Find&replace, RegEx, \10

[Gergely Apró]

I want to find&replace using regular expression.
If I put (something) in find and then \number to replace then the text in the bracket won’t be changed. I have 14 brackets in a single command. And when I write \10 to the replace, it return the first bracket and a zero, rather than the stuff in the 10th bracket.

If I correctly understood your question, just enclose it in brackets, as in \{10}.

Take care and have fun!

@astrosofista said in Find&replace, RegEx, \10:

\{10}

I don’t think that syntax works??

But this syntax ALWAYS works, in replace:

${1} <-- for group 1
${2} <-- for group 2
…
${N} <-- for group N

Thus for OP’s specific problem and example --> ${10} in replace field should work.

I neglected to mention the “group 0” match, which has the same syntax format as the ones I DID mention:

If you happen to need to refer to ALL of the matched text, you can use ${0} to refer to it.

Yes, my bad, ${10} is the thing.

@Gergely-Apró ,

The answers you have received are good.

If you would like more documentation on this, the official Notepad++ docs talk about the substitution expressions here .

Notepad++ uses what’s known as the “Boost engine” (currently v1.70) for handling the regular expressions, and that has its substitution documentation here
