Re^2: Trying to decode JSON streaming from a website

I added commas to the end of each line, and now JSON::SL is trying to decode at least now I'm getting a hash ref error...

JSON Stream parser test

Can't use string ("1402012831") as a HASH ref while "strict refs" in u
+se at client.pl line 38.

Should it not be using "sequenceNumber" as the reference and "1402012831" as the data? The line it fails on is print "$obj->{Value}{flowStartSeconds}: $obj->{Value}{senderCallsign}\n"; If I use Data::Dumper the first element looks like below, could it be I've got my JSON pointer wrong so it's not looking at the whole line?

$VAR1 = {
          'Value' => 1402024539,
          'Path' => '/sequenceNumber',
          'JSONPointer' => '/^'
        };

I'm not overly strong in OO Perl, I know I should how to use it more. Thanks

I don't know JSON::SL, but it seems that you have to configure it better to call your code at different times than it currently does. I don't know what kind of JSON path spec it implements, but have you tried just using `/` instead of `/^`? If you post a short, self-contained program that still reproduces the error, then we can give help more to the point than just guess about your data, your code and the behaviour of JSON::SL. See also SSCCE.	[reply] [d/l] [select]
