Need help with XSL syntax

I am fairly new at XSL and XPath and this may be a noob type question but any help would be greatly appreciated. This is what I am trying to do:

I have XML that looks like this:
<?xml version="1.0" ?>
<RULES>
<EXECUTE_PROGRAM>
<PATHNAME>Program.exe</PATHNAME>
<COMMAND_LINE>/D=%MSG% /I=%INST% /S=Failed</COMMAND_LINE>
</EXECUTE_PROGRAM>
<EXECUTE_PROGRAM>
<PATHNAME>Program.exe</PATHNAME>
<COMMAND_LINE>/D:%MSG% /I:%INST% /S=Active</COMMAND_LINE>
</EXECUTE_PROGRAM>
<EXECUTE_PROGRAM>
<PATHNAME>Program.exe</PATHNAME>
<COMMAND_LINE>/D:%MSG% /I:%INST% /S=Active</COMMAND_LINE>
</EXECUTE_PROGRAM>
<EXECUTE_PROGRAM>
<PATHNAME>Program.exe</PATHNAME>
<COMMAND_LINE>Another valid command line</COMMAND_LINE>
</EXECUTE_PROGRAM>
<EXECUTE_PROGRAM>
<PATHNAME>Program.exe</PATHNAME>
<FLAGS>1001001</FLAGS>
</EXECUTE_PROGRAM>
</RULES>

I am trying to find all instances where the <COMMAND_LINE> node "contains" either '/S=Active' or '/S=Failed' or '/S=Success' when the <PATHNAME> is equal to 'Program.exe'. But here is the catch. I only want these nodes written when the '/S=Active' or '/S=Failed' or '/S=Success' shows up in the <COMMAND_LINE> more than 1 time. I also want to capture when it doesn't appear at all.

The transformed XML should look something like this:
<?xml version="1.0" ?>
<RULES>
<EXECUTE_PROGRAM>
<PATHNAME>Program.exe</PATHNAME>
<COMMAND_LINE>/D:%MSG% /I:%INST% /S=Active</COMMAND_LINE>
</EXECUTE_PROGRAM>
<EXECUTE_PROGRAM>
<SOME_NODE>/S=Success not found</SOME_NODE>
</EXECUTE_PROGRAM>
</RULES>

I have been banging my head against the wall with this one and any help would be greatly appreciated. TIA!

I thought I would post the XSL that I currently have as well:



This is the "Positive" of what I am looking for and brings back only those lines that meet that condition. I could put a "not" in front of it but then it would still bring back valid nodes even though they have the desired string and this isn't what I am looking for either. Any help would be greatly appreciated.
