But what I got is:

(gdb) p *child
$8 = {_private = 0x0, type = XML_ENTITY_REF_NODE, name = 0x9f83d20
"ent4", children = 0x9f7d210, last = 0x9f7d210,
  parent = 0x9f83ad0, next = 0x0, prev = 0x9f83ff0, doc = 0x9f7b450, ns = 0x0,
  content = 0x9f7d260 "<entElement domestic='Yes'>Element
data</entElement><?PItarget PIdata?>", properties = 0x0,
  nsDef = 0x0, psvi = 0x0, line = 0, extra = 0}
(gdb) p *child->children
$9 = {_private = 0x0, type = XML_ENTITY_DECL, name = 0x9f7b086 "ent4",
children = 0x0, last = 0x0, parent = 0x9f7b5a0,
  next = 0x9f7d2b0, prev = 0x9f7b740, doc = 0x9f7b450, ns = 0x9f7d078,
  content = 0x9f7d260 "<entElement domestic='Yes'>Element
data</entElement><?PItarget PIdata?>", properties = 0x47,
  nsDef = 0x1, psvi = 0x0, line = 0, extra = 0}
(gdb)

I use libxml2.6.26 and libxml2.6.31, which version do you use? And my
parser options are:
        ret = xmlCtxtUseOptions(parser->xml_ctx, XML_PARSE_DTDATTR ||
                        XML_PARSE_DTDLOAD || XML_PARSE_DTDVALID);

Thanks!
