这个是我用ABAQUS处理得到的INP文件，我想用其中的单元数和节点数做后续分析（只要数字的哦！），该怎么读取呢？
得到的INP文件内容如下（部分数据以省略号代替）：
*Heading
** Job name: 1B Model name: 1
*Preprint, echo=NO, model=NO, history=NO, contact=NO
**
** PARTS
**
*Part, name=PART-1-1

我希望得到的结果是这样的，就是把星号部分的内容和文字去掉：
第一，把单元数7888和节点数35683提取到第一行；
第二，把各个单元的应力值（3个应力/每单元）读出，把各节点的单元号及其对应的节点号(就是每个单元后面对应的20个值)读出来
也就是一得到以下这样的结果
35683,7888
1, 3.60278225, 0., 40.5839424
2, 3.89955282, 0., 40.5839424
