Editing multiple files

I have a directory with hundreds of html files.
For all the files I have to:
- delete all the row from the beginning of the file to the sentence "<img src="immagini/_navDxBottom.gif" />".

- delete all the rows from the sentence "<br clear="right" />" to the end of the file.

How can I do that?
Thank you very much.

The easiest way to do those operations would either be a perl script or an awk script. I imagine if you're unfamiliar with both the awk would take less time to get right.

Here's one of the favorite tutorials on SED:

(The same site also has a good AWK tutorial.)

Look at the section on address ranges. For example, suppose you wanted to delete all lines, starting with a line containing "tweedledee" and ending with a line containing "tweedledum". The code would be:

sed '/tweedledee/,/tweedledum/d' filename > newfilename
