您可以使用CSS Parser。这不是完美的，那很简单，但它给你更多...

public Map<String, CSSStyleRule> parseCSS() throws IOException { 
    Map<String, CSSStyleRule> rules = new HashMap<String, CSSStyleRule>(); 

    InputSource inputSource = new InputSource(new FileReader("bootstrap.css")); 
    CSSStyleSheet styleSheet = new CSSOMParser().parseStyleSheet(inputSource, null, null); 

    CSSRuleList ruleList = styleSheet.getCssRules(); 
    for (int i = 0; i < ruleList.getLength(); i++) { 
     CSSRule rule = ruleList.item(i); 
     if (rule.getType() == CSSRule.STYLE_RULE) { 
      CSSStyleRule styleRule = (CSSStyleRule) rule; 
      rules.put(styleRule.getSelectorText(), styleRule); 
     } 
    } 

    return rules; 
}
