I am using this regex to match words in an html page.
\b(wordtosearch)\b(?!')
The forward negative lookhead is to prevent matching words having ' like don in don't
however i also want to match words that may or may not have s or ed at the end.
like if i have to search for test then it should match tests or tested.
Also please note that wordtosearch can contain many words seperated with | sign i.e car|truck
i realize that it would require a positive lookahead but i dont know how to make all this work.
(wordtosearch)(s|ed)? would do the trick. It will check that the search word is followed by optional s or ed suffix.
Example:
/\b(test)(s|ed)?\b(?!')/.test('tested')
