This view is displayed by default when entering Advanced rule mapping. A list of several predefined rule templates are displayed.

Each rule has a name and description to indicate its purpose. The default selection is Constant value.

The following rules are available.

Constant value

A Constant value is a rule where whatever is typed is used as the field value.

Find related node

The Find a related node rule is used when an XML file has multiple nodes for the same XML tag. You can use this rule to ensure that the correct value is returned.

Find related node (dv)

This rule is similar to the "Find a related node" rule. However, you can provide a default value that is used if no result is found.

Alternative node

The Alternative node rule is used when the same field value is found in multiple locations. For example, the same telephone number may be listed in multiple locations. You can choose which of these values is extracted.

Convert value

The Convert value rule is used when the value required by validation rules or back-end processing is different to the value found on a document. In this case, you can specify the value expected on a document and then provide alternative values.

Keep value

The Keep value rule enables you to specify an XML node that is likely to have multiple values. You can specify which of those values you want to keep.

Find related node 2

This rule is similar to the" Find related node" rule, except that you can supply two search values. If one is not found, it looks for the other.

Regardless of which rule is selected, you cannot edit the rule here. Instead, switch to Nodes view to make changes to the selected rule.
