xmlstarlet 不更新内容

Question

我在更新以下 xml 文件时遇到问题。

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<config xmlns="http://artifactory.jfrog.org/xsd/2.0.5" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.jfrog.org/xsd/artifactory-v2_0_5.xsd">

        <passwordMaxAge>60</passwordMaxAge>
        <notifyByEmail>true</notifyByEmail>
      </expirationPolicy>
      <resetPolicy>
        <enabled>true</enabled>
        <maxAttemptsPerAddress>3</maxAttemptsPerAddress>
        <timeToBlockInMinutes>60</timeToBlockInMinutes>
      </resetPolicy>
    </passwordSettings>...

我想把下面的值改成5

<maxAttemptsPerAddress>3</maxAttemptsPerAddress>

阅读大量文档后，包括 Whosebug 上的多篇类似于 this

的帖子

并尝试了数十个这样的命令和变体：

xmlstarlet ed --inplace -u '/config/security/passwordSettings/expirationPolicy/resetPolicy/maxAttemptsPerAddress' -v 5 test.xml

xmlstarlet ed --inplace -u /config[@xmlns=*][@xmlns:xsi=*][@xsi:schemaLocation=*]/security/passwordSettings/expirationPolicy/resetPolicy/maxAttemptsPerAddress -v 5 test.xml

xmlstarlet ed --inplace -u /config[@xmlns="http://artifactory.jfrog.org/xsd/2.0.5"][@xmlns:xsi=*][@xsi:schemaLocation=*]/security/passwordSettings/expirationPolicy/resetPolicy/maxAttemptsPerAddress -v 5 test.xml

xmlstarlet 仍然没有更新所需的值：我认为这里的主要问题是多个 xmlns 配置值，但到目前为止我还没有找到解决方案。

Answer 1

您实际上需要使用选项 -N 定义命名空间，并为每个节点显式使用它：

xmlstarlet ed -N a="http://artifactory.jfrog.org/xsd/2.0.5" -u /a:config/a:security/a:passwordSettings/a:resetPolicy/a:maxAttemptsPerAddress -v 5 file.xml

此处命名空间a设置为http://artifactory.jfrog.org/xsd/2.0.5，用于定位要更新的xpath的所有节点。
