Hi there, Not sure if this can be done but I would sure like to see if someone knows how to do this: Old text: <book1> <author>ABC</author> <author>DEF</author> <author>GHI</author> </book1> <book2> ... ... etc. Is there a way to use a macro that can change the author tags to: <author1>ABC</author1>...
