String to array using 2 different delimiters

String to array using 2 different delimiters

Postby ukoenig » Fri Aug 09, 2019 12:59 pm

Hello,

what is the best solution to build a structured array from a textline with 2 delimiters ?

maybe a char replace of < - > with blancs
next splitting the line for < ; >
and splitting blancs :?:

Delimiter Fields < ; >
Delimiter Fieldinfos < - >

Code: Select all  Expand view

FIRST-C-20-0;LAST-C-20-0;STREET-C-30-0;CITY-C-30-0;HIREDATE-D-8-0

the wanted result
DBF-structure

FIRST       C   20  0
LAST        C   20  0
STREET      C   30  0
HIREDATE    D    8  0
 


regards

Code: Select all  Expand view
  cText    := "FIRST-C-20-0;LAST-C-20-0;STREET-C-30-0;CITY-C-30-0;HIREDATE-D-8-0"
   aData    := HB_ATokens( cText, ";" )
   AEval( aData, { |c,i| aData[ i ] := HB_ATokens( c, "-" ) } )


This is optional. Converts character values to numbers, dates, etc., as may be appropriate. This may or may not give the expected results in all cases.

Code: Select all  Expand view
  for each aRow in aData
      AEval( aRow, { |c,i| aRow[ i ] := uCharToVal( c ) } )
   next

Mr. Rao,

thank You very much for Your help

this solution is needed for the second new part of the CSV-tool
to convert CSV to DBF
using CSV headlines optional with or without fieldsize / type - infos.

after building the CSV-headline from inside the first toolpart
I added a xBrowse-stop for the test
works perfect :D

best regards

FIRST-C-20-0;LAST-C-20-0;STREET-C-30-0;CITY-C-30-0;HIREDATE-D-8-0


Now this extra data for the headers is put inside the csv file with a editor ?

Marc,

these extra data ( fieldtype and size ) are included
creating a CSV from any DBF with section 1( DBF to CSV )
Reading this created CSV a DBF can be created with section 2 without any extra work.

In section 2 ( CSV to DBF ) it will be possible to add missing types and sizes
of the CSV created with other programs like Excel.
After that the DBF can be created.
I can add a test to check for missing values.

I will try to make it easy to manage.
