Oxygen XML Forum

I've been able to do external validations in the past, but today when I tried it, I get the following error:

SystemID: http://www.w3.org/TR/html4/loose.dtd
Engine name: Xerces
Severity: fatal
Description: The declaration for the entity "HTML.Version" must end with '>'.
Start location: 31:3

Any idea what would cause this? Please let me know if more info is needed. Thank you

Hello,

Oxygen XML Editor can't validate HTML since it's not XML-based, it's SGML. However, it can edit and validate XHTML.

The DTD you are using for validation is the HTML 4.01 Transitional DTD, an SGML DTD which cannot be handled by Oxygen. Oxygen can only handle XML documents and XML DTDs/schemas.

Thank you for the prompt reply. The file I am trying to validate IS xml, not html. And I don't know what it is trying to validate against: http://www.w3.org/TR/html4/loose.dtd . I don't know what this "loose.dtd" is. Hope you can help. Thank you

Please post a sample XML file that we can use to reproduce the problem. You can cut parts from your file until you get to a minimum that still shows the issue.

Best Regards,
