IMO, you're wasting a lot of time waiting for help. Write that piece of code and share it with us if you want.
If you need to compare two strings, a single loop with string slicing and an internal table with two or three fields should help.
Pseudocode: Given string1 and string2 get a list of differences
Get the shorter string length (the other one has differences from the maxlength till the end of the string).
Maxlength = strlen(string1)
If maxlength > strlen(string2)
Maxlength = strlen(string2)
Endif
Currpos = 0
While currpos <= maxlength
Add 1 to currpos.
If string1+currpos(1) = string2+currpos(1) // String slicing
" you have a match? nothing to do.
Else.
"you have a difference at position currpos ->
Wa_Itab-currpos = currpos
Wa_Itab-instring1 = string1+currpos(1)
Wa_Itab-instring2 = string2+currpos(1)
Append wa_itab into itab.
Endif.
Endwhile
With a similar analysis you can get rid of different string lengths.
That's an idea? Once you're done, looping at itab should give you an idea of the differences and the position. Play a bit more an you'll get the idea for that FM.

Subject: ABAP Code to Highlight Differences Between Two Words
Thank you Soeren,
But this function module does a basic comparison of two strings, and returns only FALSE or TRUE.
I need a much more sophisticated comparison for 2 words, like this one:
http://www.raymondhill.net/finediff/viewdiff-ex.php
Or like this one: http://myerslab.mpi-cbg.de/wp-content/uploads/2014/06/np_diff.pdf .
These two examples are far too complex for me to be translated in ABAP!
So, if someone has such a comparison of two words in ABAP, thank you to share! |
