8.5.5 Expat error constants


8.5.5 Expat error constants

The following constants are provided in the errors object of the xml.parsers.expat module. These constants are useful in interpreting some of the attributes of the ExpatError exception objects raised when an error has occurred.

The errors object has the following attributes:

XML_ERROR_ASYNC_ENTITY

XML_ERROR_ATTRIBUTE_EXTERNAL_ENTITY_REF
An entity reference in an attribute value referred to an external entity instead of an internal entity.

XML_ERROR_BAD_CHAR_REF
A character reference referred to a character which is illegal in XML (for example, character 0, or `�').

XML_ERROR_BINARY_ENTITY_REF
An entity reference referred to an entity which was declared with a notation, so cannot be parsed.

XML_ERROR_DUPLICATE_ATTRIBUTE
An attribute was used more than once in a start tag.

XML_ERROR_INCORRECT_ENCODING

XML_ERROR_INVALID_TOKEN
Raised when an input byte could not properly be assigned to a character; for example, a NUL byte (value 0) in a UTF-8 input stream.

XML_ERROR_JUNK_AFTER_DOC_ELEMENT
Something other than whitespace occurred after the document element.

XML_ERROR_MISPLACED_XML_PI
An XML declaration was found somewhere other than the start of the input data.

XML_ERROR_NO_ELEMENTS
The document contains no elements (XML requires all documents to contain exactly one top-level element)..

XML_ERROR_NO_MEMORY
Expat was not able to allocate memory internally.

XML_ERROR_PARAM_ENTITY_REF
A parameter entity reference was found where it was not allowed.

XML_ERROR_PARTIAL_CHAR
An incomplete character was found in the input.

XML_ERROR_RECURSIVE_ENTITY_REF
An entity reference contained another reference to the same entity; possibly via a different name, and possibly indirectly.

XML_ERROR_SYNTAX
Some unspecified syntax error was encountered.

XML_ERROR_TAG_MISMATCH
An end tag did not match the innermost open start tag.

XML_ERROR_UNCLOSED_TOKEN
Some token (such as a start tag) was not closed before the end of the stream or the next token was encountered.

XML_ERROR_UNDEFINED_ENTITY
A reference was made to a entity which was not defined.

XML_ERROR_UNKNOWN_ENCODING
The document encoding is not supported by Expat.

XML_ERROR_UNCLOSED_CDATA_SECTION
A CDATA marked section was not closed.

XML_ERROR_EXTERNAL_ENTITY_HANDLING

XML_ERROR_NOT_STANDALONE
The parser determined that the document was not ``standalone'' though it declared itself to be in the XML declaration, and the NotStandaloneHandler was set and returned 0.

XML_ERROR_UNEXPECTED_STATE

XML_ERROR_ENTITY_DECLARED_IN_PE

XML_ERROR_FEATURE_REQUIRES_XML_DTD
An operation was requested that requires DTD support to be compiled in, but Expat was configured without DTD support. This should never be reported by a standard build of the xml.parsers.expat module.

XML_ERROR_CANT_CHANGE_FEATURE_ONCE_PARSING
A behavioral change was requested after parsing started that can only be changed before parsing has started. This is (currently) only raised by UseForeignDTD().

XML_ERROR_UNBOUND_PREFIX
An undeclared prefix was found when namespace processing was enabled.

XML_ERROR_UNDECLARING_PREFIX
The document attempted to remove the namespace declaration associated with a prefix.

XML_ERROR_INCOMPLETE_PE
A parameter entity contained incomplete markup.

XML_ERROR_XML_DECL
The document contained no document element at all.

XML_ERROR_TEXT_DECL
There was an error parsing a text declaration in an external entity.

XML_ERROR_PUBLICID
Characters were found in the public id that are not allowed.

XML_ERROR_SUSPENDED
The requested operation was made on a suspended parser, but isn't allowed. This includes attempts to provide additional input or to stop the parser.

XML_ERROR_NOT_SUSPENDED
An attempt to resume the parser was made when the parser had not been suspended.

XML_ERROR_ABORTED
This should not be reported to Python applications.

XML_ERROR_FINISHED
The requested operation was made on a parser which was finished parsing input, but isn't allowed. This includes attempts to provide additional input or to stop the parser.

XML_ERROR_SUSPEND_PE
