How to extract text from string using regular expressions

Hi,

I'm trying to use sed to extract some text and assign it to a variable.

Can anyone provide me with some help? it would be much appreciated!

I"m looking to extract for example:

filename=/output/R34/2005_13_R34_C1042S_T83_CRFTXT_20081015.txt

I'm trying to extract the 1042 from that file name.

Again any help would be appreciated!
