Each mapping rule is an XML element within the mapping rule file. Each mapping rule element, except for one that specifies copying, has at least two sub-elements: <tag> and <value>. These two sub-elements determine whether the rule applies for any given element in an imported or exported XML file. If multiple rules in a file could apply to an element in an imported or exported file, only the first rule applies.

The following examples show the types of rules and how to apply them to a variety of attributes. To work with attributes that do not appear in the following examples, you need to understand XML and read the XML file that you are mapping.
