I have the large number of files in which the file's names follow certain pattern. for example here are names of two files
name1="event_No. 2_20140311_910_914.jpg" name2="event_No. 403_20140311_230727_230731.jpg"
I need to extract the last two numbers of the names to get something like this (String or Expression, it does not matter):
I tried StringTake but it is not supporting Rules and patterns.
can any one suggest some way to do this?
