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 :mod:`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.
