  At the C level there is

xmlDtdPtr
xmlIOParseDTD(xmlSAXHandlerPtr sax, xmlParserInputBufferPtr input,
              xmlCharEncoding enc);

generating an xmlParserInputBufferPtr from a memory string is possible

with 

xmlParserInputBufferPtr
xmlParserInputBufferCreateMem(const char *mem, int size, xmlCharEncoding enc);

  so this is feasible in C. But there is no direct bindings for those in
Python, automatic mapping of Python I/O to xmlParserInputBufferPtr should
be doable, there is 

PyObject *
libxml_xmlCreateInputBuffer(ATTRIBUTE_UNUSED PyObject *self, PyObject *args)

in the python bindings, but xmlIOParseDTD is not part of the automatically
generated binding, though most of the infrastructure seems in place.
