VOID expressions return no value but are used to
perform other work. The
VOID REMOVE_EXPORTED_PROP expression deletes the file
containing the value of an exported property and also the property value
itself, if desired.
Use
REMOVE_EXPORTED_PROP to remove a file created by the
VOID EXPORT_PROP or
VOID RETRIEVE_URL expressions. The following
expression nodes can modify
REMOVE_EXPORTED_PROP:
URL- Specifies the URL that files were written to. This value may be either an absolute path or a path relative to the location ofPipeline.epx.PREFIX- Specifies any prefix used in the file name to remove. This value often corresponds to the value ofPREFIXin theVOID EXPORT_PROPexpression.REMOVE_PROPS- Specifies whether to remove the property from the record after deleting the file where the property was stored.TRUEremoves the property from the record after removing the corresponding file.FALSEdoes not remove the property.
See the
EXPRESSION element for DTD and attribute information.
As the
COMMENT element indicates, this example removes the
temporary file created by
EXPORT_PROP.
