DOMException instances carry a code attribute that provides the appropriate value for the specific exception.\n\nThe Python DOM interface provides the constants, but also expands the set of exceptions so that a specific exception exists for each of the exception codes defined by the DOM. The implementations must raise the appropriate specific exception, each of which carries the appropriate value for the code attribute.\n\nBase exception class used for all specific DOM exceptions. This exception class cannot be directly instantiated.\n\nRaised when a specified range of text does not fit into a string. This is not known to be used in the Python DOM implementations, but may be received from DOM implementations not written in Python.\n\nRaised when an attempt is made to insert a node where the node type is not allowed.\n\nRaised when an index or size parameter to a method is negative or exceeds the allowed values.\n\nRaised when an attempt is made to insert an Attr node that is already present elsewhere in the document.\n\nRaised if a parameter or an operation is not supported on the underlying object.\n\nThis exception is raised when a string parameter contains a character that is not permitted in the context it's being used in by the XML 1.0 recommendation. For example, attempting to create an Element node with a space in the element type name will cause this error to be raised.\n\nRaised when an attempt is made to modify the type of a node.\n\nRaised when an attempt is made to use an object that is not defined or is no longer usable.\n\nIf an attempt is made to change any object in a way that is not permitted with regard to the Namespaces in XML < recommendation, this exception is raised.\n\nException when a node does not exist in the referenced context. For example, NamedNodeMap.removeNamedItem will raise this if the node passed in does not exist in the map.\n\nRaised when the implementation does not support the requested type of object or operation.\n\nThis is raised if data is specified for a node which does not support data.\n\nRaised on attempts to modify an object where modifications are not allowed (such as for read-only nodes).\n\nRaised when an invalid or illegal string is specified. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
