Thanks to your scheme to follow after 3 attempts (but only because I did not understand some terms well) I was able to reassemble the localization file.
Now the menu is in Italian, even if some terms are translated (cupola instead Cappello :)) but in any case everything is finally working.
The only regret is that I have received a great deal of breath on this comunity
known through research and use of the program, But I will never be able to reciprocate the help received towards anyone, as I hardly know the first basic commands :(

Anyway, thank you very much again

sincere greetings

Tonio

Thanks again

OK ! So, let’s start with two INPUT files :

• The first file contains all the English translations :

<message name=" point could not be projected">
<message name=" polnt is out of tolerance">
<message name=" points are out of tolerance">
<message name=" points could not be projected">
<message name=" result is out of tolerance">
<message name=" results are out of tolerance">

• The second file contains all the Italian translations

il punto non poteva essere proiettato</message>
il punto è fuori tolleranza</message>
i punto sono fuori tolleranza</message>
non é stato possibile proiettare i punti</message>
il risultato è fuori tolleranza</message>
i risultato sono fuori tolleranza</message>

And you expect this OUTPUT file :

<message name=" point could not be projected">il punto non poteva essere proiettato</message>
<message name=" polnt is out of tolerance">il punto è fuori tolleranza</message>
<message name=" points are out of tolerance">i punto sono fuori tolleranza</message>
<message name=" points could not be projected">non é stato possibile proiettare i punti</message>
<message name=" result is out of tolerance">il risultato è fuori tolleranza</message>
<message name=" results are out of tolerance">i risultato sono fuori tolleranza</message>

In this case, we can simply use the native N++ Column mode, with the help of the BetterMultiSelection plugin, to achieve this goal !

However, if all your message name= lines are part of a larger XML file, you should, probably, follow the @peterjones advice and use a Python script

Now, I tested my method with two files of 10,000 records and everything went fine !

IMPORTANT : Of course, I suppose that your two INPUT files have, exactly, the same number of lines !

Follow carefully this road map :

• If the BetterMultiSelection plugin is not installed, in your N++ configuration :

  • Select the Plugins > Plugin Admin... option

  • In the first Available tab, select the BetterMultiSelection plugin

  • Click on the Install button

• Move to the beginning of the first line of your Italian translations file

• Select the Edit > Begin/End select N++ option

• Now, move to the end of the last line of your Italian translations file

• Hold down the Alt key and click on the mouse left button ( IMPORTANT )

• Select, again, the Edit > Begin/End select N++ option

Note : A partial column mode selection should occur

• Click simultaneously, on the Shift and the End keys

Note : The 10,000 lines are completely selected. This action may take some seconds !

• Copy all these lines in the clipboard ( Ctrl + C )

• Move to the end of the first line of the English translations file

• Add some space characters ( I would say a minimum of 20 )

• Paste the contents of the clipboard ( Ctrl + V )

Note : This action may be long enough, depending of your configuation ( ~ 45s with an old laptop )

• Now, open the Replace dialog ( Ctrl + H )

  • Untick all box options

  • SEARCH >\x20+

  • REPLACE >

  • Tick the Wrap around box option

  • Select the Regular expression search mode

  • Click on Replace All button

• Hit the Esc key to close the dialog

• Save your file ( Ctrl + S )

Here you are !

Thanks Peter for your input.
Unfortunately, as mentioned, I am not very familiar with codes and languages. I can hardly follow some tutorials and not always succeed.
However I try to attach a small screen, where I try to make people understand (in my ignorance) maybe better.
In summary from the original file, through the find and replace guides I was able to separate the texts, with the presumption of being able to put everything back together with the translated text.

I’m not 100% sure what you’re trying to ask.

But if you are trying to translate a lot of strings in a file, you might want to follow the advice in this recent discussion. To do so, you would need to have the PythonScript plugin, and then edit the translation table in the script, and then run it on your code. (See also the FAQ on how to use PythonScript solutions)

But if I have misunderstood your question, sorry. Maybe someone else will be able to reply in a way that’s meaningful to your question.
