Please help me to replace text like the following condition

[Nguyen Wanderoz]

I have a text file like the folowing one:
I want to replace text according to those conditions:

if in the [FEN] string, there is a w, (case sensitive) then replace the uper [Result"*“] to [Result"1-0”]

if in the [FEN] string, there is a b (case-sensitive) then replace the uper [Result"**“] to [Result"0-1”]

Please help me, is there any way to this in notepad++
Thank you.

Hello @nguyen-wanderoz and All,

No problem with a search using regular expressions ! And, as you precisely explain you needs, it was very easy to built the right S/R :-)) So :

• Open the Replace dialog ( Ctrl + H )

• Select the Regular expression search mode

• Tick the Wrap option option

SEARCH : (?s-i)(?<=[Result\x20")\*(?=.*?[FEN\x20.*?\x20((w)|b)(\x20-){2})

REPLACE (?{2}1-0:0-1)

• Click on the Replace All button, exclusively ( The step by step replacement, with the Replace button, does NOT work, because of the look-behind structure ! )

Et voilà !

---

Notes :

• First, note that the [ symbol, ( as well as some others *, +, ?, |, … …) is a special regex character and, thus, must be escaped, with the \ symbol, to be taken literally

• Note, also, that the \x20 syntax stands for a single space character. Of course, you may hit the space key, instead of writing \x20, in the Search what: zone

• As usual, at beginning, the modifiers (?s-i) means that :

  • The dot ( . ) will match any single character, Standard or EOL one ( s )

  • The search is performed in a sensitive way ( -i )

• This regex, essentially, look for the star character ( \* ), of the zone [Result "*"], but ONLY IF two conditions are TRUE :

  • It must be preceded, of course, with the string [Result\x20", due to the fix-length look-behind (?<=[Result\x20")

  • It must be followed , due to look-ahead structure (?=.*?[FEN\x20.*?\x20((w)|b)(\x20-){2}), by :

    • The shortest range of any character till the string [FEN\x20

    • Then, followed, again, with the shortest range of any character till the string \x20((w)|b)(\x20-){2}

• Before the \x20-\x20- string, it searches for the lower-case letter w or b ( group 1 ) and note that when case w happens, it is stored as group 2 for later use in replacement

• Now, due to the conditional replacement (?{2}1-0:0-1), the search match ( the * char ) is, then, changed into :

  • The string 1-0 if group 2 exists ( case w )

  • The string 0-1 if group 2 does not exist ( case b )

Replace All

Hello @guy038 ,

Thank you very much! It worked like magic!!! And your crystal cleared explaination make a dummy like me can get to understand. Surely, I need to start to learn about regular expressions.
