与子节点内容匹配的xdt转换定位器

Question

我在web.config中有以下节点:

<configuration>
...
<scheduling>
 <agent>
  <param desc="database">core</param>
 </agent>
 <agent>
  <param desc="database">master</param>
 </agent>
</scheduling>
...
</configuration>

我想删除<agent>具有主内容的子param节点的整个节点.或多或少我的xdt转换节点看起来像:

<configuration>
...
<scheduling>
  <agent
         xdt:Transform="Remove"
         xdt:Locator="XPath(./param[@desc='database']/??????)" />
</scheduling>
...
</configuration>

如你所见,我不知道如何匹配节点内容字符串.我需要在这里添加什么？

Answer 1

text()在定位器中添加额外的测试.要匹配<param>节点:

xdt:Locator="XPath(./param[@desc='database' and text()='master'])">

编辑:要匹配<agent>您需要移动param到XPath匹配的谓词的节点:

xdt:Locator="Condition(param/@desc='database' and param/text()='master')">
