When using a Fetch( ) function to retrieve the data from a url or other source, you can specify and filter results in your Interactions.
These functions can be naturally generated by the "Code Builder" in the Interactions Manager.
Basic Madl components used in the fetch of data for Interactions include: Before / After / Between.
$t->after( )
Fetches the source before $mystring into variable $t. Usually generated by the code builder when you have
select to filter the fetch results using the "To" field in the builder.
