regular exp

[tinnitus]

Hello all,

Thanks all for serie of suggestions

I went to regexp cause "nn.nn" could be "open" if probe is not connected so it was a manner to 

manage this exception. here three possible messages :

\s\s26.41\s\s\s\sopen\00\s\n

\s\sopen\s\s\s\s25.42\00\s\n

\s\sopen\s\s\s\sopen\00\s\n

Regards

big erratum right ones are

\s\s26.41\s\s\s\s25.42\s\n

\s\s26.41\s\s\s\sopen\00\s\n

\s\sopen\00\s\s\s\s25.42\s\n

\s\sopen\00\s\s\s\sopen\00\s\n

That's quite different from the original post 😉

Here's a quick example of code to extract those string values.  Since I have no clue what you will be doing next, I placed them into a 2-D array.  Depending on what you do next, there may be better ways of implementing the code.

It still uses Scan from String.  I'm sure an elegant solution can also be done using regular expressions.

I think my head is about to explode.

Of course, this always seems to happen whenever I look at regex.

After looking at these possible messages I think you should definitely go with the Scan from string function. LabVIEW do not support NULL character \00 in regex matching, you will get error -4702 (so sad, regex are so cool).

Don't let that stop you.

Obviously you can filter out the NULL character but you then have to use 2 functions to achieve the same result as the Scan from string function.

yes and no,

i mention "open" but  i forgot \00

the buffers given were 4 differents buffers depending if all (2) sensors are presents or not

Thank you for all detailed examples
