XMLStarlet 删除父节点 [英] XMLStarlet delete parent node

问题描述

我是 XMLStarlet 的新手，我想知道是否有可能删除一个父节点，该父节点在其标签中具有一个具有特定值的子节点.

I'm new using XMLStarlet and I'm wondering whether there is the possibility to remove a parent node that has a child with a specific value inside his tag.

在我的示例中，我想删除节点"；在子节点内部具有"具有特定值SecondTab":

In my example, I want to remove the node "<tabVisibilities>" that has inside a child node "<tab>" with the specfic value "SecondTab":

开始 XML:

<?xml version="1.0" encoding="UTF-8"?>
<Profile xmlns="http://soap.sforce.com/2006/04/metadata">
    <tabVisibilities>
        <tab>FirstTab</tab>
        <visibility>DefaultOn</visibility>
    </tabVisibilities>
    <tabVisibilities>
        <tab>SecondTab</tab>
        <visibility>DefaultOn</visibility>
    </tabVisibilities>
    <tabVisibilities>
        <tab>ThirdTab</tab>
        <visibility>DefaultOff</visibility>
    </tabVisibilities>
</Profile>

预期的 XML:

<?xml version="1.0" encoding="UTF-8"?>
<Profile xmlns="http://soap.sforce.com/2006/04/metadata">
    <tabVisibilities>
        <tab>FirstTab</tab>
        <visibility>DefaultOn</visibility>
    </tabVisibilities>
    <tabVisibilities>
        <tab>ThirdTab</tab>
        <visibility>DefaultOff</visibility>
    </tabVisibilities>
</Profile>

非常感谢，大卫.

推荐答案

您的文件使用命名空间.

Your file uses namespaces.

xmlstarlet edit -N ns='http://soap.sforce.com/2006/04/metadata' --delete "//ns:tabVisibilities[ns:tab[contains(text(),'SecondTab')]]" file.xml

输出:

<?xml version="1.0" encoding="UTF-8"?>
<Profile xmlns="http://soap.sforce.com/2006/04/metadata">
  <tabVisibilities>
    <tab>FirstTab</tab>
    <visibility>DefaultOn</visibility>
  </tabVisibilities>
  <tabVisibilities>
    <tab>ThirdTab</tab>
    <visibility>DefaultOff</visibility>
  </tabVisibilities>
</Profile>
