Thank you for the replies monks! Here is a cut down example in response to wfsp's post.
The code to remove begins here:
        <?xml version="1.0" encoding="UTF-8"?>
        <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/
+xhtml1-strict.dtd">
        <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang=
+"en">

        <head>
            <meta HTTP-EQUIV="Content-Type" CONTENT="text/html; charse
+t=ISO-8859-1">

[download]

And it continues with a bunch of code I would like to remove. My end marker for removal would be here: 
                    </b>
                </div>
            </td>
        </tr>

        </table>

This bunch of code repeats numerous times in the file.
After this code-to-remove, I have the code I would like to keep, tags and all, untouched by any parsing or modification.

After this code-to-keep, begins the cycle of code-to-remove again, as above:
        <?xml version="1.0" encoding="UTF-8"?>
        <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/
+xhtml1-strict.dtd">
        <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang=
+"en">

        <head>
            <meta HTTP-EQUIV="Content-Type" CONTENT="text/html; charse
+t=ISO-8859-1">

and so on...
I was reading up on and trying some code found from the internet and this post (Thank you Martin for your post), but can't seem to have the code-to-keep untouched by the parser.

Thank you
