Subject: [PATCH] load xml as string from local file, fixes #3942

If the entity loader is disabled on a system, loading files, even from
the local file system, is considered as external to the running php
process, and thus not allowed by the libxml extension. Reading the file
contents and loading the xml as a string is a valid alternative however.
