public class Astro2007aHtmlTableReader
extends Object

A reader that can turn HTML in the form presented in the 2007a Astro Catalogue into sources.

Warning: This reader is not an industrial strength class and was intended for use by those who are not overly concerned with the failure to read the HTML. The main problem with this class is that several exceptions are stifled and do not reach clients of this class.
