Replace help

Y M

Hello, I would like to replace multiple words… In a file I have a lot of colordiffuse=“[hexcolor]” with differents colors so colordiffuse=“FF545287” ; colordiffuse=“00FFFFFF” ,etc… And what I would like to to replace all of these lines by colordiffuse=“FF000000” so by a single color

Is it possible ?

It looks like the colors are hexadecimal values and each are 8 digits. If this is the case, then you can use
find what:(?<=colordiffuse=")[[:xdigit:]]{8}(?!>")
replace with:FF000000
and check regular expression checkbox

Thanks !

@Ekopalypse said in Replace help:

find what:(?<=colordiffuse=")[[:xdigit:]]{8}(?!>")

That works for the sample data, and the OP seems happy.

But I’m curious: Why did you choose a negative lookahead (?!>") saying that the next two characters (after the 8 hex digits) aren’t >", rather than using a positive lookahead (?=") saying that the next character (after the 8 hex digits) must be "? If >" had been mentioned as an exception, I would understand using that, but as it is, that seems an interesting choice, and I wanted to see if there was any insight behind it, or just arbitrary on your part?

And how to do that when it is colordiffuse=“[something]”, not only hexadecimal values but everything in the “”

Nothing special, just a pure typo.
I actually wanted to type the positive lookahead but for whatever reason … :-(
