here is a sample of xml for audio App

Archived

this may not be the best sample and sure it can be cleaned up a bit as well as for more error handling

here is what the xml should look like:

<songs>
    <song>
      <title>song title 1</title>
        <url>song url 1</url>
        <author>song author 1</title>
        <desc>description song 1</desc>
        <fmt>format of song (mp3)</fmt>
        <image>song image url 1</image>
    </song
    <song>
        <title>song title 2</title>
        <url>song url 2</url>
        <author>song author 2</title>
        <desc>description song 2</desc>
        <fmt>format of song (mp3)</fmt>
        <image>song image url 2</image>
    </song
</songs>

and this is what i used to populate the poster screen, again this is for the audio app and i used the mp3.brs

Function CreateSongList() as Object
    aa = CreateObject("roAssociativeArray")
    aa.posteritems = CreateObject("roArray", 10, true)
  
    m.UrlBase         = "http://XXXX.com/roku"
    m.UrlGetMp3Info  = m.UrlBase + "/xml/mp3Playlist.php"
    http = NewHttp(m.UrlGetMp3Info)
   
    rsp = http.Http.GetToString()
    xml = CreateObject("roXMLElement")
  
    if not xml.Parse(rsp) then
        print "Can't parse response"
        ShowConnectionFailed()
        return ""
    end if

    if xml.GetName() <> "songs"
        Dbg("Bad response: ",  xml.GetName())
        ShowConnectionFailed()
        return ""
    end if

    if islist(xml.GetBody()) = false then
        Dbg("No Song information available")
        ShowConnectionFailed()
        return ""
    end if

For Each song in xml.song
     'initialize variables with empty strings, just in case they're missing in the XML
    title = ""
    url = ""
    image = ""
    fmt = ""
    desc = ""
    author = ""

	title = song.title.GetText()
	url = song.url.GetText()
	author = song.author.GetText()
	image = song.image.GetText()
	fmt = song.fmt.GetText()
	desc = song.desc.GetText()

    song = CreateSong(title, desc, author, fmt, url, image)
    aa.posteritems.push(song)

Next
   
    return aa

End Function

Sub DoMp3(from as string)
    'Put up poster screen to pick a song to play
    SongList = CreateSongList()
    Pscreen = StartPosterScreen(SongList, from, "whatever you want here to display on screen")

    while true
        song = Pscreen.GetSelection(0)
        if song = -1 exit while
        Show_Audio_Screen(songlist.posteritems[song],"whatever you want here to display on screen")
    end while
End Sub

Hope that helps someone else, I got help from Endless and Jbrave on this thread

dynamite,
You don’t need the nested For…Next loop in that example. You only need that if you actually want to walk through the child elements. Since you’re grabbing them specifically via the song element (i.e., song.title.GetText()), you don’t need to wrap them in a loop. In fact, you’re actually calling those lines six times for each song right now, which is just additional overhead you don’t need.

Thanks I changed that !

Ok endless i have tried re using this example elsewhere and its not working, one thing is i am trying to use the xml that all the other feeds use in the video player example
the xml is like this

<feed>
	<item sdImg="http://xxxx.com/imagees/videos/1993.jpg" hdImg="http://xxxx.com/images/videos/1993.jpg">
		<title>Hernandez</title>
		<contentId>10001</contentId>
		<contentType>Fight</contentType>
		<contentQuality>SD</contentQuality>
		<media>
			<streamFormat>mp4</streamFormat>
			<streamQuality>SD</streamQuality>
			<streamBitrate>700</streamBitrate>
			<streamUrl>http://xxxx.com/roku/video/1993.mp4</streamUrl>
		</media>
		<synopsis>Leo Hernandez</synopsis>
		<genres>Clip</genres>
		<runtime>703</runtime>
	</item>	
	

	<item sdImg="http://xxxx.com/imagees/videos/1994.jpg" hdImg="http://xxxx.com/images/videos/1994.jpg">
		<title>Leo</title>
		<contentId>10002</contentId>
		<contentType>Fight</contentType>
		<contentQuality>SD</contentQuality>
		<media>
			<streamFormat>mp4</streamFormat>
			<streamQuality>SD</streamQuality>
			<streamBitrate>700</streamBitrate>
			<streamUrl>http://xxxx.com/roku/video/1994.mp4</streamUrl>
		</media>
		<synopsis>Leo</synopsis>
		<genres>Clip</genres>
		<runtime>703</runtime>
	</item>	

</feed>

here is what is what i have now and its not showing up anything

For Each item in xml.item
'initialize variables with empty strings, just in case they're missing in the XML
    title = ""
    url = ""
    image = ""
    fmt = ""
    desc = ""
    author = ""

    title = item.title.GetText()
    author = item.genres.GetText()
    image = item.image.GetText()
    desc =  item.description.GetText()

 song = CreateSong(title, desc, author, fmt, url, image)
 showList.Push(song)

but the reason i need to change this i do not want to have to go in and change all the xml i already have done for the video and do it differently for the audio
