RegEx help for NotePad++

I need help with RegEx I just can't figure it out I need to search for broken Hashtags which have an space.

So the strings are for Example:

#ThisIsaHashtagWith Space

But there could also be the Words "With Space" which I don't want to replace.

So important is that the String starts with "#" then any character and then the words "With Space" which I want to replace to "WithSpace" to repair the Hashtags.

I have a Document with 10k of this broken Hashtags and I'm kind of trying the whole day without success.

I have tried on regex101.com

with following RegEx: ^#+(?:.*?)+(With Space)

Even I think it works on regex101.com it doesn't in Notepad++

Any help is appreciated.

Thanks a lot. BR

Try this? (#.*)( ).

I tried this in Notepad++ and you should be able to just replace all with $1. Make sure you set the find mode to regular expressions first.

const str = "#ThisIsAHashtagWith Space";

console.log(str.replace(/(#.*)( )/g, "$1"));

In your current regex you match a # and then any character and in a capturing group match (With Space).

You could change the capturing group to capture the first part of the match.

(#+.*?)With Space

Then you could use that group in the replacement:

$1WithSpace

As an alternative you could first match a single # followed by zero or more times any character non greedy .*? and then use \K to reset the starting point of the reported match.

Then match With Space.

#+(?:.*?)\KWith Space

In the replacement use WithSpace

If you want to match one or more times # you could use a quantifier +. If the match should start at the beginning of string you could use an anchor ^ at the start of the regex.

Try using ^(#.+?)(With\s+Space) for your regex as it also matches multiple spaces and tab characters - if you have multiple rows that you want to affect do gmi for the flags. I just tried it with the following two strings, each on a separate line in Notepad++

#blablaWith Space
#hello#@#$aWith    Space

The replace with value is set to $1WithSpace and I've tried both replaceAll and replace one by one - seems to result in the following.

#blablaWithSpace
#hello#@#$aWithSpace

Feel free to comment with other strings you want replaced. Also be sure that you have selected the Regular Extension search mode in NPP.
