Parse CSS out from <style> elements

Can someone tell me an efficient method of retrieving the CSS between tags on a page of markup in .NET?

Please keep in mind that it is possible...

A better way of getting a data table with various column types into string array

This should be an easy one, looks like I got myself too confused. I get a table from a database, data ranges from varchar to int to Null values. Cheap and dirty way of converting this into a tab-delimited file that I already have is this (shrunken to preserve space, ugliness is kept on par with original): da.Fill(dt) ' da - DataAdapter...

can/should iCal property parametrs be escaped?

specifically, the CN (common name) parameter, e.g. ORGANIZER;CN=John Doe,Eng:mailto:[email protected] The RFC is vague on this, IMHO. It is very clear about property values of type TEXT, but for this parameter it just says "The parameter value is text". Anyways, the escaping specified for TEXT type doesn't seem complete for parameter val...
