public class SimpleHtmlToText
extends Object

Converts an HTML document to text by stripping out all formatting tags and doing simple conversions. Tables are converted to use tabs and newlines (though nested tables may not appear correct). Multiple blanks are all removed on each line. Leading and trailing blanks are removed on each line. Multiple line breaks are removed. <HR> tags are printed as simple dividers (=============). Common HTML codes are converted to ASCII equivalents (&, ©, <, and >).
