From d6b27d3e4c40946efa79e91d134616b41b1666c4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] LSN-2014-0003: Don't expand entities when parsing XML
If the XML_PARSE_NOENT flag is passed to libxml2, then any
entities in the input document will be fully expanded. This
allows the user to read arbitrary files on the host machine
by creating an entity pointing to a local file. Removing
the XML_PARSE_NOENT flag means that any entities are left
unchanged by the parser, or expanded to "" by the XPath
APIs.
