From 3d0adda7560137309be8b10c63ff41e41dfb1516 Mon Sep 17 00:00:00 2001
From: =?UTF-8?q?Petr=20P=C3=ADsa=C5=99?= <ppisar@redhat.com>

Subject: [PATCH] Parse an ampersand entity in SAX interface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
After disabling parsing external entities in XML-LibXML-2.0202,
XML::LibXML::SAX interface stopped expanding &amp; and &#38; entities
in attribute values (often found in href XHTML attributes) and
returned "&#38;" instead. This was discovered by a RDF-Trine test
suite failure <https://github.com/kasei/perlrdf/issues/167>.
First, I suspected XML-LibXML
<https://rt.cpan.org/Ticket/Display.html?id=131498>, but it turned out
that the unexpanded entity comes from libxml2 C library itself. And
that it's not just an ommitted expansion, but that it's actually an
escape sequence for "&" characters. Other XML metacharacters (like
"<") are not affeced. Also text nodes are also not affected. My
finding was confirmed by an old libxml2 bug report
<https://bugzilla.gnome.org/show_bug.cgi?id=316487>.
This patch "fixes" this discepancy by replacing all "&#38;"
subtstrings with a literal "&" in SAX interface of start_element()
callbacks.
