you probably have some characters before/after the phrase that prevents
the match.
This should do it: (i hope)
/(\S|\s)*\bethyl\b(\S|\s)*/i

Hi Deniz,
I tried the referred regex tool as well,
and I get Bad Result for /^ethyl/i
and Good Result for /ethyl/i
Cor
Hi Deniz, Edward, Mike,
Thanks for your suggestions.
Deniz,
pattern /(\S|\s)*\bethyl\b(\S|\s)*/i
makes from any line containing ethyl, such as
Undenatured ethyl alcohol
lines containing only: >ethyl
Edward,
pattern /(\s|>)ethyl(\s|<)/i
makes from: Undenatured ethyl alcohol
Undenaturedethylalcohol (stripping spaces).
I will take a look at http://suda.co.uk/projects/SEHL/.
Mike,
the \W character
makes from Undenatured ethyl alcohol
Undenaturedethylalcohol (stripping spaces).
The \b character makes:
Undenatured ethyl alcohol (okay)
the word methyl is unchanged (okay)
but ethylene keeps also unchanged ...
Thanks anyway !
Cor
