匹配子节点内容的 xdt 变换定位器 [英] xdt transform locator that matches subnode content

问题描述

我在 web.config 中有以下节点:

<预><代码><配置>...<调度><代理><param desc="database">core</param><代理><param desc="database">master</param></调度>...</配置>

我想删除整个 节点以及带有主内容的子参数节点.或多或少我的 xdt 变换节点看起来像:

<预><代码><配置>...<调度><代理xdt:Transform="删除"xdt:Locator="XPath(./param[@desc='database']/??????)"/></调度>...</配置>

如您所见，我不知道如何与节点内容字符串匹配.我需要在这里添加什么?

环境注意事项:Windows 7 - Visual Studio 2010 SP1

解决方案

将 text() 的额外测试添加到定位器中.匹配 节点:

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

要匹配 节点，您需要将 param 移动到 XPath 匹配的谓词中:

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

i have the following node in web.config:

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

i want to remove the whole <agent> node with the child param node with master content. more or less my xdt transform node looks like:

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

as you see, i have no idea how to match with the node content string. What do i need to add in here?

environment notes: windows 7 - visual studio 2010 SP1

解决方案

Add an extra test for text() into the locator. To match the <param> node:

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

EDIT: To match the <agent> node you need to move param into the predicate that XPath is matching:

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