Identifying the Symptom

When working with XML data in Supabase Database, you might encounter the error code 2200X. This error typically manifests when attempting to parse or manipulate XML data, and it indicates an issue with XML comment syntax.

Common Observations

  • Queries involving XML data fail to execute.
  • Error messages indicating invalid XML syntax.
  • Unexpected application behavior when processing XML data.

Exploring the Issue

The error code 2200X is associated with invalid XML comment syntax. In XML, comments are enclosed within <!-- and -->. Any deviation from this syntax can lead to parsing errors, resulting in the 2200X error code.

Understanding XML Comment Syntax

XML comments must not contain the sequence -- within the comment text. For example, <!-- This is a valid comment --> is correct, whereas <!-- This is an invalid -- comment --> is not.

Steps to Fix the Issue

To resolve the 2200X error, you need to ensure that all XML comments in your data adhere to the correct syntax. Follow these steps to fix the issue:

Step 1: Identify the Problematic XML Data

Review the XML data that is causing the error. Look for comments and check their syntax. Ensure that no comment contains the sequence -- within the comment text.

Step 2: Correct the XML Comment Syntax

Modify any invalid comments to adhere to the correct syntax. For example, change <!-- Incorrect -- comment --> to <!-- Correct comment -->.

Step 3: Validate the XML Data

Use an XML validator tool to check the entire XML document for any other syntax errors. This can help ensure that your XML data is well-formed and free of errors. You can use online tools like XMLValidation.com for this purpose.

Step 4: Test the Changes

After correcting the XML syntax, re-run your queries or application to ensure that the error is resolved. If the issue persists, double-check the XML data for any overlooked syntax errors.
