Macro to apply parsing rules for strings and list the substrings

Dear All,
I'm looking for detect and list the substrings (bellow cell "A3") for
a given string (on cell "A1") that must be generated for one or more
general rule(s). I have almost 100 different rules that can be applied
alone or together one to the other. Do you have any idea about how
could I do that? The rules are listed bellow and I put an example.

Rules:
According to these rules, letters in a string undergoing parse are
designated in the left or right direction from the parsed letter.
There are some exceptions related to the presence of one or more
letters sorrounding some specific point of parse.

Parsing rules:

Rule Parse where? Exceptions
1 Right side of K or R if P is Right to K or
R
2 Right side of K or R
3 Right side of K or R if P is Right to
K or R; after K in CKY, DKD, CKH, CKD, KKR; after R in RRH, RRR, CRK,
DRD, RRF, KRR
4 Right side of K
5 Left side of K
6 Right side of M
7 Right side of R if P is Right to R
8 Left side of D
9 Left side of D, Right side of K
10 Left side of D or E
11 Right side of E if P is Right to E, or if
E is Right to E
12 Right side of D or E if P is Right to D or
E, or if E is Right to D or E
13 Right side of D, E and K if P is Right to D or E,
or if E is Right to D or E
14 Right side of F, L, M, W, Y if P is Right to F,
L, M, W, Y, if P is Left to Y
15 Right side of F, Y, W if P is Right to F,
Y, W, if P is Left to Y
16 Right side of K, R, F, Y, W if P is Right to K, R,
F, Y, W, if P is Left to Y
17 Right side of F, L
18 Right side of F, L, W, Y, A, E, Q
19 Right side of A, F, Y, W, L, I, V
20 Left side of A, F, I, L, M, V if D or E is Left to
A, F, I, L, M, V

Luciano,

A lot of these simpler rules would be easy to implement

For example, rule 2

Function Rule2(strVal As String) As Variant
Rule2 = Application.Transpose(Split(Replace(Replace(strVal, "K", "K "), "R", "R "), " "))
End Function


If your string is in cell A1, your could select A2:A10 and enter using Ctrl-Shift-Enter

=Rule2(A1)

Other rules would require stepping through and checking each instance, but before I do an example of
that, if you could answer one question:

Is there a letter that will NEVER appear in your strings?

HTH,

Bernie,

OK, We will have just 20 types of letters:

A, C, D, E, F, G, H, I, K, L, M, N, P, Q, R, S, T, V, X

For some situations, I will have some new future rules and it is
possible that in several cases I will have to apply more than one rule
simultaneously.
Thanks in advance,
Luciano

I`m very happy that you said that a lot of the rules are simple to
implemnt. I have successfuly tested that one you send me.
Thank for your help with this.

You could implement each rule as a Regular Expression, and then select the
rule(s) you wish to apply.

For example, a routine with the Regular Expressions for rules 1,2,8,17 already
figured out for you, and which allows the application of multiple rules on a
given string, might look like the code below.

You select a cell which contains your string and then execute the macro. You
can enter one or more rules -- enter them by number <space> separated.

The macro will then apply each rule in order, and output the results in the
rows below your selected cell, skipping the row immediately below (so that if
your data is in A1, the strings will start in A3.

There are other methods of implementing your rules than Regular Expressions,
but with so many rules, this would be the simplest for me.

Dear Ron,
I had forgotten to say that in some circunstances it is necessary to
specify that the rule could avoid parse 1, 2, 3... of the letters.
For example, we have the string bellow and following a rule that parse
after K. If I specify the possibility of one (1) lost parsing, we
should have as result:

You didn't give any examples of what the results would be of these rules when
applied to a target string. By that I mean to do, as you did in your initial
posting, to give an example of the input string, and what you expect as output.

That makes it more difficult to debug.

But try this:

Rule 3:

"(CKY|DKD|CKH|CKD|KKR|RRH|RRR|CRK|DRD|RRF|KRR|[^KR]|[KR]P)+[KR]?|[KR]"

Rule 9:

"D?[^KD]+K?|[KD]"

It would just be a matter of combining the results from the array we generate.

Examining your example result, it appears as if you want to have both the
original output with the output relevant to the number of "skipped" parsing's
below it.

Since this is getting more complex, I have taken the liberty of also outputting
the rule(s) being used; and separating the original output from the output with
the "skipped" parsing's.

This has required some modifications so I am posting the entire macro as it
presently exists.

Eventually, it might be useful to input the parameters (rule(s) and number of
skips) via a user form, instead of multiple Input Box's as I've done so far.

You didn't give any examples of what the results would be of these rules when
applied to a target string.  By that I mean to do, as you did in your initial
posting, to give an example of the input string, and what you expect as output.

That makes it more difficult to debug.

But try this:

Rule 3:

"(CKY|DKD|CKH|CKD|KKR|RRH|RRR|CRK|DRD|RRF|KRR|[^KR]|[KR]P)+[KR]?|[KR]"

Rule 9:

"D?[^KD]+K?|[KD]"

I`m sending some examples of than, sorry...
Thanks in advance,

3 Right side of K or R if P is Right to K or R; except after K
in CKY, DKD, CKH, CKD, KKR; after R in RRH, RRR, CRK, DRD, RRF, KRR

I think these will do: (The others will have to wait, if you can't figure it
out).

Dear Ron,
I had forgotten to say that in some circunstances it is necessary to
specify that the rule could avoid parse 1, 2, 3... of the letters.
For example, we have the string bellow and following a rule that parse
after K. If I specify the possibility of one (1) lost parsing, we
should have as result:


Do you have any idea how to implement that in your script?
Thanks in advance,
Luciano

It would just be a matter of combining the results from the array we generate.

Examining your example result, it appears as if you want to have both the
original output with the output relevant to the number of "skipped" parsing's
below it.

Since this is getting more complex, I have taken the liberty of also outputting
the rule(s) being used; and separating the original output from the output with
the "skipped" parsing's.

This has required some modifications so I am posting the entire macro as it
presently exists.

Eventually, it might be useful to input the parameters (rule(s) and number of
skips) via a user form, instead of multiple Input Box's as I've done so far.

Dear Ron,
You are correct that it would be better to input the parameters (rule
(s) and number of
skips) via a user form, instead of multiple Box. It would be great to
select the rules and eventually skips. Could you help me with this?
Thanks in advance,
Luciano
