VOID expressions return no value but are used to perform other work. The VOID IMPORT_PROP expression imports a property value from a specified file.

Typically, files containing property values were created using the complementary expression VOID EXPORT_PROP. Another typical use of IMPORT_PROP is to read a document body created by VOID RETRIEVE_URL. (This is useful for HTML pre-processing with a spider.)

The property to import can be specified in either one of the following ways:

The following expression nodes modify IMPORT_PROP. Several of these nodes are the same as those used to identify the property during export in EXPORT_PROP.
