I'm not an expert with XmlConfig yet but my understanding is that VerifyPath is
used to tell if the element/attribute is actually present. With VerifyPath
specified the CustomAction can tell during repair and during uninstall if the
element/attribute needs to be fixed/removed. VerifyPath is what was missing
from the old XmlFile implementation that couldn't handle all repair and
uninstall scenarios well.
I think you'll get the uninstall to work if you provide the VerifyPath.

Subject: [WiX-users] Removing nodes with XmlConfig
I've been trying to use the XmlConfig node in WiX v3.0. What I'm trying to do
is to append a new "add"-node under
/configuration/system.data/DbProviderFactories (in machine.config) that should
be removed on uninstall. I think I've figured out how to add it properly, but I
still don't understand how to remove it!
The installation script looks something like this:
<util:XmlConfig Id="Machine_Config_Xml_Root"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\Machine.Config"
Action="create" On="install"
ElementPath="//configuration/system.data/DbProviderFactories"
Name="add"
Node="element" Sequence="1">
</util:XmlConfig>
<util:XmlConfig Id="Machine_Config_Xml_2"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\Machine.Config"
ElementPath="Machine_Config_Xml_Root"
Name="invariant"
Value="MTNE.Framework.Data.CslClient" Sequence="2">
</util:XmlConfig>
(which creates a node looking like this: <add invariant="
MTNE.Framework.Data.CslClient"/>)
But how do I remove it? I've tried this:
<util:XmlConfig Id="Machine_Config_Xml_Uninstall_1"
File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\Machine.Config"
Action="delete" On="uninstall"
ElementPath="//configuration/system.data/DbProviderFactories/[EMAIL
PROTECTED]'MTNE.Framework.Data.CslClient'[\]]"
Sequence="1">
</util:XmlConfig>
but that doesn't seem to do anything at all...
Finally, an other (related?) question.. What is the VerifyPath attribute used
for?
Best Regards,
