[TanTan]

Hi,

I have get the attached file details from command prompt.

I would like to know, is there any method can get the mac address string only? Which is "00-04-A3-12-32-25" and filter out the others detail.

Thanks.

Regex to the rescue.

You can just paste this regex into the constant for Match Regular Expression

([[:xdigit:]]{2}-){5}[[:xdigit:]]{2}

8.5 vi attached

Oh, thank you. My problem is solved.

Between, may i know where can i get the definition for all these regular expression? ([[:xdigit:]]{2}-){5}[[:xdigit:]]{2}

Thanks.

I always refer to this page:  www.pcre.org

In this case: ([[:xdigit:]]{2}-){5}[[:xdigit:]]{2} translates to:

Look for 2 hex digits followed by -, all repeated 5 times followed by two more hex digits.

Have a nice day.

Hi,

I have one more step to do. If I would like to filter out the '-' in between the number from attached vi. How can i do it?

Example:

From: 00-04-A3-12-32-25

To: 0004A3123225

Appreciate your feedback.

Thanks.

Use Search and Replace on the Mac address string, search for '-' and leave the replace string blank. Be sure to set Replace All to true.
