Search by format

Hi,

Is it possible to search in the text by format ?
For example, there is a date in the text in the form of dd/mm/yyyy.
I need to find this fragment and determine that it is exactly the date (a la Excel - mask search "??/??/????")

Use RegEx
Example:
Code: Select all  Expand view  RUN
  cRegExDate := "[0-3][0-9][-|/|.][0-1][0-9][-|/|.][1-2][0-9][0-9][0-9]"
   ? HB_ATX( cRegExDate, "His date of birth is 20/10/1986, What is his age?" )
   // result "20/10/1986"

Are you programming for East Asian languages?
If you are confined to English and West European languages, all characters other than accented characters are represented by a single byte (and the same byte) both in ANSI and UTF8.
So, normal RegEx expressions should work with UTF8 text also, if you are not programming for Asian languages

That's not how I asked the question. :(
I am interested in a regular expression for a date of this format «06» April 2023 (months may be different)

Code: Select all  Expand view  RUN
local cRegEx := "[«][0-3][0-9][»]"
? hb_atx( cRegEx , "test this «23». working" )
 

Result : "«23»"
Note: These are not Unicode characters.
