I have got a string:
"Yoshimi Battles the Hip-Hop Robots"
The $keyword = hip
I count the substring before the $keyword like this:
string-length(substring-before($string, $keyword))
When I count the length before the keyword, it returning to me 0,
which is wrong.
Why is that wrong? If the spelling above is correct and not an error of
incorrect cut 'n' paste it is precisely what is should return: '0' when
the string is not found (which means: the string 'hip' that you are
searching for does not appear in the string).
