我计划将具有Connector属性值的port元素的 maxThreads 属性值更改为9763。如何为上述属性指定提取XPath值？下面的XPath是否正确？

xpath: "Server/Service/Connector[@port=\"9763\"]/maxThreads"

（注意：存在另一个具有某些相同属性的Connector元素）

Answer 1

尝试下面的xpath。

'/Server/Service//Connector[@port="9763"]/@maxThreads'

OR

 "//Connector[@port=\"9763\"]/@maxThreads"

当存在两个几乎相等的元素时，如何指定XPath？
