Here is a sketch, using -decode- temporarily. Might be a starting point.

cap prog drop foo
prog foo
	version 11.1
	tempname _strvar _i
	qui dec `: word 1 of `0'' ,g(`_strvar')
	qui g byte `_i' = strmatch(`_strvar', `"`: word 2 of `0''"')
	drop `_strvar'
	loc vars `vars' `: word 1 of `0''
	forval j = 3(2)`: word count `0'' {
		loc k = `j' + 1
		qui dec `: word `j' of `0'' ,g(`_strvar')
		qui replace `_i' ///
			= strmatch(`_strvar' ,`"`: word `k' of `0''"') ///
			if `_i'
		drop `_strvar'
		loc vars `vars' `: word `j' of `0''
	}
	l `vars' if `_i'
end
