+ autoinstall.py: Don't use an XML parser to parse HTML
+ https://bugs.webkit.org/show_bug.cgi?id=221162
+
+ Reviewed by Jonathan Bedard.
+
+ Very recently autoinstall.py started failing becagse the page returned
+ by https://pypi.org/simple/fasteners/ now contains a <meta> tag, which
+ is not parseable as XML without the trailing slash.
+
+ Despite what an initial fix in r272041 stated, this is not caused by
+ invalid HTML: <meta> tags are not required to have an ending slash to
+ be standards compliant in any version of HTML.
+
+ This patch replaces that code to use an HTML parser instead of an XML
+ parser, making it more robust.
