Possibly related: when I tried to convert html to txt a few years ago, I
would find large comment tags that would go across several lines (new
lines within the comment tag). It turns out that these tags had embedded
javascript within it. Embedding the javascript within a comment tag
meant that a browser which could not deal with javascript would just
ignore it.
To strip out such tags, somebody wrote a tag stripper that could handle
tags where the tag start ("<") and tag end (">") were not on the same line.
