  Validate XML Structure: Use an XML validator to check the overall structure of the XML document. Fix any issues related to malformed XML.
  Data Cleansing: If the XML is generated from a database or application, ensure that the data being inserted into the XML does not contain invalid characters. Implement data validation and cleansing processes as needed.
