You can actually log in ascii directly if you add "encoding=ascii" to the
configuration line for the xml plugin.

I don't know of any public/finished tools that parse this xml yet.

If you just need a quick and dirty fix to read the hex try something like this.

$ cat snortxml-0410 at ...1824... | perl -e 'while(<>){foreach $m ($_ =~ /[0-9a-fA-F]{2}/g) { print chr(hex($m));} print "\n";}'
