[wix-users] Help with reading XML file properties...

[Lewis Henderson]

Hi Everyone,

I've got an issue reading the contents of an XML configuration file.  For modification installs, I need to read a series of settings from the installed configuration file and assign them to me installer's properties, setting the new "defaults".  I can do this with the Xml_SelectNodeAttributeValue function of the msiext xmltools.dll as shown below, but it's rather cumbersome.  Does anyone have a better method?  Any help is appreciated.
