Error handling

Any of the methods listed above may fail, but this will not normally cause the Progress error status to be raised. Instead, the method will return FALSE if that is appropriate. Also, the parsing may encounter errors that do not cause the operation as a whole to fail. So instead of testing for ERROR-STATUS:ERROR after running a method with NO-ERROR, you should test for ERROR-STATUS:NUM-MESSAGES being greater than 0.

Note that the DOM parser may detect errors in an input XML document even if validation is not specified in the LOAD( ) method call. Validation checks the document for conformance to a DTD, but there could be other errors, such a missing end-tag or mismatched tags. The parser will report these errors independently of validation against a DTD.
