Delete characters that exceed the number of characters between the 11th and 12th occurence of "

Cristian Tanasa

Hello everyone,
I have many lines, which look like this:

“TRX_TT_ID”;“TRX_APP_DD”;“ORIGIN”;“SUB_TYPE”;“NUMBER”;“TABLE_TRX_LNR”;“DATABANK_NUMBER”;“STATE”;“CVBT_ISO_LKZ”;“PRODUKT”
“1000”;“1”;“1”;“”;“834600000”;“13340000 2227”;“1082803 / 13341837 2227”;“1”;“EN”
“1000”;“1”;“1”;“”;“834600000”;“13350001 33 This is very long and needs to be truncated”;“1080668 / 13341845 This is technical”;“1”;“EN”;“Call”

The text between occurence no. 11 and 12 of " needs to be trimmed after the first 10 characters (that column must have maximum 10 characters).

Can anyone please help out?
Thank you!
Cristian

Hello, @Cristian-tanasa, and All,

There still are some points not totally clear !

Firstly, I suppose that you’re using regular double quotes " and not the “ and ” characters !
Secondly, from the header line, each row of your table should contain 10 fields. Apparently, it’s not the case of your first line, which contains 9 fields !
Thirdly, if we keep the first 10 characters, only, of the 6th field concerned, we get the string 13350001 3 ! Do you expect such result ?

In case of a positive result :

Open the Replace dialog ( Ctrl + H )
- SEARCH (?-s)^(?:"([^";\r\n])*";){5}"(?1){10}\K(?1)+(?=")
- REPLACE Leave EMPTY
- Tick the Wrap around option
- Select the Regular expression search mode
- Click on the Replace All button ( Do not use the Replace button ! )

=> All characters, of the 6th field, after the 10th character, are deleted !

If a row contains a 6th field with less than 11 chars, the line is not processed !

Hi, @Cristian-tanasa, and All,

I improved and generalized the process with these 8 new search regexes, in order to find part of a particular field n

Of course, I assume that :

Each row of the table contains the same number of fields
The field delimiter is the double quote char ( " )
The field separator is the semicolon ( ; )
Any field is preceded and/or followed with a ;
Any char, within a field, is different from, either, a " and a ; chars

Here are these generic regexes :

(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} "          \K (?1)*          #  ALL chars, even NONE,                     of FIELD n
(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} " (?1){#}  \K (?1)*          #  ALL chars, even NONE, AFTER the #th char  of FIELD n
(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} " (?1){#}  \K (?1){p}        #  p chars,              AFTER the #th char  of FIELD n
(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} "          \K (?1){p}        #  The p FIRST chars                         of FIELD n
(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} " (?1)*    \K (?1){p} (?=")  #  The p LAST  chars                         of FIELD n
(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} "          \K                #  EMPTY string, at BEGINNING                of FIELD n
(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} " (?1){#}  \K                #  EMPTY string, AFTER the #th char          of FIELD n
(?x) ^ (?: " ( [^";\r\n] )* " ; ) {n-1} " (?1)*    \K                #  EMPTY string, at END                      of FIELD n

Notes :

Let f be the total number of fields and let m be the maximum number of characters of the field n. Then :
- The variable n is between the values 1 included and f included ( So n-1 is in range [0,f-1] )
- The variable # is between the values 0 included and m included
- The variable p is between the values 0 included and m included

Let’s test these 8 real regexes, below :

(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  "          \K (?1)*          #  ALL chars, even NONE,                     of FIELD 6
(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  " (?1){10} \K (?1)*          #  ALL chars, even NONE, AFTER the 10th char of FIELD 6
(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  " (?1){10} \K (?1){3}        #  THREE chars,          AFTER the 10th char of FIELD 6
(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  "          \K (?1){5}        #  The 5 FIRST chars                         of FIELD 6
(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  " (?1)*    \K (?1){7} (?=")  #  The 7 LAST  chars                         of FIELD 6
(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  "          \K                #  EMPTY string, at BEGINNING                of FIELD 6
(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  " (?1){10} \K                #  EMPTY string, AFTER the 10th char         of FIELD 6
(?x) ^ (?: " ( [^";\r\n] )* " ; )  {5}  " (?1)*    \K                #  EMPTY string, at END                      of FIELD 6

Against the following sample text :

                           Field 6
                               V
