[wix-users] Remove Entire XML Node

[James Buchan]

It looks like you are missing a "VerifyPath" element (It is mandatory for delete actions)
http://wixtoolset.org/documentation/manual/v3/xsd/util/xmlconfig.html

Here's a snippet of something I have been using

        <util:XmlConfig
                      Id="RSWebConfigConfigSectionUninstall"
                      File="[INSTALLLOCATION]web.config"
                      Action="delete"
                      Node="element"
                      VerifyPath="//configuration/configSections"
                      ElementPath="//configuration"
                      On="uninstall"
                      Sequence="1" />

You don't need to delete the individual child nodes, just aim for the parent.

Subject: [wix-users] Remove Entire XML Node

I have the following XML:

<configuration>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="ScriptModule"/>
      <add name="ScriptModule" preCondition="managedHandler"
type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    </modules>
      <validation validateIntegratedModeConfiguration="false"/>
    <handlers>
      <remove name="WebServiceHandlerFactory-Integrated"/>
      <remove name="ScriptHandlerFactory"/>
      <remove name="ScriptHandlerFactoryAppServices"/>
      <remove name="ScriptResource"/>
      <add name="ScriptHandlerFactory" verb="*" path="*.asmx"
preCondition="integratedMode"
type="System.Web.Script.Services.ScriptHandlerFactory,
System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      <add name="ScriptHandlerFactoryAppServices" verb="*"
path="*_AppService.axd" preCondition="integratedMode"
type="System.Web.Script.Services.ScriptHandlerFactory,
System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      <add name="ScriptResource" verb="GET,HEAD" path="ScriptResource.axd"
preCondition="integratedMode"
type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      <add name="svc-Integrated" verb="*" path="*.svc"
preCondition="integratedMode"
type="System.ServiceModel.Activation.HttpHandler"/>
    </handlers>
    <staticContent>
      <mimeMap fileExtension=".svc" mimeType="application/octet-stream"/>
    </staticContent>
  </system.webServer>
</configuration>

I have a condition that when applicable I would like to remove the node <staticContent> and its child node <mimeMap>

I have tried:

      <util:XmlConfig Id="UpdateMimeMap"
                      Action="delete"
                      On="install"
                      File="[#WebConfig]"

ElementPath="/configuration/system.webServer/staticContent"
                      Node="element"
                      PreserveModifiedDate='yes'
                      Sequence="3">
       </util:XmlConfig>

But this errors out during install with the message:

ExecXmlConfig:  Error 0x80070057: failed to remove created child element CustomAction ExecXmlConfig returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)

Is there a way I can delete the node and child node or do I have to delete the child first, then the parent node?  Or is my delete call incorrect somehow?
