DOMException
Synopsis
DOM operations may occasionally encounter a problem
and raise an exception. The abstract interface defined by the W3C
DOM specification defines one exception and several constants. In
this interface, specific exceptions are detected by catching the
general exception and checking the code attribute of the exception object.
Python extends this to behave more like other Python exceptions:
there is the DOMException base
class for the exceptions, and a derived class for each specific
exception. The code attribute
still takes one of the defined constants as a value. Code that is
expecting to deal with only one particular exception should only
name the specific derived exception in an except clause but code that expects to
handle any DOM exception in a general way should name the DOMException base class. All of the
exception classes and constants are defined in the xml.dom module.
In this list, the first name is the name of the exception
class, and the second name is the name of the constant for the
code attribute.
IndexSizeErr (INDEX_SIZE_ERR)Raised if an index of size is negative or greater than the allowed value.
DOMStringSizeErr (DOMSTRING_SIZE_ERR)Raised if the specified range of text does not fit into a
DOMString.HierarchyRequestErr (HIERARCHY_REQUEST_ERR)WrongDocumentErr (WRONG_DOCUMENT_ERR)Used if a node is used in a different document than the one that created it (which doesn’t support it).
InvalidCharacterErr (INVALID_CHARACTER_ERR)Used if an invalid or illegal character is specified, such as in a name. Illegal characters are indicated in the XML specification.
NoDataAllowedErr (NO_DATA_ALLOWED_ERR)Used if data is specified for a node that does not support data.
NoModificationAllowedErr (NO_MODIFICATION_ALLOWED_ERR)Used if an attempt is made to modify an object where modifications are not allowed.
NotFoundErr (NOT_FOUND_ERR)Used if an attempt is made to reference a node in a context in which it does not exist.
NotSupportedErr (NOT_SUPPORTED_ERR)Used if the implementation does not support the requested type of object or operation.
InuseAttributeErr (INUSE_ATTRIBUTE_ERR)Used if an attempt is made to add an attribute that is already in use elsewhere.
InvalidStateErr (INVALID_STATE_ERR)Used if an attempt is made to use an object that is not, or is no longer, usable.
SyntaxErr (SYNTAX_ERR)InvalidModificationErr (INVALID_MODIFICATION_ERR)Used if an attempt is made to modify the type of the underlying object.
NamespaceErr (NAMESPACE_ERR)Used if an attempt is made to create or change an object in a way that is incorrect with regard to namespaces.
InvalidAccessErr(INVALID_ACCESS_ERR)Used if a parameter or an operation is not supported by the underlying object.
