How to remove xml attributes in postgresql?

To remove XML attributes in PostgreSQL, you can use the xpath() function to modify the XML data. Here is an example of how you can remove an attribute from an XML column in a PostgreSQL table:

1. Update the XML column by removing the attribute:

1
2
3

UPDATE your_table
SET xml_column = xpath('/*/@attribute_to_remove', xml_column, '[]', 'true')
WHERE xpath('exists(/*/@attribute_to_remove)', xml_column, '[]', 'true');

Replace your_table with the name of your table and xml_column with the name of the XML column you want to modify. Also, replace attribute_to_remove with the name of the attribute you want to remove.

1. Verify that the attribute has been removed:

1
2

SELECT xml_column
FROM your_table;

This query will show you the updated XML data with the attribute removed.

Please note that these queries may need to be adjusted based on the structure of your XML data. Make sure to test these queries in a safe environment before applying them to your production database.
