Let qmake check whether Info.plist is in XML format

When a user modifies a given Info.plist using a GUI editor, he might save it in binary format, which is perfectly valid in the context of OS X plist format.

qmake however needs Info.plist in text format (XML) in order to perform the sed command to replace the variables @EXECUTABLE@, @ICON@, @TYPEINFO@, @LIBRARY@, and @SHORT_VERSION@.

sed command from my Makefile:

@sed -e "s,@SHORT_VERSION@,1.0,g" -e "s,@FULL_VERSION@,1.0.0,g" -e "s,@TYPEINFO@,????,g" -e "s,@BUNDLEIDENTIFIER@,com.example.product,g" -e "s,@ICON@,myproduct.icns,g" -e "s,@EXECUTABLE@,MyProduct,g" -e "s,@TYPEINFO@,????,g" ../../project/subproject/Info.plist >MyProject.app/Contents/Info.plist

This confuses users.

I'd love to see a check in the Makefile, that ensures that the file is

• in text format
• valid XML
