Parse Mac Address with match regular expression

[Olivioloyer]

Hi Everyone,

I have a problem with the Match Regular Expression function,

I am trying to parse the response two a arp -a 192.168.0.15 request in order to extract MAC address of this remote IP, I used the following RegEx: ^([0-9a-fA-F]{2}[:-]){5}([0-9a-fA-F]{2})$

I am wondering why do I need to do a string subset first to extract only the MAC Address part. Isn't Match Regular Expression function capable of recognizing the RegEx directly in the middle of a string?

I only works when I extract the right tring subset as in the picture bellow.

Thanks for your answers.

Get rid of the "^" in the beginning of your regular expression. You are instructing it to find the pattern at the beginning of the string.

Hi Mark,

Thanks a lot for your answer, I did what you said, and I still see no change.

the answer from arp -a is :

Interfaz: 192.168.0.16 --- 0xb
  Direcci¢n de Internet          Direcci¢n f¡sica      Tipo
  192.168.0.15          00-04-7e-02-21-10     din mico  

and the whole match output gives nothing ""

OK found the answer I also must quit the $ at the end,

Thanks a lot Mark,

Have a great day

Sorry, I should have noticed the "$" as well. Glad it is working for you.
