Actually, the file format Ethereal captures in, by default, is libpcap 
format, which can also be read by Tethereal (not a surprise, as it uses 
the same code), tcpdump, and various other programs that can read 
libpcap files.  Perl has a Net::Pcap package in CPAN that can read 
libpcap files; other scripting languages might have libpcap support as well.

However, what you get when you read that file is raw packet data.  You 
have to parse all the packet data yourself.

File -> Export -> as Plain Text file.

That'll write out the summary list of packets, or the detailed 
dissection of all packets.

There's also

File->Export->as "CSV"
File->Export->XML - "PSML"
File->Export->XML - "PDML"

which might be better formats for a script to process.
