HTML Comment Removal

Remove erronous comments that prevent you from commenting out a block of HTML code. For instance a block like this would prevent you from commenting out anything after it because the existing comment will interrupt the new comment tags that will surround the content;

    <div class="foo">
        <li class="bar">Baz</li>
    </div>
    <!-- ./foo -->

This snippet will remove any and all HTML Comments in a document - Use with care. The additional brackets surrounding it may or may not be required, Doesn't seem to matter either way

This will search for lines that have a carriage return or a new line character at the very start of them and nothing after that. This will remove all blank lines from a document, Against use with care.
