[WiX-users] XmlConfig and uninstall

I knew that would happen. Solved it just after posting...

It looks like for an uninstall action, the @ElementPath points to the
parent node, while the @VerifyPath is relative to the @ElementPath.

So this works:

<util:XmlConfig Id="XmlRemoveSectionDeclaration"
File="[DirWebInterfaces]web.config" Sequence="1" Action="delete"
On="uninstall" Node="element"
ElementPath="/configuration/configSections"
VerifyPath="section[\[]@name='newSection'[\]]"/>

Cheers,

Andre

Hi all,

Has anyone successfully used util:XmlConfig to modify an XML file on
uninstall?

Adding nodes is working, but removing them on uninstall is still beyond
me. Even with the VerifyPath attribute set, I'm still having no joy.

The below component successfully adds a <section> tag to a web.config,
but leaves it behind on uninstall.

<Component Id="XmlAddSection"
Guid="EB9B4575-467C-4BFB-ACA7-7C3E472A610F" KeyPath="yes">

<CreateFolder/>

<util:XmlConfig Id="XmlAddSectionDeclaration"
File="[DirWebInterfaces]web.config" Sequence="1" Action="create"
On="install" ElementPath="/configuration/configSections" Node="element"
Name="section"
VerifyPath="/configuration/configSections/section[\[]@name='newSection'[
\]]" />

<util:XmlConfig
Id="XmlAddSectionDeclarationName" File="[DirWebInterfaces]web.config"
Sequence="2" ElementPath="XmlAddSectionDeclaration" Name="name"
Value="newSection" >

<util:XmlConfig
Id="XmlAddSectionDeclarationType" File="[DirWebInterfaces]web.config"
Sequence="3" ElementPath="XmlAddSectionDeclaration" Name="type"
Value="blah" />

</util:XmlConfig>



<util:XmlConfig Id="XmlRemoveSectionDeclaration"
File="[DirWebInterfaces]web.config" Sequence="1" Action="delete"
On="uninstall" Node="element"
ElementPath="/configuration/configSections/section[\[]@name='newSection'
[\]]"
VerifyPath="/configuration/configSections/section[\[]@name='newSection'
[\]]"/>

</Component>

In the uninstall log, I see this:

ExecXmlConfig: Error 0x80070057: failed to remove created child element

That HR is something to do with an invalid character I believe?

Thanks,

Andre
