Map XML elements to cells in an XML Map

Locate or create XML schema and XML data files

If another database or application created an XML schema or XML data file, you might already have them available. For example, you might have a line-of-business application that exports data into these XML file formats, a commercial web site or web service that supplies these XML files, or a custom application developed by your IT department that automatically creates these XML files.

If you don’t have the necessary XML files, you can create them by saving the data you want to use as a text file. You can then use both Access and Excel to convert that text file to the XML files you need. Here’s how:

Access

1. Import the text file you want to convert and link it to a new table.

   1. Click File > Open.

   2. In the Open dialog box, select and open the database in which you want to create a new table.

   3. Click External Data > Text File, and follow the instructions for each step, making sure that you link the table to the text file.

      Access creates the new table and displays it in the Navigation Pane.

2. Export the data from the linked table to an XML data file and an XML schema file.

   1. Click External Data > XML File (in the Export group).

   2. In the Export - XML File dialog box, specify the file name and format, and click OK.

3. Exit Access.

Excel

1. Create an XML Map based on the XML schema file you exported from Access.

   If the Multiple Roots dialog box appears, make sure you choose dataroot so you can create an XML table.

2. Create an XML table by mapping the dataroot element. See Map XML elements for more information.

3. Import the XML file you exported from Access.

Use sample XML schema and XML data files

The following sample data has basic XML elements and structures you can use to test XML mapping if you don't have XML files or text files to create the XML files. Here’s how you can save this sample data to files on your computer:

1. Select the sample text of the file you want to copy, and press Ctrl+C.

2. Start Notepad, and press Ctrl+V to paste the sample text.

3. Press Ctrl+S to save the file with the file name and extension of the sample data you copied.

4. Press Ctrl+N in Notepad and repeat step 1-3 to create a file for the second sample text.

5. Exit Notepad.

Sample XML schema (Expenses.xsd)

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="Root">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element minOccurs="0" maxOccurs="1" name="EmployeeInfo">
          <xsd:complexType>
            <xsd:all>
              <xsd:element minOccurs="0" maxOccurs="1" name="Name" />
              <xsd:element minOccurs="0" maxOccurs="1" name="Date" />
              <xsd:element minOccurs="0" maxOccurs="1" name="Code" />

      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

Create an XML Map

You create an XML Map by adding an XML schema to a workbook. The schema can be copied from an XML schema file (.xsd), or Excel can try to infer one from an XML data file (.xml).

1. Click Developer > Source.

   

   If you don't see the Developer tab, see Show the Developer tab.

2. In the XML Source task pane, click XML Maps, and then click Add.

3. In the Look in list, click the drive, folder, or Internet location that contains the file you want to open.

4. Click the file, and then click Open.

   • For an XML schema file, XML will create an XML Map based on the XML schema. If the Multiple Roots dialog box appears, choose one of the root nodes defined in the XML schema file.

   • For an XML data file, Excel will try to infer the XML schema from the XML data, and then creates an XML Map.

5. Click OK.

   The XML Map appears in the XML Source task pane.

Map XML elements

You map XML elements to single-mapped cells and repeating cells in XML tables so you can create a relationship between the cell and the XML data element in the XML schema.

1. Click Developer > Source.

   

   If you don't see the Developer tab, see Show the Developer tab.

2. In the XML Source task pane, select the elements you want to map.

   To select nonadjacent elements, click one element, and then hold down Ctrl and click each element you want to map.

3. To map the elements, do the following:

   1. Right-click the selected elements, and click Map element.

   2. In the Map XML elements dialog box, select a cell and click OK.

      Tip: You can also drag the selected elements to the worksheet location where you want them to appear.

      Each element appears in bold type in the XML Source task pane to indicate the element is mapped.

4. Decide how you want handle labels and column headings:

   • When you drag a nonrepeating XML element onto the worksheet to create a single-mapped cell, a smart tag with three commands is displayed, which you can use to control the placement of the heading or label:

     My Data Already Has a Heading    Click this option to ignore the XML element heading, because the cell already has a heading (to the left of the data or above the data).

     Place XML Heading to the Left    Click this option to use the XML element heading as the cell label (to the left of the data).

     Place XML Heading Above    Click this option to use the XML element heading as the cell heading (above the data).

   • When you drag a repeating XML element onto the worksheet to create repeating cells in an XML table, the XML element names are automatically used as column headings for the table. However, you can change the column headings to any headings that you want by editing the column header cells.

     In the XML Source task pane, you can click Options to further control XML table behavior:

     Automatically Merge Elements When Mapping    When this check box is selected, XML tables are automatically expanded when you drag an element to a cell adjacent to the XML table.

     My Data Has Headings    When this check box is selected, existing data can be used as column headings when you map repeating elements to your worksheet.

     Notes: 

     • If all XML commands are dimmed, and you can't map XML elements to any cells, the workbook might be shared. Click Review > Share Workbook to verify that and to remove it from shared use as needed.

       If you want to map XML elements in a workbook you want to share, map the XML elements to the cells you want, import the XML data, remove all of the XML maps, and then share the workbook.

     • If you can't copy an XML table that contains data to another workbook, the XML table might have an associated XML Map that defines the data structure. This XML Map is stored in the workbook, but when you copy the XML table to a new workbook, the XML Map isn't automatically included. Instead of copying the XML table, Excel creates an Excel table that contains the same data. If you want the new table to be an XML table, do the following:

       1. Add an XML Map to the new workbook by using the .xml or .xsd file you used to create the original XML Map. You should save these files if you want to add XML Maps to other workbooks.

       2. Map the XML elements to the table to make it an XML table.

     • When you map a repeating XML element to a merged cell, Excel unmerges the cell. This is expected behavior, because repeating elements are designed to work with unmerged cells only.

       You can map single, nonrepeating XML elements to a merged cell, but mapping a repeating XML element (or an element that contains a repeating element) to a merged cell isn't allowed. The cell will be unmerged, and the element will be mapped to the cell where the pointer is located.

Show the Developer tab

If you don't see the Developer tab, do the following to display it:

1. Click File > Options.

2. Click the Customize Ribbon category.

3. Under Main Tabs, check the Developer box, and click OK.
