Answer 1

In general, for parsing out data from HTML, you should use a purpose built HTML parser.

Two good options are:

• HTML Agility Pack - uses XPath / LINQ to query the parsed HTML
• CsQuery - uses jQuery like selector syntax to query the parsed HTML

The choice between the two should boil down to which query syntax you (and your team) are more comfortable with.
