13.5.5 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

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.
