I think in that case you want to use the sed commands ``n'' and ``N''
for appending the next line into the pattern space. See a better
explanation here[1]. So if you are confident that they will be on
adjacent lines, you can have something like (I'll just quote the sed
script, as if you'd put it in a file):

/<body>/ {
  /<center>/ {
