This is a module to test the html output of your programs in simple test scripts. it can test a scalar (presumably containing html) for the presence (or absence, or a specific number) of tags having (or lacking) specific attributes. unspecified attributes are ignored, and the attribute values can be specified as either scalars (meaning a match succeeds if the strings are identical) or regular expressions (meaning that a match succeeds if the actual attribute value is matched by the given re) or undef (meaning that the attribute must not be present).
