The Export to XML code template is used to write the contents of a valid data source (or origin) to an external XML file. This code template is actually a wrapper around the built-in class library support for XML parsing.

The following prompts are provided:

| **Data Origin** | Press the** **ellipsis button to select a valid label of a GROUP, FILE, VIEW or QUEUE that holds the XML contents to export to an XML file. Press the "**E**" button to call the Expression Editor. This dialog is used to help you construct syntactically correct expressions to use in the **Data Origin** prompt. |
| **Mapping File** | Press the ellipsis button to select a valid XML mapping file to use during the export process. In Clarion terms, mapping refers to associating an XML tag or schema to a database column name. If you wish to select this file at runtime, check the **Select mapping file at runtime **check box. You may also specify a variable here (Example: //!FilenameVariable//). |
| **Export File** | Press the ellipsis button to select the valid XML source file name to export to. If you wish to select this file at runtime, check the **Select export file at runtime **check box. You may also specify a variable here (Example: //!FilenameVariable//). |
| **Root Tag:** | Enter a hard coded string value, or specify a variable that will identify the root tag name (using the //!variablename// format) to begin the export to. |
| **Row Tag:** | Enter a hard coded string value, or specify a variable that will identify the row tag name (using the //!variablename// format) to begin the export to. |

Root and Row Tags can contain letters, numbers, and other characters. They must not start with a number or punctuation character or with the letters xml (or XML or Xml ..). They cannot contain spaces

| **XML Style** | Select //Tag-based// or //Attribute-based//. This setting controls the XML formatted output style. |
