Matching long hex a strings

gman has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

As my regex skills are greatly lacking and I could not find a suitable solution that got my brain to jump start on it own, I'm having trouble matching a hex number like 01940110d840fc48. It could be contained in strings like the following examples.

_I_I_012c0110d840cc67 [call_process_result] <<<<<<<<<<<<stop interpret
+ator
INFO: Main menu CED is 1  Time: 36683996 ConnID 012c0110d840cc67
_C_W_012c0110d840cc67 [get_option_aux] there is no any value for optio
+n strategy0x1
[download]

What I have tried so far matches on all or nothing.
Thanks in advance for the help!

Edited, 2 Feb 2004, by footpad: Added <code> tags around sample data and XML-ified the HTML formatting. Also, corrected minor typos.

Many thanks to borisz and Abigail for the quick response and solutions.

Thanks!

Match the string `/([0-9a-f]{16})/i` if it is 16 chars long. Boris	[reply] [d/l]
