使用JAVA对下面的复杂文本进行解析,这是一个菜谱的txt文本文件,下面只列出两道菜谱,其余格式都相同.只要能分别解析出Name,Categories,和下面的配料,存入一个对象中即可。请给出解析步骤的详细代码

大侠们拜托了,之后必定追加最高分.

下面是菜谱的文本格式

Name: Yu xiang rou si
Categories: Pork, Chinese 500 g Pork 10 g sugar
10 g chilly 1 1/2 g salt
15 g oil In large bowl, blend oil and sugars on low until well mixed. Add chilly.
Beat in salt... ----- Name: xi hong shi chao ji dan
Categories: tomato, Chinese 300 g tomato 10 g sugar
5 g oil 2 1/2 g salt Chop tomatoes, blend oil and sugars on low until well mixed.
add some salt... -----
配料部分是不确定的, 比如
2 1/2 c Brown sugar 2 ts Cloves
2 c Sour milk 2 ts Nutmeg
4 c Flour 3 ea Eggs, lg
3/4 c Butter 15 oz Raisins
2 c Jam 1 c Nutmeats
2 ts Baking soda 1 x Figs and dates as desired
这个也应该需要解析至少存在一个数组或者list里 http://zhidao.baidu.com/link?url=eZtAHGCL3EM3OrpBdzKj6LAWnxZSQkG7PzUqZ7BT347wuyuI_VKCv34Mz7j6XsC0CVf17lo4OJ2oYvmV36rvaq
