parsing problem

[Bernard Fay <bernard.fay@gmail.com>]

Hi,

I have long strings to parse which have permanent and variable information.  Somewhere in the strings we have something like  ".... Handle: 0x12a7 ....".  Handle is permanent and 0x12a7 is variable.  I wish to be able to extract the variable part (0x12a7) and assign it to a variable.  

Does anyone have an idea how to extract this information?

I think awk might be the tool to use but I not too good at it yet. 

Thanks,

Bernard
