xmlstarlet-更新特定节点上的值

Question

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，但它不起作用

xml ed -u "/web-app/welcome-file-list/welcome-file" -v 'Login.jsp' web.xml

在以下 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

Answer 1

它不起作用，因为您的 XML 在默认命名空间 http://java.sun.com/xml/ns/javaee 中.

您需要将命名空间绑定(bind)到前缀并在 xpath 中使用它。

例子...

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
