Question

我使用xmlstarlet编辑一些xml配置文件。默认文件如下所示：

<configuration>
  <property>
    <name></name>
    <value></value>
  </property>
  <property>
    <name></name>
    <value></value>
  </property>
</configuration>

我正在添加更多<property>个子节点。像这样：

    sudo xmlstarlet ed -L \
      -s '//configuration' -t elem -n "property" \
      -s '//configuration/property[last()]' -t elem -n "name" -v "test-1" \
      -s '//configuration/property[last()]' -t elem -n "value" -v "00001" \
      -s '//configuration' -t elem -n "property" \
      -s '//configuration/property[last()]' -t elem -n "name" -v "test-2" \
      -s '//configuration/property[last()]' -t elem -n "value" -v "00002" \
      /etc/path/to/file.xml

我在本地测试了这个，使用了XMLStarlet 1.6.1，它运行得非常好，而且我想要它。结果如下：

<configuration>
  <property>
    <name></name>
    <value></value>
  </property>
  <property>
    <name></name>
    <value></value>
  </property>
  <property>
    <name>test-1</name>
    <value>00001</value>
  </property>
  <property>
    <name>test-2</name>
    <value>00002</value>
  </property>
</configuration>

但是，当我把它放在一个shell脚本中，然后尝试在我的远程实例（使用XMLStarlet 1.3.1）上运行它时，它会一直打印出包的帮助文本，就像你只需输入xmlstarlet一样终点站。我不知道是什么导致了这个

xmlstarlet ed -s在这两个版本中都有效;改变了什么，使我的脚本特定于版本？

Answer 1

在XMLStarlet 1.3.1（您在远程系统上），-v的{{1}}参数是必需的。

因此，您需要在添加xmlstarlet ed -s元素时添加-v ''。

XMLStarlet ed -s在1.3.1上给出了使用错误，适用于1.6.1 - 改变了什么？
