Re: accessing data from json array of json arrays

My initial thougt was that i can do the data filtering directly in the json 
array and ommit the intermediate legacy array. my existing promise splits 
the  output of the lslpp command into an array. as this command is somewhat 
cpu intensive i contemplated with the inventory file solution. so i learned 
data filtering is not possible in an json array.
bundle agent get_lpp_info(fileset) 
{ 
vars: 
"lslpp_info" string => execresult ("/usr/bin/lslpp -O u -cl $(fileset) | 
/usr/bin/grep -v '^#'", "useshell"),
comment => "get info from lslpp fileset"; 
"info_array" slist => splitstring("$(lslpp_info)", ":", 8), 
comment => "get each field from lslpp output"; 
"lpp_version" string => nth("info_array", 2); 
"lpp_status" string => nth("info_array", 4); 
"lpp_long_desc" string => nth("info_array", 6); 

reports: 

"Time: $(sys.date) - Bundle: $(this.bundle) - Message: [$(lslpp_info)] 
reported by lslpp." 
comment => "do not remove this report .. won't call lslpp otherwise .."; 
"$(lslpp_info)" bundle_return_value_index => "0", 
comment => "give output back as index[0] (makes grepping for 'not 
installed' possible";
"$(lpp_version)" bundle_return_value_index => "1"; 
"$(lpp_status)" bundle_return_value_index => "2"; 
"$(lpp_long_desc)" bundle_return_value_index => "3"; 
}

in the end, i need the version number to upgrade aix filesets if downlevel. 
until now, i did this by exuting plain old system commands, but i thought 
it would be cool to use the already existing inventory file. anyway…your 
example helped a lot…. as always ;-) thank you for that 

Cool, what specifically was enlightening in the example I posted?
