Intuitively, I think there must be many people wanting to parse through text, so some solution must already exist. That is, find x, then from there find y (not just another occurrence of x). I have been writing custom code for each instance, but this is kind of what I would want. Is there a better way?

; Checks if a string contains a given substring, starting at a specified character position.
; Submitted by dogsurfer 2008-02-09.

; Syntax:  StringInStr2 ( "string", "substring" [, casesense [, occurrence [, start]]] )
; where start is the position from the left, regardless if occurrence is negative.

Func StringInStr2($string, $substring, $casesense = 0, $occurrence = 1, $start = 0)
    If $occurrence > 0 Then
        $string = StringTrimLeft($string, $start)
    Else
        $string = StringMid($string, 1, $start)
        $start = 0
    EndIf
    $position = StringInStr($string, $substring, $casesense, $occurrence)
    If $position > 0 Then Return $position + $start
EndFunc


$pos = 12; parsing example
$result = StringInStr2('I like Annette Funnicello', 'nn', 0, 1, $pos)
MsgBox(0, "StringInStr2 Forward Search Result", "The 'nn' in 'I like Annette Funnicello' starting from " & $pos & " is " & $result)

$result = StringInStr2('I like Annette Funnicello', 'nn', 0, -1, $pos)
MsgBox(0, "StringInStr2 Backward Search Result", "The 'nn' in 'I like Annette Funnicello' reversing from " & $pos & " is " & $result)

I would just use StringInStr to find your "x", then trim left of that and StringInString for "y".

Although you could probably use a regex to simplify this process with a single line of code.

There it is: StringRegExp! It more exactly gets to what I'm trying to parse. Not overly intuitive though.

I consider it obscure when code can be written by using a spoon in bowl of alphabet cereal.

There is an old saying, You cant have your code, and eat it too. Approximately. Thanks for your help!
