I'd use (and have used) perl to do this.  I had a template html file that
needed stats inserting at a certain point.

Not sure how good your perl is (hopefully better than mine) but the
structure should look a bit like this.

Read inputfile line
if inputfile line = starttag then {
	open insertfile
	read insertfile line by line
	write insert file lines to outputfile

	read input file until inputfile line = endtag #(this will skip to the end
of the bit to miss out)
      }
if inputfile line <> start tag and inputfile line <> end tag write inputfile
line to outputfile.

Hope this isn't too crypic.  I don't have time at the mo to put it in real
code and without testing I'd probably mix my php and perl together and leave
you with a load of useless code.

It can probably be done in a lot less code.  You have to get perl/sed etc to
match over multiple lines which I was never any good at and it took me less
time to code it in long hand than try to be clever and do it in a one liner.
