WebSource::Format - Format XML Nodes
A filter operator allows to select which input elements will be returned as output or not.
The default filter operator is a uniquness operator. It keeps track of items which it has had as input on only returns those which have never been seen yet.
It is declared as follows :
<ws:filter name="opname" forward-to="ops" />
The different current types of other operators are :
- tests : Filters elements based on a series of tests
- distance : Filters elements based on the number of times they or a parent object passed thru the filter
- script : Filters elements based on an external or inline script
- type : Filters elements based on their MIME type
For more details on each type of filter see the corresponding WebSource::Filter::<type> man page.
