How can I monitor a folder for more than one file name pattern?

Question

What I would like is an example job that does the following:

1) File comes in, is fully downloaded and then kicks off a FolderWatcher Job

2) Based on the criteria the file name matches, it will kick off another task

3) Task 3: Job execution task

I have items 1 and 3, but need an example for item 2 (a task that has some logic to specify which task to call next). Ideally, it would be something akin to:

 ...
 if (FileName.FilterMatch1 = true)
 \{
            Call Task FilterMatch1Execute();
 \}
 elseif (FileName.FilterMatch2 = true)
 \{
            Call Task FilterMatch2Execute();
 \}
 else \{
            Call Task NoMatchExecute();
 \}
 ...

…or a switch case or what have you.

The following job-chain tests for more than one regexp, watching for different file-names:

 <?xml version="1.0" encoding="iso-8859-1"?>
 <job_chain  orders_recoverable="yes">
    <file_order_source  directory="\\asc-stg1p\hshare\ftptest\1420\Inbound\" regex="^08.*\.zip$|^13.*\.pgp$" next_state="NoNZ_checkSteadyState"/>
    <file_order_source  directory="\\asc-stg1p\hshare\ftptest\1420\Inbound\" regex="(^01.*|^02.*|^03.*|^04.*|^05.*|^06.*|^07.*|^09.*|^10.*|^11.*|^12.*|^14.*|^15.*|^16.*|^17.*|^18.*)\.pgp$" next_state="NZ_checkSteadyState"/>
 
    <job_chain_node  state="NoNZ_checkSteadyState" job="../checkSteadyState" next_state="NoNZ_setParams" error_state="!checkSteadyState" on_error="suspend"/>
    <job_chain_node  state="NoNZ_setParams" job="setParams-asc-stg1p-hshare-ftptest-1420-Inbound-NoNZ.pgp" next_state="step1" error_state="!NoNZ_setParams" on_error="suspend"/>
 
    <job_chain_node  state="NZ_checkSteadyState" job="../checkSteadyState" next_state="NZ_setParams" error_state="!checkSteadyState" on_error="suspend"/>
    <job_chain_node  state="NZ_setParams" job="setParams-asc-stg1p-hshare-ftptest-1420-Inbound-NZ.pgp" next_state="step1" error_state="!NZ_setParams" on_error="suspend"/>
 
    <job_chain_node  state="step1" job="../startJob" next_state="success" error_state="!step1" on_error="suspend"/>
 
    <job_chain_node.end  state="!checkSteadyState"/>
    <job_chain_node.end  state="!NoNZ_setParams"/>
    <job_chain_node.end  state="!NZ_setParams"/>
    <job_chain_node.end  state="!step1"/>
    <job_chain_node.end  state="success"/>
 </job_chain>

A job chain can have more than one file watcher (regexp). Every regexp can have a (different) next_state assigned. This is the state, where the job chain has to start processing. In this case, we have two different steps, one to check the steady state one to set the parameter for the "startJob".
