning>05:41:30
<Sunrise>07:05:23
<Noon>13:11:51
<sunset>19:18:20
<evening>19:36:23
<midnight>00:29:55
</Azan>

in new file

<AzanID="1">
<Day>Sunday</Day>
<date>1400/01/01</date>
<morning>04:43:02</morning>
<Sunrise>06:06:49</Sunrise>
<Noon>12:12:09</Noon>
<sunset>18:17:30</sunset>
<evening>18:35:33</evening>
<midnight>23:30:16</midnight>
</Azan>
 
<AzanID="2">
<Day>Monday</Day>
<date>1400/01/02</date>
<morning>05:41:30</morning>
<Sunrise>07:05:23</Sunrise>
<Noon>13:11:51</Noon>
<sunset>19:18:20</sunset>
<evening>19:36:23</evening>
<midnight>00:29:55</midnight>
</Azan>

--- Update ---

i think

myStr.startsWith

Cannot recognize space. because when before or after a word is placed space, it does not read space

I copied the contents of the oq.txt file that was posted and saved it on my PC.
When I run the posted code I get this in the testFile1.txt:

<Azan ID="1">
<Day>Sunday</Day>
<morning>04:43:02</morning>
<Sunrise>06:06:49</Sunrise>
<Noon>12:12:09</Noon>
<sunset>18:17:30</sunset>
<evening>18:35:33</evening>
<midnight>23:30:16</midnight>
</Azan>
<Azan ID="2">
<Day>Monday</Day>
<morning>05:41:30</morning>
<Sunrise>07:05:23</Sunrise>
<Noon>13:11:51</Noon>
<sunset>19:18:20</sunset>
<evening>19:36:23</evening>
<midnight>00:29:55</midnight>
</Azan>

There is a space before the ID=
Also Notice there is NOT a blank line between </Azan> and <Azan ID="2">
Also this line is NOT in the new file: <date>1400/01/01</date>
I do not understand how what you say is in new file came from the posted code.

There must be a different program being used to create the new file.

Is your problem solved now?
