Multiple nested filters can be used. In this case, the order of defining them is the order they will be executed at installation time.
Filters are embedded in the nested filters element like this:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<dynamicvariable ...>
... <!-- other nested arguments might go here -->
<filters>
<filter1 .../>
<filter2 .../>
... <!-- more filters might go here -->
</filters>
</dynamicvariable> |
