The simplest solution is to just send the output to a file; you might want to copy the file beforehand so you don't have to overwrite the file you're reading (which might otherwise lead to undesired behavior).

cp test.html test.html.orig
awk 'your awk script here' test.html.orig >test.html
# and then optionally remove the copy:
rm test.html.orig
