我有一个带有主案例和嵌套案例的 ascii 纯文本文件输入文件，如下所示：我想比较以'$'开头的实例之间的细节和@ExtendedAttr = nvp_add 函数在下面的输入文件中，每个案例在 switch($specific-陷阱），但是当我在 python 脚本部分下运行脚本时，所有嵌套的情况也会被打印出来，我不希望嵌套的情况在这里被打印出来，并且脚本只考虑 switch($specific-case) 下的情况。我该怎么做这个帮助！：

Below is the code which I use suggested by Vaibhav Aggarwal one of the member in 
this stakeoverflow.

这将过滤掉所有嵌套的开关。这仅适用于您的输入文件。
