Error Codes
Expat Parsing Errors
The following constants are defined for expat parsing error. These are returned by xml_Parse and xml_ParseBLOB if an error occurs during parsing.
| 0 | XML_Err_None |
| 1 | XML_Err_NoMemory |
| 2 | XML_Err_Syntax |
| 3 | XML_Err_NoElements |
| 4 | XML_Err_InvalidToken |
| 5 | XML_Err_UnclosedToken |
| 6 | XML_Err_PartialChar |
| 7 | XML_Err_TagMismatch |
| 8 | XML_Err_DuplicateAttribute |
| 9 | XML_Err_JunkAfterDocElement |
| 10 | XML_Err_ParamEntityRef |
| 11 | XML_Err_UndefinedEntity |
| 12 | XML_Err_RecursiveEntityRef |
| 13 | XML_Err_AsyncEntity |
| 14 | XML_Err_BadCharRef |
| 15 | XML_Err_BinaryEntityRef |
| 16 | XML_Err_AttributeExtEntityRef |
| 17 | XML_Err_MisplacedXmlPI |
| 18 | XML_Err_UnknownEncoding |
| 19 | XML_Err_IncorrectEncoding |
| 20 | XML_Err_UnclosedCDATASection |
| 21 | XML_Err_ExternalEntityHandling |
| 22 | XML_Err_NotStandalone |
Expat4D Errors
Expat4D errors are normally caused by not using the plug-in correctly. Expat4D errors can be trapped by setting the Expat4D error handler using xml_SetErrorHandler. The first parameter of the error handler method receives a longint value which corresponds to one of the following constants.
| 0 | E4D_Err_None |
| 1 | E4D_Err_InvalidParserHandle |
| 2 | E4D_Err_InvalidHandlerMethod |
| 3 | E4D_Err_CannotCreateParser |
| 4 | E4D_Err_OutputBufferFull |
