String pattern search

Hi

I am looking for a way to find whether a timestamp exists in a string..

The filename will be like this

rmaorder_palco_0060073508_20080228T063210.635Z.txt

where T is the seperator between date and time format.. can u tell me a way to filter the date and time from this string..

Is there any way I can check for a string pattern in this case where date and time are dynamically determined...

Will command CP help us out here
