If you don't mind posting it publicly, please share the document you are trying to upload to Validate so we can take a look. It sounds like it's probably not a .xml file.

Hi. I actually managed to convert it and solve the validation issue. Thanks.

Now another error while trying to load on my organization ODK Aggregate is as below

HTTP Status 400 - Problem with JavaRosa Parsing Form: org.opendatakit.aggregate.exception.ODKIncompleteSubmissionData: Javarosa failed to construct a FormDef. Is this an XForm definition?

Hate to ask the obvious question, but are you uploading an XForm definition (e.g., form.xml) or an XLSForm (form.xls). If you are uploading an XLS file, it won't work. Needs to be XML.

Hi. Thank you it was an XML form and I got the error. It was actually a constraint with an issue.
