sed query linked http files

This is basic query to search all classic file links in html file:

sed "s/\d034/\n/g;s/\d039/\n/g;s/\d040/\n/g;s/\d041/\n/g;" index.html | sed -n "/http/p" > out.log

\d034 stands for " character.
\d039 stands for ' character.
\d040 stands for ( character.
\d041 stands for ) character.
