A simple DTD-driven HTML parser. The parser reads an HTML file from an InputStream and calls various
methods (which should be overridden in a subclass) when tags and data are encountered.
Unfortunately there are many badly implemented HTML parsers out there, and as a result there are many badly formatted HTML files. This parser attempts to parse most HTML files. This means that the implementation sometimes deviates from the SGML specification in favor of HTML.
The parser treats \r and \r\n as \n. Newlines after starttags and before end tags are ignored just as specified in the SGML/HTML specification.
The html spec does not specify how spaces are to be coalesced very well. Specifically, the following scenarios are not discussed (note that a space should be used here, but I am using   to force the space to be displayed):
'<b>blah <i> <strike> foo' which can be treated as: '<b>blah <i><strike>foo'
as well as: '<p><a href="xx"> <em>Using</em></a></p>' which appears to be treated as: '<p><a href="xx"><em>Using</em></a></p>'
If strict is false, when a tag that breaks flow, ( TagElement.breaksFlows) or trailing whitespace is encountered, all whitespace will be ignored until a non whitespace character is encountered. This appears to give behavior closer to the popular browsers. @see DTD @see TagElement @see SimpleAttributeSet @author Arthur van Hoff @author Sunita Mani
