When encountering the error 2200L: Not an XML Document in a PostgreSQL database, follow these immediate actionable steps:
xmllint for this purpose. For example:xmllint --noout yourfile.xml
yourfile.xml with the path to your XML document.SELECT your_xml_column FROM your_table WHERE some_condition;
your_xml_column, your_table, and some_condition with the actual column name, table name, and condition to locate the problematic XML data.SELECT xmlelement(name "test", 'This is a test');
'This is a test' with your XML content. If this query returns an error, the XML content is likely malformed.SELECT unnest(xpath('/path/to/element', '<root><element>test</element></root>'::xml));
/path/to/element and the XML string with your XPath expression and XML content accordingly.By following these steps, you should be able to identify and possibly rectify the issue causing the 2200L: Not an XML Document error in your PostgreSQL database.
