selectall

You can use a selection to collect records (with getselections) for some common goal, like storing them in a saved search (aka pointer file).
All records found by the most recent search will be selected, not just the retrieved records. So if a search finds 315 records, while only the first 10 are actually retrieved, then still all 315 records will be added to the selection.
A selection can only be made if in the current session a search yielded a result set, and you want to select one or more records in that result set. The selection remains intact during the current session and applies only to this session (so you won't be able to observe a WebAPI record selection in your Collections application). In the return XML, selected records have the attribute selected="True" present in the <record> node, for example: <record priref="2" selected="True">. By default, retrieved records are not selected.

Syntax

command=selectall

• output (String) [optional] output format to be returned. Values for output can be either json or xml (xml is the default, so you don't need to specify that explicitly). However, the output format produced by jQuery applications is always JSON, so you don't need to specify the output type there either.

• callback (String) [optional] returns JSON output wrapped in brackets with your callback function name, for AJAX requests: <callback function name>( <JSON output> ); You don't need to specify output=json, because the output format is JSON by default.
