Hi Blair, a useful tool to check your Xpath expression is http://xpathtester.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=3600
I had the same problem but after the correct Syntax it works fine. BR Michael -----Ursprüngliche Nachricht----- Von: Blair [mailto:os...@live.com] Gesendet: Dienstag, 06.

Betreff: Re: [WiX-users] Unable to use Xpath expressions XMLFile uses the msxml3 engine that was released before XPath 1.0 became finalized. As such, you have to set the SelectionLanguage attribute (the obsolete working-draft predecessor to XPath is too different and too limited and is the unfortunate "default"). Here is what I tested: <util:XmlFile Id="AddStuff" Action="createElement" File="[#Config.xml]" ElementPath="/stuffs" Name="stuff" SelectionLanguage="XPath" Sequence="1"/> <util:XmlFile Id="AddStuffName" Action="createElement" File="[#Config.xml]" ElementPath="/stuffs/stuff[\[]last()[\]]" Name="name" SelectionLanguage="XPath" Sequence="2" Value="new stuff"/> -----Original Message----- From: pan.pantzia...@compassmc.com [mailto:pan.pantzia...@compassmc.com] Sent: Tuesday, October 06, 2009 12:44 PM To: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Unable to use Xpath expressions It successfully performs the first action and inserts the new element.

The format of the file is something like this: <stuffs> <stuff> <name>first stuff</name> </stuff> <stuff> <name>more stuff</name> </stuff> </stuffs> I want to add another stuff element to the end of the file and am trying to use XMLFile as follows: <DirectoryRef Id="ConfigXML"> <Component Id="XMLFile" Guid="My-GUID"> <File Id="SettingsXmlFile" Name="config.xml" Source="c:\path\to\xmlfile\config.xml" DiskId="1" Vital="yes" /> <util:XmlFile Id="AddStuff" Action="createElement" ElementPath="/stuffs" Name="stuff" File="c:\path\to\xmlfile\config.xml " Sequence="1"/> <util:XmlFile Id="AddStuffName" Action="createElement" ElementPath="/stuffs/stuff[\[]last()[\]]" Name="name" Value="new stuff" File=" c:\path\to\xmlfile\config.xml " Sequence="2"/> </Component> </DirectoryRef> I've tried escaping and not escaping the Xpath expression to get the last stuff element, which is the last one added, but all I get are errors. I've tried all sorts of kludges to reference the new stuff element but to no avail. This is with the 3.0.5419.0 build of WiX 3.0. I can't get any xpath expression to resolve at all... What am I doing wrong?
