Recipe 18.5 Exporting Selected Columns to an HTML Table

18.5.1 Problem

You'd like to export
data from a table as XML and display it in an HTML table. However, you only want to
display selected columns from the table, not the entire table.

18.5.2 Solution

If you wish to export data using only selected columns, you can do so
with a query, but you can also accomplish this by using an XSLT transform. Using a transform has
the added benefit of allowing you to format the data as HTML. Follow
these steps to export only the Make and Model data from the Car table
and to format the data as an HTML table:

  1. Select the Car table in the database window, right-click and select
    Export, and choose XML in the Save as type drop-down list at the
    bottom of the dialog box.

  2. Type a name for the XML file ending with an htm suffix and click the
    Export button. This example assumes that the output file is named

  3. Click the More Options button to load the Export XML dialog box shown
    in Figure 18-15. You can change the output file name
    here if you didn't change it in the previous dialog

Figure 18-15. Selecting the output location and filename

  1. Click the Transforms button. If the transform
    doesn't show up in the list, click the Add button to
    browse to it. This example uses a transform named 18-05.xsl. Click OK
    and OK again. Access will create a Car and a Car.xsd file in the
    destination directory.

18.5.3 Discussion

The 18-05.xsl file used to transform the data contains two templates.
The dataroot template contains code for creating an HTML document
with an HTML table. The Car template creates the rows in the HTML
table and cells containing only the Make and Model data. This
transform works against a hidden XML document that is created from
all the data in the table:

<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsl="" version="1.0" >
<xsl:output method="html" version="4.0" indent="yes" />
<xsl:template match="dataroot">
<xsl:apply-templates select="Car" />
<xsl:template match="Car">
<td><xsl:value-of select="Make" /></td>
<td><xsl:value-of select="Model" /></td>

When you view Car in a browser, you can see that the data is
displayed in an HTML table, as shown in Figure 18-16.

Choose View > Source from the menu and you'll see
the following HTML:

<td>Mini Cooper</td>

This example is very simple and creates just a bare-bones table. You
can modify the HTML sections of the XSLT to specify colors, borders,
fonts, and so on to create whatever custom formatting you
