我有一个Charles代理记录的xml，我试图通过使用XPath从中查找和提取几个值，但不确定是否在不对xpath进行硬编码的情况下提取它们。下面是单个事务的xml

基本上，我想解析并获取会话中的事务数量，每个事务中的用户代理及其值。我试过PROCESS1 = $（xmllint --xpath'string（/ charles-session / transaction [1] / request / headers / header [1]）'$ XML_FILE）] >>但是，如果不对header []进行硬编码，则无法在每个事务中获取两者。有什么建议吗？

您可以使用它来对用户代理标头进行分组和计数：
