Hello frnz,

I have string  like "e59ff020        [e59ff020]:  00000000     ...."

I want the only 00000000 as my output.. whole content from start to end may vary with different contents but before the required output we can match colon and 2 spaces [:  ]

I am new to this TCl scripting language   ,  Could any one of you give me program for this?

Thanks a lot in advance.  

Yash

I think you need something like:

Code:

set inval {e59ff020        [e59ff020]:  00000000     ....} regexp {:  ([0-9]+)} $inval all part puts $part

Thank you Graham,  

I am facing one more problem now.
Actually i am geting below output from one of the expression like set inval [dw $yash_dfar 1]
( dw is the proc written which returns output as below)

e59ff020 [e59ff020]: 0000a0F0 ....

Below program which you have given will work only when we assign group of characters to inval manually.

regexp {: ([0-9]+)} $inval all part

So i want program for this,

======================================

Also comparision data should compare for A-F or a-f,

Could you please give me solution for this...

Thanks a lot in advance

Once you've got a string in a variable, it shouldn't matter where it came from, so the trick / problem really isn't just "manually assigned works". Perhaps you have som tab characters in your incoming string?

In a regular expression character group you can add whatever you need in the square brackets - e.g.  [0-9a-fA-F].   Looking at your original post, it wasn't clear to me that you were matching hex zeros - they looked very much like decimal zeros to me
