Hello,

I am trying to figure out how to have two RSS's one for each row. Based on the code it looks like I need to have a second. "oneRow = GetApiArray()" but not sure how to call it "twoRow = GetApiArray()" Just not sure how to rename the "GetApiArray()" part of the code.

Thanks for the help,

Mike




Sub RunUserInterface()
screen = CreateObject("roSGScreen")
scene = screen.CreateScene("HomeScene")
port = CreateObject("roMessagePort")
screen.SetMessagePort(port)
screen.Show()

oneRow = GetApiArray()
list = [
{
TITLE : "Live Cameras"
ContentList : oneRow
}
{
TITLE : "Video Library"
ContentList : oneRow
}
]
scene.gridContent = ParseXMLContent(list)

while true
msg = wait(0, port)
print "------------------"
print "msg = "; msg
end while

if screen <> invalid then
screen.Close()
screen = invalid
end if
End Sub

To me it's not clear what you're asking. You have a function GetApiArray() and you want to create a parallel function, or you want to split your 'list' into multiple lists?

To different lists driven by a rss list. What do I need to change to support a each row driven by there own RSS file.

Sub RunUserInterface()
screen = CreateObject("roSGScreen")
scene = screen.CreateScene("HomeScene")
port = CreateObject("roMessagePort")
screen.SetMessagePort(port)
screen.Show()

oneRow = GetApiArray()
list = [
{
TITLE : "Live Cameras"
ContentList : oneRow
}
{
TITLE : "Video Library"
ContentList : oneRow
}
]
scene.gridContent = ParseXMLContent(list)

while true
msg = wait(0, port)
print "------------------"
print "msg = "; msg
end while

if screen <> invalid then
screen.Close()
screen = invalid
end if
End Sub


Function ParseXMLContent(list As Object)
RowItems = createObject("RoSGNode","ContentNode")

for each rowAA in list
'for index = 0 to 1
row = createObject("RoSGNode","ContentNode")
row.Title = rowAA.Title

for each itemAA in rowAA.ContentList
item = createObject("RoSGNode","ContentNode")
' We don't use item.setFields(itemAA) as doesn't cast streamFormat to proper value
for each key in itemAA
item[key] = itemAA[key]
end for
row.appendChild(item)
end for
RowItems.appendChild(row)
end for

return RowItems
End Function


Function GetApiArray()
url = CreateObject("roUrlTransfer")
url.SetUrl("http://www.railstream.net/*************/media.rss")
rsp = url.GetToString()

responseXML = ParseXML(rsp)
responseXML = responseXML.GetChildElements()
responseArray = responseXML.GetChildElements()

result = []

for each xmlItem in responseArray
if xmlItem.getName() = "item"
itemAA = xmlItem.GetChildElements()
if itemAA <> invalid
item = {}
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
end if
end for
end if
end for
result.push(item)
end if
end if
end for

return result
End Function


Function ParseXML(str As String) As dynamic
if str = invalid return invalid
xml=CreateObject("roXMLElement")
if not xml.Parse(str) return invalid
return xml
End Function

Sorry I don't have the answer to your question but I strongly suggest you use the "Code" tag (at the top of the comment box) to make the code in your comments more readable.
