xml - WIX 安装程序 : Cannot set more than one appSettings node

Question

我在 wix 安装程序中有以下内容:

<util:XmlFile Id="leID4" File="[INSTALLFOLDER]app.config" Sequence="5"
                      Action="setValue" ElementPath="/configuration/appSettings/add[\[]@key='JobProcessorTimerInterval'[\]]/@value" Value="60000" Permanent="yes" />

<util:XmlFile Id="leID5" File="[INSTALLFOLDER]app.config" Sequence="6"
                      Action="setValue" ElementPath="/configuration/appSettings/add[\[]@key='FromEmail'[\]]/@value" Value="[FROMEMAIL]" Permanent="yes" />

这是我的 app.config 文件:

<configuration>
<appSettings>
    <add key="FromEmail" value="test@hotmail.com" />
    <add key="JobProcessorTimerInterval" value="60000"/>
</appSettings>
</configuration>

当我运行安装程序时，我收到此消息:

我尝试了多种方法，但似乎无法正常工作。谁能看出我哪里出错了？

你能试试下面的吗？ WIX 文档指出:

"setValue - Sets a value in the element specified in the ElementPath. If Name is specified, and attribute with that name is set to the value specified in Value. If Name is not specified, the text value of the element is set. Value is a required attribute if setValue is the action specified."

    <util:XmlFile Id="leID4" 
                        File="[#filename]" 
                        Sequence="5"
                        Action="setValue" 
                        ElementPath="//appSettings/add[\[]@key='JobProcessorTimerInterval'[\]]" 
                        Name="value" 
                        Value="60000" 
                        Permanent="yes" 
                        SelectionLanguage="XPath" />

    <util:XmlFile Id="leID5"
                        File="[#filename]" Sequence="6"
                        Action="setValue" 
                        ElementPath="//appSettings/add[\[]@key='FromEmail'[\]]" 
                        Name="value" 
                        Value="[FROMEMAIL]" 
                        Permanent="yes" 
                        SelectionLanguage="XPath" />

<File Id="filename" Name="xmlfiletest" Source="..\\xmlfile1.xml">
          </File>

filename 是您的 WIX 中 app.config 文件的 FILE 元素的 ID 属性。
