MySQL to XML: How to transfer data from MySQL to XML File
Step
1. Create a new job, and open the [Design Job] interface.
2. Create a new MySQL dataset as target in [Design Job] interface, and open the property dialog of MySQL dataset, set MySQL connection parameters in [Database] sheet, then click [Import field definition] button in [Fields] sheet to import field definition information.
Following is the detailed parameters of MySQL should be setted.
Property name
Description
Connection Type
Set the property by one of the following connection configurations:
Direct connection: MySQL client does not need installed on client side.
Standard connection: MySQL client need installed.

Field
List the definition information of the field that has the above format.
Before reading source data, you must define fieldĄ¯s information. About how to get field information.
3. Create a new Local file dataset as target in [Design Job] interface,
and open the property dialog of Local file dataset, set table type as "XML file" in [General] sheet, and set other parameter,
then click [Import field definition] button in [Fields] sheet to import field definition information.
Following is the most important parameters of Local file should be setted.
Property name
Description

xmlIE:XML-file which all rows are aligned using spaces, so you can view this file in any text editor in "tree"-mode. This mode is optimized for viewing in MS Internet Explorer browser.
xmlIECompact: similar to xmlIE but total number of spaces is limited.
xmlClientDataset:XML-file which is compatible with TClientDataset component in Delphi. So you can load this file using ClientDataset.LoadFromFile method in Delphi.
