How it works

  • Schema definitions

  • Processing instructions

  • XML nodes not included in the list

For example, if you create a list from SimpleOrder.xml containing only names and totals, only those elements are saved when you export the list as XML:

In the preceding XML, the original address and order information is omitted because it wasn’t included in the list. From Excel’s point of view, the data doesn’t exist if it doesn’t reside on a worksheet somewhere.

What this means

The limitations that come with XML maps imply a set of ...
