Understanding the PostgreSQL Error Code: 2200L – not_an_xml_document

The PostgreSQL Error Code: 2200L – not_an_xml_document occurs when you try to parse or manipulate an XML document that is not well-formed or does not conform to the XML standards. This error typically arises when working with XML data types or performing operations that involve XML documents.

Possible Causes of the Error

Fixing the PostgreSQL Error Code: 2200L – not_an_xml_document

If there is a mismatch, convert the document to the correct encoding or adjust the encoding settings accordingly.

3. Verify Data Types
