I wouldn't even know how to begin a search for this issue, feedback from a Dune HD media player looks like this from a web browser,
param name="playback_speed" value="256"/>
param name="playback_duration" value="6836"/>
param name="playback_position" value="1886"/>
param name="playback_position_version" value="21"/>
param name="playback_repeat" value="0"/>
param name="playback_shuffle" value="0"/>
param name="playback_caption" value="Dark Phoenix (7 of 24)"/>

I am parsing out the data with
var duration = info.match("playback_duration\" value=\"(.*?)\"")[1];
var title = info.match("playback_caption\" value=\"(.*?)\"")[1];

each line works but I can only have one line in the script at a time. If I add both line to the script neither seems to work.

LRM - Edited to change the thread title to be more reflective of the ask.

Not sure if this will work but maybe between before each line that is doing a .match(...) , insert the following line.
info.lastIndex = 0;


You may have to convert your code to build Regular expressions and the do a myRegEx.match(info) to get this to work.

Can you please post an full example that will compile and run including the text that is in the variable named info? It's easy enough to do.

Sorry it took a while, hears the script I am running,
var url = CF.widget("DuneHD_URL","DuneHD_URL").label;
var CR = " HTTP/1.1\r\n\r\n";
function DuneHD_IP(command) {
var SEND = command.concat(CR);
var socket = new TCPSocket(false);
socket.onConnect = function()
{
socket.write(SEND)
};
socket.onData = function()
{
var info = socket.read();
info.lastIndex = 0;
var title = info.match("playback_caption\" value=\"(.*?)\\(")[1];
info.lastIndex = 0;
var duration = info.match("playback_duration\" value=\"(.*?)\"")[1];
GUI.widget("DuneHD_Title").label=title;
GUI.widget("DuneHD_Duration").label=duration;
socket.close();
};
socket.onIOError = function(e)
{
socket.close();
};
socket.connect(url,80);
};


the command being sent is,

when I display INFO in a panel and run the simulator, repeating query every 5 seconds, I noticed it switches between the above example to HTTP/1.0 200 OK

Is it being an XML file?

I got it working with adding

info = info.replace(/^<\?xml\s+version\s*=\s*(['"])[^\1]+\1[^?]*\?>/, "");

Great to hear!

I presume you got that RegEx from com.philips.Util.js or perhaps on the web somewhere?

Here's the original bug for XML processing about having to remove the XML preprocessor instruction via replace().

[Link: bugzilla.mozilla.org]

Now if you want to process that data without all the substrings and matches, try this one. Google for the single acronym "E4X"

ECMAscript for XML is available in the Javascript engine on the Pronto and will work after you remove that preprocessing instruction.

You can learn to use this "dead" extension to Javascript via Adobe Tutorials. My first version of a weather app many years ago processed XML data on the Pronto using the E4X extension.

[Link: help.adobe.com]

or from the specification

[Link: www-archive.mozilla.org]

Another tutorial as well.
[Link: w3schools.sinsixx.com]

Put this code into a button and run the simulator with ProntoScript Console.

It should give you some ideas as to how you could simplify your code drastically.

In this post, the line where 'text' is assigned, wraps. Make sure when you paste into button code that is all on 1 line.


System.setDebugMask(9);

var text = '<command_result><param name="protocol_version" value="4"/><param name="player_state" value="standby"/></command_result>';

var command_result = new XML(text);

var extractedParamsArray = [];
var extractedParams = {};
// For each loop to show each param by enumerating the XMLList.
for each (var param in command_result.param) {

//System.print(param.toSource());
// must use the . before @ as E4X needs to know to look inside param
// for attributes
var name = param.@name;
var value = param.@value;
//System.print(name + "=" + value);
extractedParamsArray.push({"name":name, "value":value});
extractedParams[name] = value;
}

System.print(extractedParamsArray.toSource());

System.print(extractedParams.toSource());


Here's the output I see locally:

protocol_version=4
player_state=standby
[{name:protocol_version, value:4}, {name:player_state, value:standby}]
({protocol_version:4, player_state:standby})

I got this to work but I don't see what your seeing, the player_State value does not change when playing vs not playing a movie, I only see,
[{name:protocol_version, value:4}, {name:player_state, value:standby}]
({protocol_version:4, player_state:standby})
I do not see,
protocol_version=4
player_state=standby

I also wonder for my DunePlayer the only values I get for Player_State, are
< param name="player_state" value="navigator"/>
< param name="player_state" value="file_playback"/>

My code is very glitchy, I think the issue may be that the return data bounce back and forth between the example listed above and " HTTP/1.0 200 OK", or at least that is what is being displayed when I display "info" in a panel on the remote. I repeat the code every 5 seconds. Not sure where the " HTTP/1.0 200 OK" is coming from, for I do not see it from a web browser.

