Database Software

Hi,

I try to store an XML file into a XMLTYPE column in a Table.While storing it is trying to parse the xml files.
But my XML files contains some External Entity References, because of that parsing failed. I want to store my xml file as such without any
strong validation against the dtd and entity reference, simple well formness is enough for me.By default XML DB Oracle Parser is configured in setValidationMode as
true.So I want to know two things

1) How to suppress DTD Validation though I have dtd doc type reference in my XML, I searched all oralce docs , all are explaining how to configure the
newly created parser using Java or PL/SQL, but I want change the default behavior of Oracle Parser which is used by XML DB for storing xml files in XMLTYPE Column

2) Similarly I have External Entity References entries in my XML like &myentiy;
I want to suppress this feature of resolving entities.

I have searched all oracle docs , I couldn't find answers for my question.
Could u please help me for this problem

Thanks in advance
