Subject: [gentoo-user] Any 'sed' geniuses out there?

I'm writing a sed script that will parse the *broken* output of
man2html. I say broken, because the output isn't W3C compliant (html
OR xhtml). I'd like to be able to modify it so that the final outcome
is XHTML 1.0 compliant. I'm running into a problem where the output
doesn't close the <p>, <dt>, or <dd> tags. XHTML requires that tags
containing text be closed. So the problem I'm having is being able to
take note of the starting tag, grab the subsequent paragraph, then
insert the closing tag. What I've got /sort of/ works, but still not.

Here's a sample that has been parsed, but not with the <p> modifying
elements:

<p>

Regular expression support is provided by the PCRE library package,
which is open source software, written by Philip Hazel, and copyright
by the University of Cambridge, England.  See <a
href="http://www.pcre.org/">http://www.pcre.org/</a> .

<p>

Nmap can optionally link to the OpenSSL cryptography toolkit, which is
available from <a
href="http://www.openssl.org/">http://www.openssl.org/</a> .


Here's the entire sedscr (sans comments):

/^$/{
        N
        /^\n$/d
}
/^Content-type: text\/html/c\

        s%\n%%
}
s%<[IB]>%\L&%
s%<\/[IB]>%\L&%
/<body>/,/<\/body>/{
        /<p>/!{
                H
                d
        }
        /<p>/{
                x
                s/$/<\/p>/
                G
        }
}
/^<p>$/,/<\p>$/{
        N
        /^\n<p>$/d
}


Here's the funkiness after parsing with the last part
(/<body>/,/<\/body>/{) enabled:

(Just in case you were wondering, this IS from the nmap man page. ;-)
Thanks.
