The pattern I follow is to: 1) have a custom action read XPaths from a table and save what it finds in the existing file into properties; 2) re-write the XML file on install/upgrade with the values in those properties;
It is certainly possible to do a source control like merge, but your custom actions are going to have to handle all the edge-cases. -- John Merryweather Cooper Build & Install Engineer -- ESA Jack Henry & Associates, Inc.(r) Shawnee Mission, KS 66227 Office: 913-341-3434 x791011 jocoo...@jackhenry.com www.jackhenry.com -----Original Message----- From: j2associates [mailto:j2associa...@yahoo.com] Sent: Friday, November 1, 2013 2:36 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Saving existing xml file on uninstall and then merging it back in during reinstall Hello all, We have a config file that is installed which can be customized post installation (not sensitive data). How can we save the config file during uninstall so that customizations can be merged into the new install. I was thinking along the following: A. During uninstall copy the config file to the user's Temp folder so if reinstall never happens it is no big deal B. During install, check the user's Temp folder and if the file is present, merge it and delete it Is this feasible, or is there a better way? In either case, can someone point me to some sample code? -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Saving-existing-xml-file-on-uninstall-and-then-merging-it-back-in-during-reinstall-tp7590217.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Android is increasing in popularity, but the open development platform that developers love is also attractive to malware creators.
