xhtml pages broken

[cweiske]

My blog serves pages with the application/xhtml+xml MIME type, which means browsers use
the XML parsing mode and do not try to render anything if the XML is not well-formed.

The internet archive software sends out this header for my page, too - but it adds HTML to the top of the page which is not well-formed according to the XML rules.

For example: https://web.archive.org/web/20170606065241/http://cweiske.de/tagebuch/cacert-bye.htm

Firefox 55 and Chromium 60 both stop rendering and show an error:

Chromium:

This page contains the following errors:
error on line 141 at column 43: Opening and ending tag mismatch:
br line 0 and div

Firefox:

XML processing error: Non matching tag. Expected:
.
Adress:
https://web.archive.org/web/20170606065241/http://cweiske.de/tagebuch/cacert-bye.htm
Line 141, Column 39:
Web wide crawl number 16<div><br></div><div>The seed list for
Wide00016 was made from the join of the top 1 million domains from
CISCO and the top 1 million domains from
Alexa.</div><div><br><div><br></div><div><br></div></div>

One way to fix that bug would be to make your embed code XHTML-compatible.
