Errors

Calling any of the data checkers (e.g. IntCheck, TextCheck) with invalid data should raise the expected exception. Calling an IntCheck with a string value of ‘fail’ should raise a ValueError, just as calling int(‘fail’) would in the intepreter.

The xcheck module defines the following execptions:

exception XCheckError

This is the root error, subclassed from Exception, and is used as the generic error in all xcheck objects.

exception MismatchedTagError

Occurs when the validator expected one tag, and got another.

exception UnknownAttributeError

Raised when a checker comes across an attribute of an element that it does not know about

exception AttributeError

Occurs for general XML attribute related issuse

exception UncheckedAttributeError

Occurs when an XML Element has an attribute the checker didn’t touch

exception MissingChildError

Raised when a required child element is missing

exception UnexpectedChildError

Raised when the checker encounters a child element it doesn’t know about.
