You may want to try the two-address form. For example,
sed -e '/^OBJECT/,/^$/ s/STYLE="thisstyle"/STYLE="thatstyle"/' ...
would apply the change in blocks of lines where the first line of the
block starts with OBJECT and the last line of the block is empty.
Outside of such blocks, the change would not be applied.
