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.
