I'm trying to parse following sentences with regex (javascript) :
Currently I'm trying : I(\b[a-zA-Z]*\b){0,5}(TV|chocolate|fire) but it doesn't work. I also made some test with \w but no luck.
I want to allow any word (max 5 words) between "I" and the last word witch is predefined.
To account for non-word chars in-between words, you may use
/I(?:\W+\w+){0,5}\W+(?:TV|chocolate|fire)/
See the regex demo
The point is that you added word boundaries, but did not account for spaces, punctuation, etc. (all the other non-word chars) between "words".
Pattern details:
I - matches the left delimiter(?:\W+\w+){0,5}\W+ - matches 0 to 5 sequences (due to the limiting quantifier {n,m}) of 1+ non-word chars (\W+) and 1+ word chars after them (\w+), and a \W+ at the end matches 1 or more non-word chars that must be present to separate the last matched word chars from the...(?:TV|chocolate|fire) - matches the trailing delimiter
