Line 6 is a bunch of "meta" statements, all of which I show on a separate
line each in order to preserve the angled brackets. On all lines the angled
brackets have been preserved. The mismatched character is the slash of the
closing tag </head>. What could be wrong with it? And if it is, what about
fault tolerance?

That is not XML. It is HTML. You get a mismatched tag because the <link>
tag doesn't need closing in HTML, but in XML every single tag needs closing.

Use an HTML parser. I strongly recommend  BeautifulSoup but I think etree
has an HTML parser too. I am not sure..

Actually, I don't think etree has a HTML parser. And I would counter-recommend lxml if speed is an issue: BeautifulSoup takes a looooong time to parse a large document.
