给定下面的示例文本，我试图生成一个正则表达式，它将选择set private-key和-----END ENCRYPTED PRIVATE KEY-----"之间的三个部分，包括set private-key和-----END ENCRYPTED PRIVATE KEY-----"行。
我有表达式^.*set private-key.*$，它选择了第一个部分，然后我有*^-----END ENCRYPTED PRIVATE KEY-----"$，它当然选择了结束部分。我不知道的是如何将它们组合起来选择整个部分。
我尝试过^.*set private-key.*$[\s\S]*^-----END ENCRYPTED PRIVATE KEY-----"$，但最终选择了它找到的第一个set private-key和最后一个-----END ENCRYPTED PRIVATE KEY-----"之间的所有内容，以及它们之间的所有内容。我想选择每个部分，因此在下面的示例中将选择3个部分。
我一直在网上摆弄一些正则表达式实验室，但似乎无法找到这个难题的解决方案，因此我在这里。
谢谢你。
丹
