Line offset of an item (and other similar functions).

I don't think the standard handlers / libraries / commands can do this
for me, but I can always hope I missed it.
I have a data structure consisting of multiple lines, each of multiple
I want to find the line number which contains a particular item; the
item can be at any item position within the line.
I do want to match only whole items, so as to avoid false positives
(i.e. item "alex1" should not match "alex123")
lineOffset will give me the line number - but there's no way to say
"match whole items only"
itemOffset will find the right instance (given wholeMatches set to
true), but it gives me item number, not line number
matchChunk will find it for me - but gives character positions, not line
I'm hoping there's some way to inveigle one of the 'offset' functions to
Alternatively is there some way to convert chunk expressions between
given myVar containing
> 12, 34, 56
convert an expression such as item 3 to 5 of myVar to the
corresponding char/word/line expression (i.e. char 9 to 17 or word 1 to
3 or line 1 to 2).
Any suggestions on how to do it ?
If I submit an enhancement suggestion - do you think it should be for
the wholeItemMatch approach or the convert-chunk approach ?
