l Trim Option:Can either be "Trim"if you want to trim empty spaces before and after the
data selection or "NoTrim"if you want to retain the extra spaces.
Metadata selections
Metadata selections are used with any type of emulation, as long as a metadata file was
created by a previous task in the process.
Note
To get a sample of the metadata file, debug your process and step through it until the option View
Metadata gets enabled. This happens when metadata have been created by a task in the process.
Open the metadata viewer and save the metadata file to use it as a metadata sample file in the Data
Selector.
Syntax
GetMeta(Field Name [, Option Flags, Metadata Path])
Here is a breakdown of the syntax:
l GetMeta():Always surrounds metadata selections.
l Field/Attribute Name:specifies the name of the field (or attribute, if the GetAttribute
option flag is set) to retrieve (see "Metadata" on page35).
l Option Flag (optional):Sets the options for the selection (see table below).
l Metadata Path (optional):Defines the precise path where the Metadata Field is located.
Note
Metadata Index/Count values are zero-based: the first element in any collection
has an index of 0 and the last element's index corresponds to the collection's length
minus 1.
Option flags
The flag value to enter should be the sum of all desired flags. So, a value of 11, which is 8+2+1,
means that behavior 8, 2 and 1 are applied.
