Well, here's a prelim version. I'll have a better version after I see Dave's example. Then we can get in feature/syntax sync. Don't use this version, its not feature complete, and will probably get angry about syntax... A better/real version is forthcoming.

Dave: how much of the scripting news header do I need to implement to stick to the spec?

Here's the input file: -- Hello this is a text document Hello Do you like text documents?

hello this is another text document script stuff --

Here's the output:

-- $ perl parse.pl input.txt Hello this is a text document Do you like text documents? http://www.cnn.com<;/URL> Hello hello this is another text document stuff http://www.scripting.com<;/URL> script --

And here's the source so far...

-- use HTML::Parser;
