looking for a script to convert from xml file format to xls file format
incoming file in xml should be converted to xls file
Microsoft Excel is format is complex to the point of obscure and not suitable for any form of conversion with unix Shell script. Similarly xml is a complex format which requires processing in software designed for the task.
May I suggest that you seek out specialist software to convert xml to xls on a Microsoft platform to suite your detailed specification. There is no general solution to such a question because many xml file layouts will not map to any xls file format.
How about converting xml to csv and get excel to open or import csv directly. If this is acceptable, pls post sample xml file
Excel can open XML files quite well.
