This should work as long as the pre block does not contain another pre block:
$ awk 'BEGIN {RS="\a"; FS="pre>"} { print "<pre>" $2 "pre>" }' input.html
The record separator (RS) should be some character that is not in the
file (above I use the audible bell). It is possible to do in sed, but
it would be a very long command line.
As pointed out by others, the real solution is not a one-liner but
using an HTML or XML parser.
