How can I get multiple info from different files
HI,

Supose I have these 2 files:

file1.txt
Name: John
Age:28
DateOfBirth:21/12/2004

file2.txt
Name: Thomas
Age:30
DateOfBirth:11/1/2003

I need to retrieve into a single file the "Name" and "DateOfBirth" from the 2 files, so the result looks like this:

file3.txt
John:21/12/2004
Thomas:11/1/2003

Regards
Elio
