Adding dynamic data to object properties

You can apply variable data on the following object properties by setting a modification on the property:

•	Barcode properties and barcode data

•	Chart properties and chart data

•

URIs

•	Story selection for external content substitutions

•	Page selection for Fragments

•	Object size and positions in x- and y-directions

•	Page properties

•	Shape properties

•	Character properties for substitutions

If a property has a modification specified for it, there is an orange box around the property value and the value is displayed in italic.

The modification is defined by an XPath expression shown at the bottom of the Properties panel. For information on XPath, see Specifying output format.

Note:

The XPath expression must always evaluate to no value or exactly one value. An exception is thrown if:

–	Two or more values are returned.

–	The value has a bad format, e.g. a string when a numeric value is expected.

No modification is made on the property if:

–	No value is returned.

–	An empty string is returned from an XPath expression that evaluates font or color changes.

When setting a modification on any of the following enumeration properties, the evaluated values must be numeric: Visibility, Size mode, Positioning, Alignment, Vertical height, and Scale mode. For numbers corresponding to the property values, see the StGetProperty() script function in the Scripting Reference. When setting a modification on a property that is measured in units, the evaluated value is always in points. A point is 1/72 of an inch. To convert inches or millimeters to points, you can use the in2pt() and mm2pt() script functions.
