I would try three things:
1) Your ElementPath has a double slash at the beginning. I believe this is
incorrect. We use XmlFile extensively. As an example, here's what one of our
nodes looks like:
<util:XmlFile Id="Local_ErrorDir_nostart"
Action="setValue"
ElementPath="/configuration/appSettings/[EMAIL PROTECTED]'ErrorDir'[\]]/@value"
File="[INSTALLDIR]TransDetailImporterService\TransDetailImportService.exe.config"
Value="[[TARGET_ENVIRONMENT].ERROR_DIR]" />
The file snippet this is editing looks like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="ErrorDir" value="\\Encrypt\failed"/>
</appSettings>
</configuration>
2) Check the syntax of the ElementPath from above against yours. You need
the full path and parameter. The syntax is pretty precise in what it will
accept.
3) It's also possible that your variable (I may have the wrong terminology
here) needs to be public, in other words ALL_CAPS. (not likely though, but it
works for us.)
When all else fails the output log from msiexec usually gives a good indication
of what's going wrong with XmlFile call:
Msiexec /I foo.msi /l* out.txt
Lastly, I have no idea where I stole this script from, but I found a JavaScript
file online that can validate your ElementPath and point you to where any typos
are. I use this thing almost every time I have to edit a new xml file with Wix:
------------------ begin code validate_xml_path.js
if (2 > WScript.Arguments.length)
{
WScript.Echo("Must specify both the file and the XSL Path to query.");
WScript.Quit(1);
}
WScript.Echo("Opening File: " + WScript.Arguments(0));
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
xmlDoc.async = false;
xmlDoc.load(WScript.Arguments(0));
if (0 != xmlDoc.parseError.errorCode)
{
var myErr = xmlDoc.parseError;
WScript.Echo("You have error " + myErr.reason);
}
else
{
WScript.Echo("Query: " + WScript.Arguments(1));
WScript.Echo();
// xmlDoc.setProperty("SelectionLanguage", "XPath");
currNode = xmlDoc.selectSingleNode(WScript.Arguments(1));
if (null == currNode)
{
WScript.Echo("Nothing found.");
}
else
{
WScript.Echo(currNode.text);
}
}
------------------ end code

Subject: [WiX-users] Property replacement issue with WixUIExtension andXmlFile
I'm having a problem with value replacement in a deployed XML file.
I have a property defined ('DataValueProperty') and I allow the user to modify
it in a dialog in the UI. The next dialog shows the successfully modified
value. But when I go to write the value via XmlFile, the deployed XML file
does not get updated.
What happens is the XmlFile custom action updates the xml file with the old
property value. The new property value set by the Edit control is being
ignored.
I am using version 3.0.4014.0 and I have searched the bug database but have not
found anything relevant to what I am seeing.
Here is the property I'm modifying:
<Property Id="DataValueProperty" Value="Default WiX value" />
Here is the component code:
<Component Id="data" Guid="C685777C-5FED-4593-9B9D-9EED1DDECF8E">
<File Id="data" Source="data.xml" />
<util:XmlFile Id="modifyData" Action="setValue"
File="[INSTALLLOCATION]data.xml"
ElementPath="//dataFile/data"
Name="value"
Value="[DataValueProperty]"/>
</Component>
Here is the UI code, I am adding a custom dialog to the WixUIExtension UI:
<Dialog Id="CustomDlg" Width="370" Height="270" Title="[ProductName] [Setup]"
NoMinimize="yes">
<Control Id="PropertyL" Type="Text" X="45" Y="140" Width="200"
Height="10" TabSkip="no" Text="Change DataValueProperty:" />
<Control Id="PropertyText" Type="Edit" X="45" Y="155" Width="220"
Height="15" Property="DataValueProperty" />
<Control Id="Back" Type="PushButton" X="180" Y="243" Width="56"
Height="17" Text="&Back"></Control>
<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56"
Height="17" Default="yes" Text="&Next">
</Control>
<Control Id="Cancel" Type="PushButton" X="304" Y="243" Width="56"
Height="17" Cancel="yes" Text="Cancel">
<Publish Event="SpawnDialog" Value="CancelDlg">1</Publish>
</Control>
<Control Id="BannerBitmap" Type="Bitmap" X="0" Y="0" Width="370"
Height="44" TabSkip="no" Text="WixUI_Bmp_Banner" />
<Control Id="Description" Type="Text" X="25" Y="23" Width="280"
Height="15" Transparent="yes" NoPrefix="yes">
<Text>Please change value for DataValueProperty</Text>
</Control>
<Control Id="BottomLine" Type="Line" X="0" Y="234" Width="370"
Height="0" />
<Control Id="Title" Type="Text" X="15" Y="6" Width="200" Height="15"
Transparent="yes" NoPrefix="yes">
<Text>{\WixUI_Font_Title}Change property</Text>
</Control>
<Control Id="BannerLine" Type="Line" X="0" Y="44" Width="370"
Height="0"/>
</Dialog>
I can send an example solution if anyone wants to take a look.
Are WixUIExtension and WixUtilExtension compatiable to work in this way?
