Class XMLException

public class XMLException extends RuntimeException

The generic superclass for most runtime exceptions thrown in nu.xom. The general principle followed is that anything that can normally be detected by testing such as using spaces in an element name is a runtime exception. Exceptions that depend on environmental conditions, such as might occur when parsing an external file, are checked exceptions, because these depend on variable input, and thus all problems may not be detected during testing.
