Hi I don't think this is possible but I have a value that needs to be used in multiple xml Config files for a Sitecore site. The problem is that the client only wants to update the value in one place.
for example if I have a file with a node with a value of
<settingexample name="ExampleGroup"/>
can I replace ExampleGroup
with something that might link it to a settings xml file with the following setting
<setting name="ExampleProject.UserDomain" value="ExampleGroup"/>
That way all the xml nodes will match if I change it in a single place.
