Problem:
A customer has a program that returns an XML status, but he cannot find out where these are documented.
Resolution:
The codes are documented in different places (depending on the product), but here they are for reference:
Return Code Meaning
> 0 After a successful READ action, the ordinal number of the record read is returned as the status code.
0 Success. The XML I/O action is performed without problem.
-1 The XML I/O action is trying to access an XML stream that is not opened.
-2 This is an invalid XML I/O action.
-3 Invalid mode is specified in the OPEN statement.
-4 The XML stream cannot be opened.
-5 The XML I/O action is attempting to access an internal DOM (Document Object Model) representation which is not present. DOM enables you to create and modify HTML pages and XML documents as full-fledged program objects.
-6 An invalid KEY is specified in the XML I/O action.
-7 The end of the XML stream has been reached .
-8 This is an invalid position to insert the specified XML item.
-9 The current record read is not a well-formed XML document.
-10 The internal DOM representation is not written out to any XML stream and has been cleared after a READ statement or a CLOSE statement.
-11 There is a problem reading an XML stream that is a URL.
-12 There is a problem writing to an XML stream that is a URL.
