Hi Phillip,
Just try using "ElementId" while creatinf attributes of an element. You don't
need to create anther depoyment element, just refer it by using "ElementId".
For Deletion on Un-install, you need to specify "On=Uninstall" attribute to
XMLConfig.
Hope this help
Thanks
Jaspreet Ssingh

Subject: [WiX-users] Creating or Updating an Xml Element
I want to update my machine.config to create the <deployment> element in
system.web if and only if it does not already exist. Then I want to
update the retail attribute to be set to "true" no matter whether or not
the <deployment> element existed before the install began. Here is my
WiX snippet:
<Component Id="MachineConfigUpdates" Guid
="{FA828AD3-4E9B-4f24-921B-93E755A2A487}" KeyPath="yes">
<util:XmlConfig Id="MachineConfigAdd"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.c
onfig" Action="create"
ElementPath="//configuration/system.web"
Name="deployment" Node="element" Sequence="1" On="install" />
<util:XmlConfig Id="MachineConfigKey"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.c
onfig"
ElementPath="MachineConfigAdd" Name="retail"
Value="true" Sequence="2" />
</Component>
The problem is that it creates another <deployment> element every time
the install begins. How can I fix this issue? I also tried adding a
delete at the beginning of this component. Even if this worked it would
not be ideal because it would eliminate any other attributes of the
<deployment> element that may already have been set.
Here is my snippet with the delete:
<Component Id="Mss.MachineConfigUpdates" Guid
="{FA828AD3-4E9B-4f24-921B-93E755A2A487}" KeyPath="yes">
<util:XmlConfig Id="MachineConfigDelete"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.c
onfig" Action="delete"
ElementPath="//configuration/system.web" Name="deployment"
Node="element" Sequence="1" On="install" />
<util:XmlConfig Id="MachineConfigAdd"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.c
onfig" Action="create"
ElementPath="//configuration/system.web"
Name="deployment" Node="element" Sequence="2" On="install" />
<util:XmlConfig Id="MachineConfigKey"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.c
onfig"
ElementPath="MachineConfigAdd" Name="retail"
Value="true" Sequence="3" />
</Component>
In this case, the delete seems to be ignored and I get the same result:
multiple <deployment> elements in my machine config.
Any ideas?
Thanks.
- Phil
