relatively easy work-around:
from sqlalchemy.sql.functions import GenericFunction class XMLTypeFunc(GenericFunction): type=CLOB name='XMLType' identifier='XMLTypeFunc' from sqlalchemy.types import TypeDecorator from lxml import etree class XMLType(TypeDecorator): impl = CLOB type = 'XMLTYPE' #etree.Element def get_col_spec(self): return 'XMLTYPE' def bind_processor(self, dialect): def process(value): if value is not None: return etree.tostring(value, encoding='UTF-8', pretty_print='True') #return etree.dump(value) else: return None return process def process_result_value(self, value, dialect): if value is not None: value = etree.fromstring(value) return value def bind_expression(self, bindvalue): return XMLTypeFunc(bindvalue)

I realized that this might be a tall order since cx_Oracle doesn't support this data type.
