3.	Click the expense-report entry, hit the * key on the numeric keypad to view all the items; resize the component if necessary.

4.	Click the Insert XML Schema/File icon.

Make sure that the "Auto connect child items" icon is deactivated, before you create the following mappings.

Create the following mappings between the two components:

•	Expense-report to Company

•	Person to Employee

•	Last to Name

•	Title to Title

•	Phone to Tel.

•	Email to Email

•	expense-item to expense-item

•	Travel to Travel and

•	Trav-cost to Travel-Cost.

The mapping is shown below.

Please note:

Empty <expense-item/> tags are generated when child items of a mapped parent item, exist in the source file, which have not been mapped to the target schema. In this case, only the travel items of the expense-item parent have been mapped. There are however, two other expense items in the list: one lodging and one meal expense item. Each one of these items generates an empty parent expense-item tag.

To avoid generating empty tags, create a filter such as the one described previously in the tutorial, under Filtering data, or connect the Travel item to the expense-item.
