Answer 1

<node>
<![CDATA[
a&b
]]>
</node>

Answer 2

自己写个通用方法：public static String encode(String text) {
        char c;
        StringBuffer n = new StringBuffer();
        for (int i = 0; i < text.length(); i++) {
            c = text.charAt(i);
            switch (c) {
                case '&':
                    {
                        n.append("&amp;");
                        break;
                    }
                case '<':
                    {
                        n.append("&lt;");
                        break;
                    }
                case '>':
                    {
                        n.append("&gt;");
                        break;
                    }
                case '"':
                    {
                        n.append("&quot;");
                        break;
                    }
                case '\'':
                    {
                        n.append("&apos;");
                        break;
                    }
                default :
                    {
                        n.append(c);
                        break;
                    }
            }
        }
        return new String(n);
    }
