RegEx with dynamic/varying length

DanAAC

Hi all,

 

I need to parse a long string that has some fixed and variable characters. 

For the fixed characters, I use (\w{#}), but for the variable characters I am looking for a solution.

 

For example, all the characters in the following string are fixed, except for the red characters, which can vary from 1-24 characters (including white spaces).

 

XXXX XXX X X X XXXXXXXXXXXXXXXXXXXXXXXX XX XX XX XXXXXXXX XXXXXXXX XXXXXX

 

Would appreciate any assistance!

If the black characters are always consistent, and assuming the leading there are 8 leading characters and 16 trailing characters something along these lines should work 

Right(Left([Code],Length([Code]) - 16),Length([Code]) - 24)

Here is a breakdown of the steps :)

Length([Field]) - 16

 

this will give you the length of the red characters and the leading characters

Left([Field], Length([Field]) - 16)

adding that to left will return the leading and the red characters

Right([Field], Left(Length([Field]) - 16),  Length([Field]) - 24)

stacking that with a right, will just bring out the red characters

@DanAAC Can you provide a sample data?

Thank you!

 

I am not sure this is what I am looking for. I am going to parse the ENTIRE string, not just the string in red. But the string in red is not fixed.

I am using RegEx to parse the string into columns.

Please see attached. It's essentially the same as in my original post. But I am using RegEx to parse one column that contains a string into multiple columns. The only problem is that the part in red is not fixed.
