By looking at my UnixUtils list which I have on my Windows machine I had found sed as well. :-)
Have been experimenting some with it but...

linbobo:~/sedtest# sed 's_<pre>_<post>_' <original.txt >new.txt
linbobo:~/sedtest# less new.txt

And indeed I will see <post> on that line instead of <pre> but...

linbobo:~/sedtest# sed 's_\n<pre>\n_\n<pre>\n\n_' <original.txt >new.txt
linbobo:~/sedtest# less new.txt

Will not create a new line after <pre> :-(
