Another BS patent with tons of prior art.
Ahhh!!! You can't imagine the kind of sh&^%&^t you find in patanets:
"A method of navigating the Internet, comprising: displaying on-line content accessed via the Internet, the on-line content reformatted from a webpage in a hypertext markup language (HTML) format into an extensible markup language (XML) format to generate a sister site, the sister site including a portion or a whole of content of the web page reformatted to be displayed and navigable through a simplified navigation interface"
From unix man page at wikipedia:
"The default format of the man pages is troff, with either the macro package man (appearance oriented) or on some systems mdoc (semantic oriented). This makes it possible to typeset a man page to PostScript, PDF and various other formats for viewing or printing."
So any viewer that read one type of markup language and presents result in another type with additional links (or not) is a prior art.
Lynx does it? Linux info viewer? I think so...
