Xml 当存在两个几乎相等的元素时，如何指定XPath？

请参阅下面从WSO2服务器的XML文件中提取的代码片段

    <Server port="8005" shutdown="SHUTDOWN">

    <Service className="org.wso2.carbon.tomcat.ext.service.ExtendedStandardService" name="Catalina">

我计划将具有

端口

属性值的

连接器

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正确吗

xpath:“服务器/服务/连接器[@port=\“9763\”]/maxThreads”

（注意：存在另一个具有相同属性的

连接器
元素）
尝试下面的xpath

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

或

如果另一个
连接器
元素的
端口
属性等于
9763
，您将如何选择？
 "//Connector[@port=\"9763\"]/@maxThreads"
