To import nested XML elements (such as additional images), you must enter the field mapping in the following way: 

• Enter each nested XML child our system will traverse, separated by a period.
• For repeating, same-named elements (such as ImageURL), you must put a number at the end for each one.

Example: 

XML looks like this:

<AdditionalImages>
  <ImageURL>ImagefileA.jpg</ImageURL>

</AdditionalImages>
