我有一个ascii纯文本文件输入文件，其中包含主大小写和嵌套大小写，如下所示：我想比较下面输入文件中以"$"开头的细节和@ExtendedAttr=nvp_add函数之间的实例，针对开关下的每个案例（$specific trap），但当我在python脚本下运行脚本时，所有嵌套的案例也都会打印出来，我不希望嵌套的案例在这里打印出来，脚本只考虑开关下的案例（$special case）。我该怎么帮你！：

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。这只适用于您的输入文件。
