java.lang.Object
   javax.swing.text.html.CSSParser

A CSS parser. This works by way of a delegate that implements the CSSParserCallback interface. The delegate is notified of the following events:

Import statement: handleImport
Selectors handleSelector. This is invoked for each string. For example if the Reader contained p, bar , a {}, the delegate would be notified 4 times, for 'p,' 'bar' ',' and 'a'.
When a rule starts, startRule
Properties in the rule via the handleProperty. This is invoked one per property/value key, eg font size: foo;, would cause the delegate to be notified once with a value of 'font size'.
Values in the rule via the handleValue, this is notified for the total value.
When a rule ends, endRule

This will parse much more than CSS 1, and loosely implements the recommendation for Forward-compatible parsing in section 7.1 of the CSS spec found at: http://www.w3.org/TR/REC-CSS1. If an error results in parsing, a RuntimeException will be thrown.

This will preserve case. If the callback wishes to treat certain poritions case insensitively (such as selectors), it should use toLowerCase, or something similar.
