offset
Syntax
offset(<needle>, <haystack>[, <skipCharacters>])
put offset("Hell", "Say hello!") into probablyFive
put offset("Needle", field "Haystack", gLastFoundPos + length("Needle")) into nextSearchResult
Explanation
The offset
function finds the string <needle>
in the string <haystack>
and returns
the position of the character so that it can be used to access the first character of the
found word with the character
chunk expression.
It returns 0 if the requested needle string could does not occur in the haystack string.
If you specify skipCharacters, offset
will skip that many characters at the start of the
haystack string before it starts searching. This allows you to search for the next result
after you’ve found something, by doing something like:
put offset("Candy", field "Products") into firstResultPos
put offset("Candy", field "Products", firstResultPos + 1) into secondResultPos
Note that the position returned starts at 1 after the skipped characters. So you will have to add skipCharacters to the result to obtain the character number where the second search result starts.
