DLAs in the website: some updates and issues

Dear Debian LTS team
Thanks for your work adding the DLA advisories to the website.

I have created an usertag to group the bugs related to the "lts" section of the 
website:

https://udd.debian.org/cgi-bin/bts-usertags.cgi?user=www.debian.org%40packages.debian.org&tag=lts

It seems that the parse-dla.pl script sometimes does not put the closing </li>, 
</p> or </ul> tags in the correct place, or introduces weird HTML tags (look for 
"HTML fix" in the commit logs from last days for some examples).

I don't know if this is a bug or just some corner cases that would require much 
effort to catch in the script, so I didn't open a bug for now.

My proposal would be that the people parsing the advisory checks the generated 
wml file(s) prior to commit. I see that the proposed workflow in 
https://wiki.debian.org/LTS/Development#Publishing_updates_on_the_website 
includes the line

$EDITOR 2019/dla-123-1* # make sure everything looks good

Other option is, instead of looking at the html code, doing

make dla-123-1.en.html

and open the resulting html file with a web browser.

If after reviewing several files you feel there is certain pattern producing the 
bad HTML, maybe we can improve the Perl script or the current format of the 
advisories to avoid the issues in the future.

Kind regards,