What I don't understand is why I can only parse one at a time, once the data is loaded into 'info' shouldn't I be able to parse it out as much as I want too?


After doing a bit more digging, I am getting an error stating that
var title = info.match("playback_caption\" value=\"(.*?)\\(")[1];
has no properties..

The web browser communicates using the HTTP prototol and the 200 OK is the HTTP status for OK. Your web browser hides all of this and only gives you back whatever is in the Response Body.

In my example, 'text' variable contains ONLY the Response body (What you see as content in Chrome) I received when I connected to my Dune Player when the power was off.

For your example to work, you'd need to create an XML object out of all the data you received from ONLY the response body.

If this is over your head, please continue doing it the way you were but if you want to do it the best and most sane way, here's how. Replace your socket.onData function with the one below.


socket.onData = function()
{
var info = socket.read();
// Per WebMaster In a Nutshell from O'reilly books - Recommend this book for learning HTTP Protocol.
// Skip past the HTTP Response Status Line and any Response Headers.
var body = info.substring(info.indexOf("\r\n\r\n") + 4);
// Remove the XML Preprocessor instruction as you were doing before
body = body.replace(/^<\?xml\s+version\s*=\s*(['"])[^\1]+\1[^?]*\?>/, "");
var command_result = new XML(body);

// what we want to do here is to extract all params from XML response to an object as key-value pairs.
var extractedParams = {};
// For each loop to show each param by enumerating the XMLList.
for each (var param in command_result.param) {
// must use the . before @ as E4X needs to know to look inside param
// for attributes
var name = param.@name;
var value = param.@value;
extractedParams[name] = value;
}
// Now you have all the content in an XML object you can use as my example did.
// GUI.widget("PLAYER_STATE").label = extractedParams['player_state'];
GUI.widget("DuneHD_Title").label= '' + extractedParams['playback_caption'];
GUI.widget("DuneHD_Duration").label='' + extractedParams['playback_duration'];
socket.close();
};


Note that all this stuff will work if you don't have an titles that have UTF8 encoded characters. If you do, you may see errors on those titles.

For this reason, many of us use the Philips Http Library to do this processing as it handles the UTF8 decoding for us.

When you mention 'glitchy' code, please be aware that the Dune may send multiple blocks of data. You are not concatenating the strings received from the Dune but instead using what has just been sent.

var info = socket.read();

Your solution is not a robust solution in that if the Dune sends multiple blocks of data over the socket, your code will only process what was sent in that block.

That's why many of us use the Philips Http Library so that when the HTTP request has completed, we then read the data.

I have many examples of doing this locally in my setups. However, writing about how to do this here, requires lots of tutorials.

The Beta Dev guide included an appendix on using the Philips HTTP library. I cannot recall if they provided examples. Have you reviewed that before?

Thanks will start to try and rap my head around using the HTTP library's, I will stop what I have been doing and start over for it has not been working properly. LOL

Thnaks
Understand better now why it was not working, so at least I learned something.

Side question, does your Dune player sort movies properly? I have a large library and I have a handful of movies that are not listed in the proper alphabetical order. For an example the movie "The Mist" is the very first movie listed in my library. I have been in contact with support but not herd back yet. I have a DuneHD 4k solo, with the latest bata firmware that you can DL right from the unit installed

For this example, I get "undefined" displayed, if I'm lucking to get that, also not seeing any errors. Also your earlier example with the code to be placed in a button, I get "Empty String" where I should be seeing the returneddata.

M,

Please send me an email from an address that can receive a configuration file attachment and I will send you a working PEP2 one that you can play with. This configuration will install the HTTP library I use (both commented and non-commented - loads a little faster) versions.

I'm also including a printLine function that I used to ensure that we don't run into issues due to limitations in Pronto's System.print function.

The approach I used is 100% the best way to approach this problem. IMO, the Dune HTTP interface does not usually provide detail must users are looking for. As such, I don't use it at all.

I've tested this config with Blu Ray, DVD, .mkv, and Audio playlist playback. On my Dune, none of these show the parameter you cited above named 'playback_title'.

It is completely up to you to finish this off. But from the code I will give you, hopefully you can.

When you get the file, please make time to review all code in the DuneMonitor activity's script as well as the code in the DuneStatus page's script.

I conveniently used the pageInterval of 5 seconds on the DuneStatus page to get the refresh.
