[REBOL] Re: html to text and parsing 2 strings

Hi Ian,
There are different ways to go about attacking the problem. Depends what
your aim is.
Here is one idea - does not use the parse function though.
foreach element load/markup http://www.rebol.com [
if string? element [print element]
]
If you are after specific part of a web page you can use the parse function.
parse/all read http://www.rebol.com [
thru "<title>" copy text to </title>
(print text)
]
If you are planning on a general tool then you have more complexity to deal
with. A web page is a structured
document - cells are part of tables for example. But when you have just read
the web page into a string that structure
does not exist - the page is just a sequence of characters/values. So to do
a truly general tool is difficult because you
end up having to program something that understands the structure of web
pages. Adding to this not all web pages
follow the rules...
