Hi matrixebiz,

I'm not sure if I understand the question correctly, but it seems like you want to append a ID token key to the end of a url?

If the ID token key is of type string, then you can simply do stream.url = stream.url + ID Key like you stated.

If the ID token key is of type integer, then you can use the .toStr() function to convert the integer into a string like so:

stream.url = stream.url + ID_TOKEN_VARIABLE.toStr()

This is assuming that stream.url is the HLS stream url as a string and the ID_TOKEN_VARIABLE is an integer/float.
https://sdkdocs.roku.com/display/sdkdoc/ifIntOps

If not, the quickest way to go about checking how to append things would be to use the debugger as a REPL to figure out how things work:

You can create a breakpoint in your code by inserting a "stop" in the code where you want to break, telnet to the debugging port 8085/8089 on your Roku device and see what the types of the variable are by running "type(stream.url)" or type(VARIABLE) to check.

Hope that helps! Let me know if that was what you were asking or if you have any additional questions.

Ohhhh -- what is the _getXmlString method you used in the first post? How does it work and does it return a string or a xml element?

If I understand correctly, streamurl is in XML? In that case you might want to create a roXMLElement so that you can get the HLS stream as a string: https://sdkdocs.roku.com/display/sdkdoc/roXMLElement

So you create a roXMLElement (call it x, for simplicity) and use its parse() method on the XML EG you had: <streamUrl>http://stream/playlist.m3u8?id=</streamUrl> (call it "str")

I.e.

x =createObject("roXMLElement")
x.parse(str)

Then get the text:

somestring = x.getText()

Which will output the HLS Stream as a string (stored in variable somestring above)

Then, if Key is a string, append it by doing something like:

somestring = somestring + "1345n349jc380mcvw87wcd2" 

Not sure if that's the case, let me know if that works 😄

If you're having trouble understanding how to use roXMLElement, take a look at this example below:

  if str = invalid return
  xml = CreateObject("roXMLElement")
  ' Return invalid if string can't be parsed
  if not xml.Parse(str) return

  if xml <> invalid then
    xml = xml.getchildelements()
    responsearray = xml.getchildelements()
  end if

  result = []
  'responsearray - <channel>'
  for each xmlitem in responsearray
    ' <title>, <link>, <description>, <pubDate>, <image>, and lots of <item>'s
    if xmlitem.getname() = "item"
      ' All things related to one item (title, link, description, media:content, etc.)
      itemaa = xmlitem.getchildelements()
      if itemaa <> invalid
        item = {}
        ' Get all <item> attributes
        for each xmlitem in itemaa
          item[xmlitem.getname()] = xmlitem.gettext()
          if xmlitem.getname() = "media:content"
            item.stream = {url : xmlitem.url}
            item.url = xmlitem.getattributes().url
            item.streamformat = "mp4"

            mediacontent = xmlitem.getchildelements()
            for each mediacontentitem in mediacontent
              if mediacontentitem.getname() = "media:thumbnail"
                item.hdposterurl = mediacontentitem.getattributes().url
                item.hdbackgroundimageurl = mediacontentitem.getattributes().url
                item.uri = mediacontentitem.getattributes().url
              end if
            end for
          end if
        end for
        result.push(item)
      end if
    end if
  end for

Got it working. Thank you.
