Using xmlstarlet:
使用 xmlstarlet：
xmlstarlet val -e file.xml
xmlstarlet ed -u "//settings/setting/@name" -v 'local directory2' file.xml
xmlstarlet ed -u "//settings[1]/setting/@name" -v 'local directory2' file.xml
# edit file inplace
xmlstarlet ed -L -u "//settings/setting/@name" -v 'local directory2' file.xml

Depending on what you want to do, you may want to use some XML-specific tooling (to handle character encodings, to maintain XML well-formedness etc.). You can use the normal line-oriented tools, but unless you're careful (or doing something trivial) you can easily create non-compliant XML.
根据您想要做什么，您可能想要使用一些特定于 XML 的工具（处理字符编码、维护 XML 格式良好等）。您可以使用普通的面向行的工具，但除非您小心（或做一些无关紧要的事情），否则您很容易创建不兼容的 XML。
I use the XMLStarletcommand line set. It's a set of command line utilities for specifically parsing/manipulating XML.
我使用XMLStarlet命令行集。它是一组专门用于解析/操作 XML 的命令行实用程序。

Most people would probably use sed to do line editing from a bash script. If you actually care about parsing the XML, then use something like Perl which has a ready XML parser.
大多数人可能会使用 sed 从 bash 脚本进行行编辑。如果你真的关心解析 XML，那么使用像 Perl 这样的东西，它有一个现成的 XML 解析器。

An ugly/unsafe but sometimes the easiest is to call sed/perl/awk from bash
丑陋/不安全但有时最简单的是从 bash 调用 sed/perl/awk
