Description
Reads the XML from a file and convert it to an
XML document object.
Sets the accountNum variable from the
customer entry's accountnum attribute.
Converts the XML document object into a
query object.

name, qty, and unitPrice values for each item.
For each XML item entry in the
mydoc.order.items entry, fills one row of the
query with the item's id attribute and the text in
the name, quantity, and unitprice entries that
the it contains.
If the account number is the same as an
employee ID in the CompanyInfo database
Employee table, the query returns one record.
