Hello Community,
I need help in creating this regex for replacing the text

Heres the sample input:

<variable class="loves">[loves] My dog loves dog food </variable>

Heres the sample output i am expecting:

<variable class="loves">[loves] My dog hates dog food </variable>

The regex i am currently using highlights the word loves written in square brackets as well as outside the square bracket. I want to ignore the word loves written in square bracket

Thank you

It works, But i wont be knowing the previous and next text. So other times it wont work Its dog in this case now. Also need to make sure i am editing texts with variable texts only
Lets try with some other examples
Input:

<variable class="loves">[loves] My dog loves dog food </variable>
<variable class="loves">[loves] My *cat* loves **dog** food </variable>
<li class="loves">[loves] My dog loves dog food </li>

Output

<variable class="loves">[loves] My dog hates dog food </variable>
<variable class="loves">[loves] My *cat* hates**dog** food </variable>
<li class="loves">[loves] My dog loves dog food </li>

Can you try this?

(?<=\>)\[.*\].*(loves).*(?=\<)

Hello Peter,

There are some cases, where there’s no space
Input
<variable class="loves">[loves]loves dog food </variable>
Output
<variable class="loves">[loves]hates dog food </variable>

then list all samples/variations, so we can check for the individual specifics

Hi,

How about negative lookahead and negative lookbehind as the following?

System.Text.RegularExpressions.Regex.Replace(yourString,"(?<![\[""])loves(?![\]""])","hates")

With this expression:

(?<=\>)\[?.*\]?(loves).*(?=\<)

You should normally get all matches:
