XPaths and <??>

I have a WIX file that I need to modify using MSBuild. It starts like this:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:iis="http://schemas.microsoft.com/wix/IIsExtension">

  <?--... Removed Params ...-->

  <?define ProductVersion = "1.0.1"?>

  <?--... Removed Params ...-->

  <Product Id='$(var.ProductCode)'
    UpgradeCode='$(var.UpgradeCode)'
    Name='$(var.AppName)' Language="1033" Version='$(var.ProductVersion)'
    Manufacturer='$(var.Manufacturer)'>
    <Package Id='$(var.PackageCode)' InstallerVersion="200" 
    Compressed="yes" />

  <?--... Rest of the WIX XML file ...-->

My problem is I don't know what the XPath will be for <?define ProductVersion = "1.0.1"?>

. Is there a way to reference this via XPath so I can use the SDC SetValue MSBuild task to change it? It's not a node (I think), so I'm not sure how to reference it.

It looks like it /Wix/processing-instruction('define')

might work for XPath (whether MSBuild recognizes it, I don't know).



By replacing this in SketchPath , I was able to click on it and test various XPaths to see what would select this item.

Another approach would be to define the parameter via the command line for the candlestick:



candle -dProductVersion=1.0.1

// statement-processing ('define')

<?define>

is a node processing instruction, so you should be able to refer to it using an XPath expression like

//processing-instruction('define')
