我想通过命令行更新xml文件中的值。 我是xmlstartlet的新手，我尝试使用以下命令，但它不能正常工作
xml ed -u "/web-app/welcome-file-list/welcome-file" -v 'Login.jsp' web.xml
在followig XML文件中，我想在欢迎文件节点上将值更新为login.jsp。
这是我的web.xml文件

答案 0 :(得分：2)
它不起作用，因为您的XML位于默认命名空间http://java.sun.com/xml/ns/javaee。
您需要将命名空间绑定到前缀并在xpath中使用它。
示例...
xml ed -N x="http://java.sun.com/xml/ns/javaee" -u "/x:web-app/x:welcome-file-list/x:welcome-file" -v 'Login.jsp' web.xml
