XML File Help / Denomalized Data

Question

Hi,
Some software I work with allows me to import an XML file to create products into a database.  I was given an example XML file and have sucessfully used this and edited it using XML Notepad.  I have two records in the file which I can
import into the database without issue.
If I import the XML map into Excel and then try to add further records or edit what is already there and export out the XML it tell me that XML Maps are not exportable and if I do the verify map for export it tells me I get denormalized data.  As
I'm new to working with this I wonder if anyone can tell from the XML below what the problem is when trying to use it in Excel?
Thank you.
Robin

Not quite familiar with XML, but you can take a look at this:
An XML mapping cannot be exported if the mapped element’s relationship with other elements cannot be preserved. This relationship may not be preserved for the following reasons:
The schema definition of a mapped element is contained within a sequence with the following attributes:
The maxoccurs attribute is not equal to 1.
The sequence has more than one direct child element defined, or has another compositor as a direct child.
Nonrepeating sibling elements with the same repeating parent element are mapped to different XML tables.
Multiple repeating elements are mapped to the same XML table, and the repetition is not defined by an ancestor element.
Child elements from different parents are mapped to the same XML table.
Additionally, the XML mapping cannot be exported if it contains one of the following XML schema constructs:
List of lists    One list of items contains a second list of items.
Denormalized data    An XML table contains an element that has been defined in the schema to occur once (the
maxoccurs attribute is set to 1). When you add such an element to an XML table, Excel fills the table column with multiple instances of the element.
Choice    A mapped element is part of a
<choice> schema construct.
