Recipe 18.1 Import XML Structured as Elements

18.1.1 Problem

You need to import simple XML data into a new

18.1.2 Solution

You can import XML into a new table from the File menu when the
Tables category is selected in the Objects pane by following these

  1. Open

    18-01.MDB .

  2. Choose File Get External Data Import to bring
    up the Import dialog box.

  3. In the Files of type drop-down list at the bottom of the dialog box,
    select XML (*.xml, *.xsd).

  4. In the File name dialog box, navigate to the XML file you want to
    import, and click Import, which will load the XML Import dialog box.
    The samples include an XML file named 18-01.XML that you can use.

  5. Expand the plus sign (+) to show the structure of the XML file and
    click the Options button to expand the dialog box, as shown in Figure 18-2.

  1. The Options button shown in Figure 18-2 enables you
    to specify how you'd like the XML imported. If you
    choose Structure and Data as shown here, a new table will be created.
    Click OK twice to confirm the import.

A new table named Car has been created.

18.1.3 Discussion

When importing an XML file that has the structure Access expects,
containing a hierarchical set of nested elements, the table name is
derived from the first element after the root, in this case
Car. The Make, Model and Price elements become
columns in the table. The source XML file looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
<dataroot xmlns:od="urn:schemas-microsoft-com:officedata">
<Make>Mini Cooper</Make>

When you open the Car table in Datasheet view, it looks like Figure 18-3, with the data organized by column (element),
with each row representing a single Car element in the XML file.

If you import the same file a second time, choosing the same options,
then a second table named Car1 will be created.
Rows will not be appended to the first Car table unless you
explicitly select that option.
