The basic error all other RSS errors stem from. Rescue this error if you want to handle any given RSS error and you don’t care about the details.
The InvalidRSSError error is the base class for a variety of errors related to a poorly-formed RSS feed. Rescue this error if you only care that a file could be invalid, but don’t care how it is invalid.
Since RSS is based on XML, it must have opening and closing tags that match. If they don’t, a MissingTagError will be raised.
Certain attributes are required on specific tags in an RSS feed. If a feed is missing one of these attributes, a MissingAttributeError is raised.
RSS does not allow for free-form tag names, so if an RSS feed contains a tag that we don’t know about, an UnknownTagError is raised.
Raised when an unexpected tag is encountered.
Attributes are in key-value form, and if there’s no value provided for an attribute, a NotAvailableValueError will be raised.
Raised when an unknown conversion error occurs.
